| Abstract |
An isolated dilated and fixed pupil in the absence of other neurological dysfunction usually suggests ciliary ganglion dysfunction or direct pharmacological blockade of the parasympathetic fibers to the pupil. A unilateral dilated pupil as a manifestation of a mesencephalic hemorrhage has not, to our knowledge, previously been reported. We now describe a 35-year-old woman who had a headache and a dilated and nonreactive right pupil. A cranial computed tomography scan showed a small hemorrhage in the midbrain, and a cerebral angiogram was normal. Mesencephalic hemorrhage should be considered in the differential diagnosis of an isolated dilated pupil. |
