title: Protruding arachnoid granulations mimicking dermoid cysts.
abstract: This is the report of two children who had prominent arachnoid granulations that were mistaken clinically for dermoid cysts. These lesions appeared in the midline, primarily posteriorly. During surgery, the lesions extended through the dura connected by a stalk. A pathologic examination confirmed the lesions to be arachnoid granulations.
