case_images: fig1
case_images: Antero-posterior and lateral (Figures 1(a) and 1(b)) X-rays revealed a well-defined eccentric osteolytic lesion in the distal diaphysis of left ulna with expansion of overlying cortex and without calcification.
case_images: T1 W coronal image showed a well-defined low signal ovoid intramedullary lesion measured 2*1 cm in the distal diaphysis of left ulnar bone that was protruding exophytically from medial surface of ulnar bone.

case_images: Histopathology showed a cartilaginous tissue with uniformly sized chondrocytes in a myxoid matrix located in the round lacunae, compatible with enchondroma and with no evidence of cytological dysplastic cell (Figure 5).
