IVth ventricular neurocysticercal cyst: A rare cause of acute hydrocephalus

An 11-year-old boy presented with acute-onset projectile vomiting, bifrontal headache, and altered sensorium. Contrast-enhanced MRI brain was suggestive of intraparenchymal and intraventricular neurocysticercosis, with an intraparenchymal ring-enhancing lesion with central scolex in the left cingulate gyrus and a large cyst enlarging the IVth ventricle, with obstructive hydrocephalus (figure).1 Intraventricular cysticerci with acute hydrocephalus are rare.1 In contrast to intraparenchymal cysts, intraventricular cysts are large and typically lack an identifiable scolex.2 Confirmation of cysticerci is based upon identification of scolex in the intraparenchymal lesion or use of high-resolution T2 MRI sequences, which are superior in identifying scolex in intraventricular cysts.3
