Fluctuating Foville's syndrome caused by a pontine angioma in a patient with a polycystic kidney.

摘要

Vascular events are sometimes observed in patients undergoing hemodialysis due to chronic renal failure. If a patient complains of repeated disturbances of eye movement with fluctuation before and after hemodialysis, it suggests the presence of an ischemic stroke due to dehydration. Otherwise it is likely a myasthenic syndrome such as myasthenia gravis. Although intracranial hemorrhage seldom causes a repeated disturbance with fluctuation, an atypical pathogenesis, including angioma-related hemorrhage, sometimes induces a fluctuating disturbance of eye movement.
