This patient presented with fever followed by severe headache and persistent vomiting. Blood reports were suggestive of thrombocytopenia and slightly low hemoglobin levels. CSF culture report was negative for any organisms, with normal CSF sugar and CSF protein levels. CT brain was suggestive of hydrocephalus. It was followed by a contrast-enhanced MRI scan of the brain. MRI features were as described above, causing raised intracranial pressure. The patient underwent a posterior fossa craniotomy for removal of mass lesion in toto, with reservoir insertion. Histopathology confirmed the diagnosis of cysticercosis. Post-surgery, the patient recovered.

On questioning, the patient had a history of ingestion of pork few times. The hyperintense focus seen on FLAIR images within the 4th ventricular lesion, most likely represents scolex.
