title: Colloid cysts in children.
abstract: Three patients with colloid cysts were identified among approximately 1,400 patients with brain tumors seen at the Hospital for Sick Children in Toronto between 1952 and 1992. These and 34 previously published cases of colloid cysts in children were reviewed. Colloid cysts are rare causes of headaches and papilloedema in children. They usually present with chronic headaches and increased intracranial pressure. Although acute deterioration can occur at any time, it is uncommon. A CT scan or MRI with intravenous contrast is necessary to identify them, particularly those which are isodense. The growth, and subsequent postoperative recurrence of a colloid cyst in 1 youth argues for treatment by complete surgical excision in children.
