Postirradiation necrosis of the temporal lobe presenting as a glioma

Abstract

✓ A patient is reported who presented with manifestations of a space-occupying lesion in the left temporal lobe thought to be a metastasis, but on radiological examination and surgical exploration appeared to be a diffuse infiltrative glioma. Some 21 months earlier he had received a course of fast neutron therapy to a carcinoma of the left parotid gland. Diagnosis by microscopic examination revealed changes characteristic of delayed radiation necrosis.
