Abstract
Twenty-eight cases of intracranial arachnoid cysts in children aged 3 months to 16 years (mean 4 years) have been studied and the location of cysts and clinical symptoms were correlated. Twenty-two patients were male, and six were female. In twenty-two patients, the cysts were located in the middle cranial fossa, and there was a higher incidence on the left side (16 case…s86%); 3 in the posterior fossa, and 3 in the convexity.
A rare case of the middle fossa arachnoid cyst was presented. A 6-year-old-boy had proptosis from birth and many cafe au lait spots. The optic fundus was normal, as was visual acuity. Computed tomographic scan showed left parasellar cystic collection with thinning of sphenoid wing and mild proptosis of the left eye.
The other congenital anomalies were associated with arachnoid cysts in nine of 28 cases, which were cutaneous, cardiac, and skeletal disorders. Most frequent clinical symp-toms were convulsions, and delayed motor and mental development
