Abstract

Aim To describe the epidemiological and clinical criteria of those patients with rare intracranial cysts. Background Central nervous system (CNS) hydatid cysts are a rare presentation of hydatid cyst, although may be the cause of intracranial space-occupying lesions in 4% in endemic countries. It affects mostly children. The diagnosis of CNS hydatid is still problematic despite the advancements in imaging techniques (computed tomography or MRI). Extirpation of the intact cyst is the treatment of choice, resulting in most cases to a complete recovery. Patients and methods A retrospective descriptive study was conducted on the CNS hydatid cases operated in our departments between 2011 and 2016. A total of 16 cases were included. For each case, we reviewed the presenting clinical manifestations and the imaging findings. The Glasgow Outcome Scale was followed for all cases throughout the follow-up period. Results Of 16 cases, 12 were children (<12 years). The most presenting findings were increased intracranial pressure. A single cyst was detected for 14 cases, whereas multiple cysts were identified in two cases. Extirpation of the cyst without rupture was achieved in 12 patients. Only two cases developed recurrent hydatid after 3 years. No intraoperative mortality was detected, whereas postoperative mortality occurred in one case owing to anaphylaxis following intraoperative rupture of the cyst. Conclusion Surgical excision of the whole hydatid cyst without rupture is the treatment of choice to avoid the life-threatening complications of CNS hydatid rupture.
