Parinaud's syndrome in aqueduct stenosis: its mechanism and ventriculographic features.

Abstract

The expansion of the suprapineal recess which occurs in aqueduct stenosis receives only passing mention in most radiological discussions of the subject (Davidoff and Epstein, 1950; Schechter and Zingesser, 1967; Taveras and Wood, 1964). Three cases have been reported at length (Lavender and DuBoulay, 1965), mainly for the ventriculographic interest. This report points up the local effect of the distended suprapineal recess, the resulting specific symptom of vertical ocular paresis, not hitherto associated with aqueduct stenosis, and the ventriculographic features. Clinical features. A nine-year-old girl was admitted because of headache, vomiting and clumsiness of movements. During severe measles at the age of five years, and again during mumps at the age of six, “encephalitic” manifestations had been noted. In the past year she had complained of headaches while, in recent months, clumsiness of movements, culminating in insecure gait in the last week had become evident. Two days before admission, she first...
