METHODS We reviewed precontrast and postcontrast MR of 50 patients with third cranial nerve palsy. RESULTS MR demonstrated an appropriate lesion in 32 cases. Of these patients, 6 had brain stem lesions and 15 had involvement of the nerve in the cavernous sinus; lesions of the cisternal segment of the nerve were present in 11 Dysfunction of the third cranial nerve (oculomotor nerve) can result from lesions anywhere along its path between the oculomotor nucleus in the midbrain and the extraocular muscles within the orbit. Most of the lesions causing nuclear third cranial nerve palsy are due to dorsal midbrain infarction and commonly result in bilateral ocular symptoms. These tend to be small lesions with few Third cranial nerve disorders can impair ocular motility, pupillary function, or both.

It is responsible for the movements of four of the six extraocular muscles, the other two being innervated by the trochlear and abducens nerves. The oculomotor nerve sends motor fibers to the levator muscles of the eyelid and to the superior rectus, inferior rectus, and inferior oblique muscles of the eye. It also sends parasympathetic efferents (via the ciliary ganglion) to the muscles controlling pupillary constriction and accommodation.
