PDFAbstract
Objective To explore MRI and radiography feature of bone eosinophilic granuloma. Materials and Methods 13 patients with pathologically-confirmed bone eosinophilic granuloma were retrospectively analyzed,Imaging findings, including MRI (n=13) and plain film (n=8). Results There were 4 focuses located in skull,1 in vertebrae, 1 in clavicle, 2 in pelvis and 5 in long bone. all lesions presenting as round or oval osteolytic destruction without dead bone, 4 lesion in skull presenting as penetrativity osteolytic destruction, 3 lesions in in long bone and 1 lesions in clavicle accompanied peroisteal reaction, 1 lesions in in long bone and 1 lesions in clavicle accompanied border sclerosis,1 lesion presenting as expansively osteolytic bony destruction. On MRI, the lesion more showed lightly low-signal on T1WI, while lightly high-signal on T2WI, on STIR, around with high-signal edema and soft tissue offended,from gently to marked enhancement after Gd-DTPA injection. Conclusion EG often finded in children and teenagers, X-ray and MRI of Eosinophilic granuloma all showed characteristic imaging features,depends on the combination of clinical signs and symptoms may to make accurate diagnosis, the final diagnosis still depends on pathology.
