However, they are uncommon in children, with an incidence of only 1%. Materials and methods: This is a review of the management of CPA lesions in children admitted to the Hospital Nacional de Pediatría "Profesor Doctor Juan P. Garrahan” (Argentine National Pediatrics Hospital "Professor Juan P. Garrahan”) between January 1988 and December 2003. Results: The series included 30 children with 33CPA lesions, 20 arising from the subarachnoid space of the CPA and 13 from the vicinity and growing mainly into the CPA. Twenty-seven tumors were located in the left CPA (82%) and six (12%), on the right. Ten of the 30 patients developed hydrocephalus, but only three of these required treatment. All patients underwent retrosigmoid suboccipital craniotomy and microsurgical resection. Gross total removal was achieved in 12 cases, subtotal in 18, and fenestration of the cyst wall in the three arachnoid cysts. Ten patients have no sequelae, ten have mild deficit, three have severe deficits, and seven have died. Conclusion: The CPA is a rare location for lesions in children, with clear predominance on the left side. Benign lesions are more frequent. Even though schwannoma is the most frequently found lesion, the histology varies widely.
