Abstract

Seconnday aneurysmal bone cyst is the disease that occurrs in the primary bone tumor and/or tumorus conditions Meticulous search is needed to make a correct diagnosis which dose not overlook the primary diseases. We have experinced an osteolytic lesion on the 7-year-old boy on his skull bone. Plain radiography of the skull revealed osteolytic lesion in the parieto-occipital bone. On the T1 weighted MR image, the lesion revealed multiseptated and the various fluid-fluid levels. Histologically, it showed typical Langerhans` cell histiocytosis which were positive for S-100 protein. In area it also noted typical aneurysmal bone cyst. This report deals with rare Langerhans` cell histiocytosis with secondary aneurysmal bone cyst and discusses its pathophysiology
