title: Posttraumatic intradiploic leptomeningeal cyst in an adult: case report.
abstract: We report the case of an adult with a posttraumatic intradiploic leptomeningeal cyst that caused a circumscribed osteolytic skull lesion. Local pain, the only symptom of the lesion, regressed after surgery. Intradiploic leptomeningeal cysts must be distinguished from intradiploic arachnoid cysts, which are of congenital origin.
