Fowler syndrome and fetal MRI findings: a genetic disorder mimicking hydranencephaly/hydrocephalus.

Pediatr Radiol 2018 07 14;48(7):1032-1034. Epub 2018 Mar 14.

University of Cincinnati College of Medicine, Cincinnati, OH, USA.

Fetal ventriculomegaly is a common referral for prenatal MRI, with possible etiologies being hydrocephalus and hydranencephaly. The underlying cause of hydranencephaly is unknown, but many have suggested that the characteristic supratentorial injury is related to idiopathic bilateral occlusions of the internal carotid arteries from an acquired or destructive event. Fowler syndrome is a rare genetic disorder that causes fetal akinesia and a proliferative vasculopathy that can result in an apparent hydranencephaly-hydrocephaly complex. Read More

The appearance of untreated severe hydrocephalus with long-term survival is infrequent; here we report a case with these characteristics, mild neurological alterations and kidney and skeletal anomalies. A female patient showed severe hydrocephalus (initially mistaken with hydranencephaly) at 4 years old and left kidney ectopia (initially mistaken with renal agenesis); however, she was derived to the neurology service until she was 12 years old, when she began to present migraine and seizures. At 13 years old the patient was diagnosed with arrested hydrocephalus secondary to aqueduct stenosis, and the seizures worsen thereafter from atonic seizures to complex partial seizures (at 14 years old), presenting generalized seizures at 15 years old.
