UNASSIGNED: BACKGROUND @entity892 is a common subjective complaint that can be the first manifestation of a serious pathology. Here, we report a rare case of midbrain @entity1188 involving the lateral subnucleus of the oculomotor nuclear complex presenting as @entity892 , with no other @entity64 manifestations. CASE REPORT An 83-year-old right-handed white @entity1 with past medical history of @entity6 , @entity101 , @entity2299 , and @entity453 presented to the emergency department (ED) with @entity892 and @entity426 . Two days prior to admission, the @entity1 woke up with constant horizontal @entity892 and @entity426 , which limited his daily activities and led to a fall at home. He denied any @entity425 , clumsiness, @entity390 , @entity391 , @entity3917 , @entity221 , or chills. Ocular exam showed a disconjugate gaze at rest, @entity425 of the left medial rectus muscle, impaired convergence test, and bilateral 3-mm reactive pupils. The @entity892 resolved by closing either eye. The remaining extraocular muscles and other cranial nerves were normal. There was no nystagmus, @entity1736 , or @entity227 . Sensation, muscle tone, and strength were normal in all extremities. Magnetic resonance imaging (MRI) of the brain revealed a tiny focus of restricted diffusion in the left posterior lateral midbrain. CONCLUSIONS A thorough history and physical examination is essential to diagnose and manage @entity892 . @entity912 is usually thought to be caused by orbital lesions or @entity121 . Here, we report a case of midbrain @entity1188 manifested as isolated medial rectus palsy.
