BITEMPORAL HEMIANOPIA CAUSED BY METASTATIC CARCINOMA IN A PATIENT WITH WEGENERS GRANULOMATOSIS - AN UNEXPECTED FINDING

Metastatic lesions in the suprasellar region are extremely rare. The d ifferential diagnosis of a focal lesion at this site is wide ranging a nd lesions often have a similar radiological appearance. We present a woman with known Wegener's granulomatosis who lost vision while on med ical treatment for a presumed granuloma at this site. Exploration reve aled a metastatic carcinoma of unknown origin. Attention is drawn to t he importance of making a histological diagnosis in cases of suprasell ar lesions.
