Abstract

Stereotactic radiosurgery is a controversial treatment modality in the management of cerebral cavernous malformations (CVMs). Systematic pathological studies of irradiated specimens probably could help to resolve the controversy. Light microscopic investigation of a surgically resected thalamic CVM 1 year after 40-Gy irradiation revealed endothelial cell destruction in the cavernous channels, and marked fibrosis with scar tissue formation in the connective stroma of the lesion. These histopathological findings were similar to those described in arteriovenous malformations after Gamma Knife surgery, and suggest that the ionizing effect of radiation energy evokes vascular and connective tissue stroma changes in CVMs as well.
