Skeletal Angiomatosis LSBU

Description: Radiology case 448-3143 Clinical presentation: 83 yr old female with increasing pain and deformity.
The view shows multiple irregular small areas of bone loss, particularly in the pubis on both sides of the pelvis. The pathology extends to the ischium on the right side and into the whole of the ischium on the left side. The superior ramus of the left pubis is distorted and thinned. The body of the right pubis is distorted as if there has been a fracture in the recent past. The lytic areas have a narrow zone of transition between normal and abnormal bone. The density of the adjacent left ilium suggests some involvement near the acetabulum.
The later view shows almost complete resorption of left pubis and ischium. The involvement of right pubis has progessed with additional well-defined defects in the right ischium, adjacent to the right ischial tuberosity. There is deformity of the pelvis with increased protrusio-acetabulae from the initial view. as well as bone destruction. The view of the pelvis is oblique and the appearance of the ilium is ambiguous. Its involvement has progressed and a deformity of the left ilium cannot be excluded in this view.
