Fig. 22From: Skeletal involvement in Langerhans cell histiocytosisa Coronal CT scan (22a) demonstrates an osteolytic lesion in the metaphysis of the right femur, without involvement of the epiphysis. Note the persistence of tiny bone fragments within the lesion. b Coronal unenhanced T1- and (c) fat-suppressed gadolinium-enhanced T1-weighted MR images show non-specific but extensive signal intensity changes within the bone marrow and the adjacent soft tissues as well as reactive synovitisBack to article page
