Bilateral Cerebral Ptosis in a Patient with Subdural Hemorrhage: a Case Report.

Although cerebral ptosis is rare, it is commonly associated with unilateral right cerebral hemisphere lesions. We report a case of a 79-year-old woman who presented with bilateral complete ptosis after a traumatic right fronto-temporo-parietal subdural hemorrhage (SDH). Bilateral ptosis was the primary manifestation of the acute right SDH, and the patient had no parenchymal lesion. Her prognosis was good, and she made a complete recovery. Right hemispheric hypoperfusion, as demonstrated on brain perfusion single-photon emission computed tomography, implied that the lateralization of eyelid control was in the right hemisphere, in line with previous reports.
