Combined Intracerebral and Cranial epidural Hydatid Cysts: Case Report

Abstract

Background: Hydatid cyst (HC) is a parasitic disease caused by Echinococcus granulosus. Involvement of the central nervous system (CNS) is very rare in this parasitic infection and the association of intracerebral and epidural HC is exceptional. Patient and method:A 06-year-old female who was operated three years ago for a left frontal intracerebral hydatid cyst in Toto without rupture and without medical treatment following the surgery, and who came with the history of headache and vomiting for 4 months is reported. Computed tomography of the brain showed a large 5x6x5cm, cystic lesion with a density similar to the cerebrospinal fluid in the left frontal region with another adjacent small cyst in epidural space. The patient underwent left frontal craniotomy. The patient was treated by Dowling technique for intracerebral cyst and by cyst aspiration after rupture. Conclusion:Hydatid cysts in epidural location are very rare and can be primary or after recurrence. The mainstay of treatment is surgical removal of the cyst. Medical therapy is also important to prevent recurrences during the postoperative period.
