Abstract:

Obstructive hydrocephalus is a condition marked by the accumulation of Cerebrospinal Fluid (CSF) in the brains ventricular system, which leads to increased intracranial pressure. Aqueductal stenosis, a rare cause of obstructive hydrocephalus, involves the narrowing of the aqueduct of Sylvius and may result from congenital malformations, tumors, or inflammatory processes. This condition can present with various symptoms, such as headache, nausea, vomiting, and cognitive impairment. However, presentations can sometimes be subtle, as with cerebellar ataxia. In this case report, we discuss a patient with obstructive hydrocephalus due to aqueductal stenosis who exhibited cerebellar ataxia, a neurological disorder characterized by coordination and balance difficulties. The patient’s presentation included abnormal body movements affecting the right side of her upper and lower extremities. MRI findings disclosed a linear band of tissue (web) at the aqueduct of Sylvius’s inferior part, with funneling at the superior part leading to severe ventricular dilation and an associated transependymal leak. This case underscores the necessity of considering obstructive hydrocephalus in the differential diagnosis of cerebellar ataxia and the critical nature of early intervention and meticulous monitoring. Furthermore, it highlights the need for a multidisciplinary approach to management.
