ECCENTRIC SIMPLE BONE-CYSTS OF THE FEMORAL-NECK IN ADULTS

The purpose of this communication is to describe atypical simple bone cysts of the femoral neck seen in adult patients. Two patients, aged 5 6 and 49, having cystic lesions which did not conform to a typical sim ple bone cyst, are reported. Common features including eccentric locat ion, and thick lining tissue and sclerotic margin are not those of typ ical simple bone cysts seen in children. Local mechanical characterist ics might be related to the atypical presentations. (C) Elsevier Scien ce Inc., 1997.
