Subdural hydatid cyst presenting as recurrent subdural hygroma

Abstract

Intracranial hydatid disease is an uncommon entity that usually is parenchymal in location. Presence of hydatid cyst in subdural location is being reported for the first time in the literature. A 13-year-old female child with the diagnosis of hydatid disease of brain was operated. She was advised to take albendazole which she did not take. In postoperative period she developed recurrent subdural hygroma for which multiple surgical interventions were done and finally cause of recurrent subdural hygroma was found to be hydatid cyst in the subdural space. The patient had initially undergone craniotomy for the excision of hydatid cyst. Later on she developed subdural hygroma for which the burr hole drainage was done twice. At time of third recurrence subduro-peritoneal (SDP) shunt was done. When she had recurrence again along with hydrocephalus, than VP shunt and revision of the SDP shunt was planned. While doing revision of SDP shunt, hydatid cyst was seen emerging from the burr hole site. A craniotomy was done to remove the hydatid cyst from the subdural space. Since then there has been no recurrent collection. Complete surgical excision is the best treatment modality to treat hydatid cyst of brain. Accidental spillage of the contents can have lead to recurrence, so every effort must be taken to prevent spillage of contents. Postoperatively all the patients must be put on antihelminthics.
