Glioblastoma Multiforme in the Left Frontal Lobe Subsequent to Malignant Lymphoma in the Right Orbit —Case Report—

Abstract

A 62-year-old male presented with glioblastoma multiforme in the left frontal lobe manifesting as motor aphasia, subsequent to a malignant lymphoma in the right orbit. He underwent subtotal removal of the right orbital mass presenting as right exophthalmos which was shown by histological examination to be non-Hodgkin''s lymphoma. He received 30 Gy Lineac irradiation to the right orbit. His postoperative course was satisfactory. Magnetic resonance (MR) imaging with gadolinium-diethylenetriaminepenta-acetic acid (Gd-DTPA) 7 months later demonstrated a small spotty enhanced lesion in the left frontal lobe. He developed motor aphasia 1 year after irradiation. MR imaging disclosed an enhanced mass in the left frontal lobe, which was totally removed. Histological examination revealed glioblastoma multiforme. Patients with malignant lymphoma may develop a subsequent second malignant tumor. MR imaging with Gd-DTPA is quite useful for early detection of a second brain tumor.
