Intraventricular haemorrhage and hydrocephalus caused by intraventricular parasitic granuloma suggesting cerebral sparganosis.
A 67-year-old female farmer presented with acute loss of consciousness. Computed tomograms showed a calcified mass in the cavum septi pellucidi with intraventricular haemorrhage and obstructive hydrocephalus. The patient became fully conscious after urgent external ventriculostomy and subsequently underwent craniotomy for the excision of the mass. Pathological examination of the mass demonstrated a granuloma surrounding a degenerating larva compatible with Spirometra mansonoides whose mimicking an intraventricular tumour has not been reported before.
