Isolated Unilateral Adduction Paresis of the Right Eye Due to a Contusion in the Subnucleus of Oculomotor Nerve.

In this report we present a 45 year old man with horizontal diplopia following minor head trauma. Neurological examination was normal except for unilateral adduction paresis of the right eye. Brain magnetic resonance imaging (MRI) revealed a contusion area 7 mm in diameter at the inferiorposterior portion of the mesencephalon. We thought that this contusion affected the sub-nucleus of oculomotor nerve and caused isolated adduction paresis of the right eye. This relatively rare entity is discussed in the light of the available literature.

Idiopathic Normal Pressure Hydrocephalus Accompanied by Seizure: A Case Report.

The clinical features of idiopathic normal pressure hydrocephalus (iNPH) are characterized by cognitive impairments, gait disturbances, and/or urinary incontinence. These symptoms can also include seizures following a shunt placement but there is a lack of data regarding seizures as a presenting symptom in patients with iNPH. Thus, the present report describes a case of iNPH accompanied by seizures which resolved after the placement of a shunt.
