The metastatic invasion of pelvic bones is a very frequent event, either in the form of lytic lesions or dense lesions. Generally, the patient suffers from pain of varying intensity, but also from functional impotency and limping.
Lysis can destroy the acetabulum, or an ischiopubic or iliopubic arch, thus preventing walking. An orthopaedic advice is mandatory.
The main radiological observations are illustrated on the diagram below:
On the left side (of the patient): lytic lesion of the iliac bone,
On the following radiography, a mixed aspect (lytic and dense lesions) of pelvic bones can be observed.
Another lytic aspect observed on this X-Ray, concerning a female patient with metastatic breast cancer.
Another typical lyticaspect of pelvis bone concerns a male patient previously operated on for a bladder carcinoma.
