Abstract
Background: Vascular malformations can present with hydrocephalus following external compression of ventricular outlet. This can be managed by a CSF diversion. Case presentation: We report a case of hydrocephalus secondary to a congenital venous anomaly treated successfully with cerebrospinal fluid diversion. Here we present a case to literature of a 57 years old male patient who had presented with hydrocephalus secondary to aqueductal obstruction by developmental venous anomaly. Patient underwent right ventriculoperitoneal shunt placement and post operative Computed Tomography showed reduction in size of bilateral lateral ventricles and third ventricle. Conclusion: Although developmental venous anomaly as a cause for hydrocephalus have been reported, we present one more case of hydrocephalus secondary to a congenital venous anomaly who was treated successfully with cerebrospinal fluid diversion.
Background
Aqueduct of Sylvius, a channel connecting third and fourth ventricle situated in the dorsal midbrain, surrounded by periaqueductal gray matter is the narrowest part of CSF pathway and the commonest site of CSF flow obstruction [1]. Commonest etiology for aqueduct cerebrospinal fluid flow obstruction include congenital stenosis and gliosis secondary to inflammatory conditions, tumors [2]. While vascular malformations form an infrequent cause of aqueductal obstruction, developmental venous anomalies are extremely rare with only about 10 cases reported so far [3]. Here we report a case of developmental venous anomaly in a 57 years old male causing obstruction of aqueduct of sylvius thereby causing hyrodephalus.
