Geometric Variability in Radiological Appearance of Third Ventricle in Congenital Hydrocephalus-Is it Really so Pliable? Or Do we Need to Visualize it Differently? A Two-Case Study and Literature Review

Enlargement of third ventricle is seen due to multiple causes, usually associated with hydrocephalus. Raised Intracranial Pressure (ICP) is the most common indication for a cerebrospinal fluid diversion procedure. However, congenital anomalies like Dandy Walker Malformation (DWM) may not always manifest with raised ICP. Identifying neurological delay and neurocognitive parameters and correlating this with existing anatomical features is extremely important. We discuss this report of two cases of patients with DWM where abnormal morphology of the third ventricle was analysed and used to interpret clinical neurological delay.
