RESUMO

Objective To discuss the clinic and imaging features of solitary enchondroma.Methods Radiography,CT and MRI were performed in 11 cases of solitary enchondroma confirmed by pathology.The imaging findings were retrospectively analysed.Results The tumors in 11 cases localized in metacarpal bone in 3, in bones of fingers in 4, in shaft of humerus in one,in metaphysis of femur in 2 and in metaphysis of tibia in one.Plain radiography showed typical radiographic features including a well defined central lucency in the diaphysis of the metacarpal bones and bones of fingers with calcifications inside the lesions and lobulated contour,the cortex was thinned and cortical expansion also might occur.The lesions appeared as soft tissue density with stippling calcification on CT,low signal intensity on T1WI and mixed mainly high signal intensity on T2WI.A low signal zone around the lesion could be seen on T2WI in one case.Conclusion The qualitative and differential diagnosis of solitary enchondroma can be made mostly by imaging examination.
