Traumatic Oculomotor Nerve Palsy

Oculomotor nerve palsy generally presents with mydriasis, blepharoptosis, and impairment of extraocular muscle movement. The incidence of primary traumatic oculomotor nerve palsy in craniocerebral trauma is approximately 1.2% [1]. The causes of oculomotor nerve palsy are congenital, traumatic, vascular, migrainous, and parainfectious. Especially in children, it is often caused by congenital fac...

MR of oculomotor nerve palsy.

PURPOSE To assess the utility of MR in third cranial nerve palsy. 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 ...

Intraneural hemorrhage in traumatic oculomotor nerve palsy

Isolated traumatic oculomotor nerve palsy without internal ophthalmoplegia is a rare condition after closed head trauma. The nerve strain leads to intraneural edema with nerve swelling on T2-weighted magnetic resonance (MR) images and traumatic disruption of the blood peripheral nerve barrier with contrast enhancement on T1-weighted MR images. In this patient, susceptibility-weighted MR imaging...
