Oculomotor nerve schwannomas are extremely rare tumors, these are usually symptomatic. A 29 year aged male presented with diplopia and blurring of vision in left eye and found to have an extra-axial lesion at left cavernous sinus involving oculomotor nerve. The excised tumor showed classic morphology of a schwannoma. Postoperatively patient developed complete oculomotor nerve palsy. The tumor recurred after 2 years.
