Clival Metastases Causing Diplopia - An Unusual Presentation of Bronchogenic Carcinoma

Abstract

Lung Cancer is the most common cancer worldwide with most cases being detected at Stage IV. Among these, metastases to the clivus are rare with only very few cases reported in literature. The long course of the abducent nerve in relation to the clivus, makes it susceptible for metastases and subsequent lateral rectus palsy. We present the case of a heavy smoker, 64 years old man who presented with headache and diplopia, on evaluation diagnosed as bronchogenic carcinoma with clival metastases on magnetic resonance imaging(MRI).
