✦ Synopsis

Clinical information

A 12-year-old white girl was referred to our institution because of a pathological fracture of the right humerus following a minor trauma of the arm. Radiographs showed that a probable subacute transverse fracture had occurred in a multiloculated, septate, osteolytic lesion of the mid-shaft of the humerus with moderate osseous expansion and periostitis (Fig. ).

Physical findings revealed a palpable tenderness over the right humerus.

Laboratory investigations were unremarkable. Computed tomography (CT) of the right arm demonstrated the presence of multilocular cystic spaces situated in the thickened cortical bone, but no cortical rupture or soft tissue mass was noted (Fig. ). A technetium-99 MDP bone scan showed moderate transverse increased uptake of the radionuclide in the right arm in relation to the fracture. Magnetic resonance (MR) imaging of the same region was performed with SE T1-and GRE T2-weighted images in axial and coronal planes (Fig. ). MR images showed an expansile, lobulated lesion situated in the cortical bone and a small round lesion situated in the medullary portion of the proximal humerus. The lesions had a low signal on T1-and a bright signal on T2weighted images. No enhancement
