Obstructive hydrocephalus of uncommon etiology: case report and neurosurgical management of aqueductal web presenting in adolescence.

Abstract

Introduction: Aqueductal webs are a rare cause of obstructive hydrocephalus. Accurate diagnosis and intervention can prevent neurological complications.

Case presentation: Herein, we describe a case of a child presenting with headaches and vomiting. Magnetic resonance imaging (MRI) revealed obstructive tri-ventricular hydrocephalus caused by an aqueductal web. Endoscopic third ventriculostomy (ETV) was successfully performed to restore cerebrospinal fluid (CSF) flow.

Conclusion: This case underscores the importance of phase-contrast and T2-weighted cinematic magnetic resonance imaging of cerebrospinal fluid flow for diagnosis of aqueductal webs. These modalities provide valuable insights into CSF dynamics and guidance of appropriate neurosurgical intervention.
