Unilateral hydrocephalus fetal

The vast majority of congenital hydrocephalus patients develop it as of a bilateral symmetrical process, while in the less common type of obstructive hydrocephalus, as in this case, only one-sided lateral ventricular dilatation is seen Unilateral Hydrocephalus: Prenatal Sonographic Diagnosis Randall M. 2 Westudied sixcases ofunilateral hydrocephalus detected prenatally toanalyze the Laurence A.Mack1 sonographic features oftheabnormality andtodetermine thecauseandclinical Harris J.Finberg3 outcome. Inallcases,third-trimester sonograms showed marked unilateral latera Unilateral hydrocephalus is usually acquired later in life as a result of obstruction of the foramen of Monro from non-specific inflammatory reactions, tuberculosis, bacterial meningitis, thalamic or pedunculated intraventricular tumors and vascular malformations. Congenital unilateral hydroencephalus is a rare condition ✓ Unilateral hydrocephalus is an uncommon entity which results from obstruction at the level of the foramen of Monro. It is usually brought about by tumors or inflammatory conditions. Congenital maldevelopment of the foramen of Monro is an often postulated, yet never proven, cause of unilateral ventricular enlargement

Congenital unilateral hydrocephalus Radiology Case

  1. Hydrocephalus is a brain development disorder related to an excessive accumulation of cerebrospinal fluid (CSF) in the ventricular system. The functional relevance of cortical structural changes described in this disease is largely unexplored in human
  2. Unilateral hydrocephalus (UH) is an uncommon type of hydrocephalus, often congenital. In congenital hydrocephalus, vast majority of cases are bilateral, symmetric hydrocephalus with high rate of association with CNS and extra-CNS anomalies and a mortality rate up to 85%
  3. Mild non-progressive unilateral ventriculomegaly of 11-13 mm was regarded by Senat et al28 as a variation of normal fetal anatomy with a favourable neurological outcome. They reported 14 cases and reviewed another 38: overall 42 (88%) of the 48 survivors were thought to have normal cognitive development
  4. a and usually cause bilateral obstruction
  5. The child was diagnosed as having unilateral hydrocephalus due to congenital obstruction of the foramen and underwent a ventriculoperitoneal shunt operation on day 49 (37 weeks and 5 days of amended gestation age; 1,420 g body weight). The postoperative course was uneventful and the patient was discharged on day 126 with no marked developmental.
  6. Unilateral hydrocephalus is asymmetrical dilation of one lateral ventricle caused by obstruction of foramen of monro, and is distinct from unilateral ventricular enlargement caused by asymmetrical cerebral hypoplasia or atrophy
  7. Unilateral hydrocephalus is rare, and is usually associated with a neoplasm or inflammatory response at the foramen of Monro. It is even more uncommon with congenital atresia of one foramen of Monro. We report the fifth such case documented in the perinatal period, and the second case of unilateral hydrocephalus diagnosed by prenatal ultrasound

Unilateral hydrocephalus: prenatal sonographic diagnosis

Fetal cerebral ventriculomegaly is defined as an atrial diameter of ≥10 mm on prenatal ultrasound.3, 4, 5 The atrium of the lateral ventricle is the part at which the body, posterior horn, and temporal horn converge (); the atrial diameter remains stable between 15-40 weeks of gestation.The mean diameter of the lateral ventricle has been reported to range from 5.4-7.6 mm, and a. Congenital hydrocephalus and ventriculomegaly can be diagnosed reliably with prenatal ultrasound and Magnetic Resonance Imaging (MRI). Unilateral hydrocephalus is uncommon, and the prognosis depends on etiology and postnatal management. Here, we present a case of a 32-years-old woman with prenatal. In fetuses with apparently isolated unilateral ventriculomegaly, no chromosomal abnormalities were identified and the pooled prevalence of congenital infection was 8.2% (95% CI, 3.6-14.5%). The pooled prevalence of additional brain abnormalities detected prenatally and postnatally by magnetic resonance imaging was 5.1% (95% CI, 0.2-16.1%) and 6.

Congenital lateral ventriculomegaly

Fetal ventriculomegaly can be symmetrical, affecting both lateral ventricles (bilateral), or unilateral; however the majority of studies reporting the perinatal and long-term outcomes in fetuses with an antenatal diagnosis of fetal ventriculomegaly have assessed the bilateral condition 6. The aim of this study was to undertake a systematic. A 4-month-old afebrile baby boy was brought in with a history of 2 absence seizure-like episodes since birth. MRI brain revealed unilateral hydrocephalus involving left lateral ventricle (figure 1). Thin coronal and sagittal T1-weighted images showed membrane obstructing left foramen of Monro (figure 2) Unilateral ventricle dilation, unrelated to ex-vacuum hemisphere atrophy,[] is caused by unilateral foramen of Monro (FM) obstruction.[22 80] It may be just an obstructed compartment within a more complex hydrocephalus or a unique compartment with hydrocephalus.Hydrocephalus caused by unilateral FM obstruction has been referred to in literature by many different terms

Borderline lateral cerebral ventriculomegaly, isolated Gianluigi Pilu, MD . Bologna, Italy pilu@mbox.queen.it. Synonyms: Mild hydrocephalus, mild ventriculomegaly. Definition: mild enlargement of the lateral ventricles (atrial width 10-15 mm) in the absence of other sonographically demonstrable CNS anomalies. Prevalence: uncertain. An atrial width of 10 mm is about 3 standard deviations above. Prenatally, a common convention is to use the term ventriculomegaly when the fetal ventricles are mildly enlarged and hydrocephalus when they measure >15 mm or an obstructive etiology associated with increased CSF pressure is evident. Fetal cerebral ventriculomegaly is a relatively common finding on second trimester obstetric ultrasound.

Unilateral fetal hydrocephalus is a rare pathology, there are only few series of cases reported. The main cause of this abnormalitie is a obstrucrion of the foramen of Monro. The lateral brain ventricles are communicated through the foramen of Monro brain to the third ventricle. This communication can be obstructed by multiple causes such a The causes of unilateral hydrocephalus were agenesis or stenosis of the foramen of Monro in three cases, transient obstruction of the foramen in one fetus with an intraventricular hematoma, underlying brain dysplasia in one fetus with a variant of holoprosencephaly, and undetermined in one case Hydrocephalus is a relatively common developmental abnormality, but its underlying mechanisms are not well understood. NINDS supports a wide range of studies that explore the complex mechanisms of normal and abnormal brain development. For example, NINDS-funded researchers are trying to find gene mutations associated with congenital hydrocephalus

6. Unilateral / Asymmetrical Hydrocephalus. Detection or unilateral or asymmetrical hydrocephalus is difficult to diagnose unless the fetus is scanned through the sutures or fontanelles so that the near field ventricle is not obscured by reverberation artifact. · Ventricular atrium > 10 mm. · > 2 mm discrepancy between the two sides Prenatal diagnosis of unilateral hydrocephalus Prenatal diagnosis of unilateral hydrocephalus Anderson, N.; Malpas, T.; Davison, M. 1993-03-01 00:00:00 247 23 23 1 1 N.

It can occur in patients with hydrocephalus and different size ventricles caused by congenital or acquired unilateral brain atrophy. Durfee et al., reserve the term AH for cases where asymmetrical dilation of the lateral ventricles has more than 2 mm, thus including patients sustaining bilateral and unilateral ventricular ectasia.

Fetal hydronephrosis is the swelling of the kidney when too much urine collects in the pelvis (or basin) of the kidney. This occurs because there is a blockage of the normally free flow of urine, most commonly in the ureter (the tube that connects the kidney to the bladder), and the urine is not allowed to drain into the bladder We investigated cortical excitability using multimodal transcranial magnetic stimulation (TMS) in a case of congenital hydrocephalus with almost no neurological signs. Methods: A caucasian 40 years old, ambidextrous and multilingual woman affected by occult spina bifida and congenital symmetrical hydrocephalous underwent a TMS study Astrocytomas. Astrocytomas are the second most common congenital CNS tumor and represent a wide range of pathologies from subependymal giant cell astrocytomas to glioblastoma multiforme[].The appearances on ultrasound are of a unilateral echogenic mass within the cerebral hemisphere, which may have internal hemorrhage and often causes midline shift

Porencephaly (Gr.Poros a passage, ford, pore) was originally defined as a defect that creates a communication between the cerebral ventricles and the subarachnoid space but now, it it used to describe any fluid-filled cavity in the fetal or neonatal brain. A thin membrane may separate the cavity from the lateral ventricle or the subarachnoid space. Such membranes rupture in life or during the aut Advances in fetal diagnostic techniques have opened many areas to prenatal anatomical scrutiny. Intrauterine hydrocephalus and ventriculomegaly are conditions which are readily diagnosed. Fetal intervention has been undertaken in humans in order to minimize the craniofacial disfigurement and to maximize the growth potential of the brain Recommendations for patients with fetal ventriculomegaly include continued prenatal monitoring of head circumference and body size. In patients with hydrocephalus or a dysplastic brainstem, there can be increased risk of polyhydramnios if the fetus stops effectively swallowing amniotic fluid. 3 Therefore amniotic fluid status should also be monitored Unilateral mass effect from pathology in the frontal, parietal or temporal region, such as haemorrhage or tumour, causes displacement of the brain away from the mass. Complications are contralateral hydrocephalus (due to obstruction of the foramen of Monro) and anterior cerebral artery territory infarct (due to compression of ACA branches)

Introduction. Ventriculomegaly is the most common abnormal finding that leads to a diagnosis of fetal central nervous system (CNS) pathology and is the most common indication for second-level neurosonography and fetal magnetic resonance imaging (MRI) 1-4.Determination of its severity is based on strict criteria derived from the width of the atrium of the lateral ventricle 5: ventriculomegaly. Congenital Hydrocephalus. Hydrocephalus is a common CNS abnormality with frequent onset prenatally or in infancy. Expansion of the ventricles due to increased CSF production or diminished outflow is associated with progressive expansion of the ventricles and compression of the cortical and brainstem parenchyma. The hallmark of a unilateral. If unilateral - benign.• Consider - Fetal MRI - Fetal ECG . - Fetal corpus callosum assessment - Fetal karyotyping. - First trimester screening.• To note : - X linked variety of hydrocephalus develops in lateral gestation.• Caesarean section may have to be opted due to associated macrocrania. Meticulous serial ultrasound during gestation detected congenital unilateral left hydrocephalus by the 8th month. At birth the head circumference was 36.8 cm (+1.7 SD). Neurosurgery consultants opted to avoid surgical intervention. No signs or symptoms of increased intracranial tension were present and patient had no history of seizures Literature review shows that it is a very uncommon entity. Lateral ventricle CCs as a cause for unilateral hydrocephalus is a very rare entity. Neuroendoscopic approach is a first-line treatment option for this condition. Introduction. Colloid cysts (CCs) are rare congenital lesions, representing only 0.5%-1.0% of primary brain tumors,.

Congenital unilateral ventriculomegaly is a rare condition, usually caused by obstruction of the foramen of Monro. In the past, this condition required surgical intervention. We present a female newborn with non-progressive unilateral ventriculomegaly which was initially detected by prenatal sonography. No surgical intervention was performed, and during the 9 months of follow-up, she had. Congenital hydrocephalus is present in the infant prior to birth, meaning the fetus developed hydrocephalus in utero during fetal development.The most common cause of congenital hydrocephalus is aqueductal stenosis, which occurs when the narrow passage between the third and fourth ventricles in the brain is blocked or too narrow to allow sufficient cerebral spinal fluid to drain Ventriculomegaly is often considered the tip of the iceberg, because it is a finding frequently associated with numerous cerebral anomalies. The causes of ventriculomegaly are multifold, but they may be divided into three main categories: obstructive, dysgenesis, or destructive causes (Table 7.1 ). Table 7.1 Congenital posterior fossa abnormalities represent a wide variety of disorders that include both malformations and disruptions. These disorders may involve a single structure within the posterior fossa (eg, the cerebellum alone) or a combination of structures (eg, the pons and cerebellum) This condition occurs in approximately one in 1,000 infants. Typically, ventriculomegaly only requires treatment if it causes hydrocephalus. Since the excessive pressure caused by the buildup of cerebrospinal fluid in hydrocephalus can lead to serious, long-term neurological damage, prompt treatment is a must

Head echogram of a fetus with hydrocephalus and dilation of the lateral ventricle. The ratio between the distance from the midline to (1) ventricular wall (+), and (2) inner aspect of the parietal bone (x) is used to assess severity of the condition. In this fetus, the ratio is 67% (normal is approximately 35%) Persistent fetal vasculature, previously known as persistent hyperplastic primary vitreous, is a spectrum of disease and can present with no clinical effects or with severe morbidity.This condition arises from failure of the hyaloid vasculature to undergo normal programmed involution. During development, this fetal vasculature nourishes the developing lens and vitreous. 1 Any abnormalities. • Congenital hydrocephalus - a buildup of cerebrospinal fluid (CSF) in the brain that is present at birth. It can lead to permanent brain damage as well as strabismus and high refractive errors. In order to identify the underlying cause for the unilateral high myopia, it may be necessary to perform ancillary testing Choanal atresia seen during exam Choanal atresia is a congenital narrowing of the back of the nasal cavity that causes difficulty breathing. It is rare, occurring in approximately 1 in 7,000 live births, and is seen more often in females than in males. Choanal atresia is often associated with other developmental anomalies such as CHARGE.

Schizencephaly is a rare congenital (present from birth) brain malformation in which abnormal slits or clefts form in the cerebral hemispheres of the brain. The signs and symptoms of this condition may include developmental delay, seizures, and problems with brain-spinal cord communication.People with schizencephaly may also have an abnormally small head (microcephaly); hydrocephalus. Uniloculated hydrocephalus is dilatation of one segment of the ventricular system due to obstruction at the foramen of Monroe causing unilateral ventricular dilatation. Alternatively, obstruction at the cerebral aqueduct and fourth ventricular outlet may cause dilatation of the fourth ventricle [ 31 ]

Hemiplegia in infants and children is a type of Cerebral Palsy that results from damage to the part (hemisphere) of the brain that controls muscle movements. This damage may occur before, during or shortly after birth. The term hemiplegia means that the paralysis is on one vertical half of the body Coronal craniosynostosis is the second most frequent type of craniosynostosis (accounting for 20-30 percent of cases). Unilateral coronal craniosynostosis can be either genetic or due to fetal head constraint from an aberrant fetal lie, multiple gestation, or small uterine cavity [Graham et al., 1980; Higginbottom et al., 1980]
