RESUMO
Nilateral third nerve plasy with bilateral superior rectus paresis and bilateral ptosis is a typical condition for nuclear oculomotor nerve syndrome. In these patients, other neurological examination is normal. We report a rare case nuclear oculomotor nerve syndrome due to midbrain hemorrhage. As a rare cause of intracranial hemorrhage A 59-year-old man presented with an abrupt onset of ptosis and difficulty opening his eyes. He had uncontrolled hypertension in his history. Neurological examination revealed left oculomotor palsy with impairment of bilateral upward gaze and bilateral ptosis. CT scan showed mesencephalic hematoma in superior and left area. It is emphasized that isolated mesencephalic hemorrhage may be the cause of the nuclear oculomotor nerve syndrome without of other associated neurological signs
