Background:

The current study aimed to assess the role of microsurgical treatment of patients with supratentorial cavernoma with epilepsy based on analysis of our patients.

Methods:

This retrospective study included 23 patients with supratentorial cavernoma on computed tomography (CT) scan and magnetic resonance imaging (MRI) of the brain admitted to the Department of Neurosurgery, Assiut University Hospitals (single tertiary hospital) between January 2014 and January 2018 (minimum 12-month follow-up). Deep-seated hemispheric and multiple cavernomas were excluded. Radiographs and hospital data of the patients were gathered and analyzed. All patients underwent the surgical procedure by one experienced neurosurgeon and the diagnosis was confirmed by pathologic evaluation.

Results:

A total of 23 patients underwent surgical intervention consist of 15 (65%) men and 8 (35%) women. Their age varies from 11 to 59 year with an average of 36.6 years. All patients presented with seizure. The supratentorial cavernomas were located commonly in temporal lobes; 9 patients (39.1%). 19 (83%) of cavernoma located in the left side. 18 (78%) of cavernoma had a size <2 cavernoma. Complete excision was confirmed in postoperative investigations (CT and MRI brain images). All 10 patients with only one seizure preoperatively were seizure free at follow-up. Of nine patients who had experienced between two and five seizures preoperatively, 7 (78%) were seizure free, and of four patients with numerous seizures preoperatively, 3 (75%) were seizure free.

Conclusion:

Our retrospective population study demonstrates an insight into the supratentorial cavernoma and suggests that microsurgical removal of the symptomatic cavernoma is generally accepted as the most effective and safe method.
