OCULOMOTOR NERVE NEURINOMA - EARLY DETECTION BY MAGNETIC-RESONANCE-IMAGING

A case of intracranial oculomotor nerve neurinoma arising in the inter peduncular fossa presented over the course of a year as an oculomotor nerve palsy. Although computerised tomography and pre-contrast magneti c resonance imaging were negative, post-contrast magnetic resonance im aging revealed the tumour which was less than 1 cm in maximum diameter . The tumour was safely removed on the basis of magnetic resonance app earances. This case emphasises that magnetic resonance imaging is usef ul in the detection of such lesions at an early stage of their develop ment.
