title: Bitemporal hemianopia caused by metastatic carcinoma in a patient with Wegener's granulomatosis: an unexpected finding.
abstract: Metastatic lesions in the suprasellar region are extremely rare. The differential diagnosis of a focal lesion at this site is wide ranging and lesions often have a similar radiological appearance. We present a woman with known Wegener's granulomatosis who lost vision while on medical treatment for a presumed granuloma at this site. Exploration revealed a metastatic carcinoma of unknown origin. Attention is drawn to the importance of making a histological diagnosis in cases of suprasellar lesions.
