Imaging Review of Skeletal Tumors of the Pelvis—Part I: Benign Tumors of the Pelvis
Figure 6
8-year-old male presented with left hip pain, diagnosed as Aneurysmal bone cyst. Plain film (a) demonstrates large expansile lytic lesion (arrows) involving medial left acetabulum extending to the inferior pubic rami (G: gonadal shield). Axial CT scan (b) obtained immediately following curettage and packing with bone allograft showing relatively dense material (asterisk) within the expanded left Ischium. Follow-up plain film (c) five years postsurgical curettage and embolization (note the embolization coils along the medial aspect of the hip) shows healing of the ABS with return to normal contour and course trabeculation. Unfortunately, a focus of recurrence is also noted in the superior acetabulum (asterisk). Local recurrence is not common, but possible.
