Rapid growth in a cavernoma

Abstract

The availability of magnetic resonance imaging has greatly increased the detection of cavernous malformations of the central nervous system in both symptomatic and asymptomatic patients. These lesions may be responsible for previously unexplained neurological events or may even have been incorrectly diagnosed. We describe a patient presenting with focal neurological signs in whom an initial diagnosis of malignant glioma had been made. Following excision, the pathological diagnosis was cavernoma. This vascular lesion has continued to show rapid growth and aggressive behaviour despite multiple surgical resections. The indications for operative and non-operative intervention will be discussed.
