Clinical case of an atypical variant of Labbe's vein structure in a patient with pharmacoresistant temporal epilepsy

Abstract

Among the commonly recognised structural lesions that cause drug-resistant temporal lobe epilepsy, such as mesial temporal sclerosis, focal cortical dysplasia, benign intracerebral tumors, arteriovenous malformations and cavernous angiomas, researchers have recently noted other pathologies, such as, encephalocele. There are a number of publications on the connection between epilepsy and cerebral venous angiomas. However, there are no published cases of the influence of the abnormal structure and location of normal cerebral vessels on the development of epilepsy. This article presents a case of an atypically large and unusually located vein of Labbe that may have been involved in epileptogenesis and also complicated an anteromedial temporal lobectomy. Forced coagulation and excision of the Labbe vein during surgery did not lead to venous infarction and neurological deficit.
