Diagnosis: 50 year old female patient with chondrosarcoma
Description: Next to lytic changes deposits of spot-like calcified bone matrix.
A chondrosarcoma is understood as malignant bone tumor that can develop primarily or secondarily, and derives from cartilage tissue.
In the X-ray, one can see an osteolytic tumor with a central calcification. Furthermore, a CT scan, an MRI, and a skeletal scintigraphy are conducted.
As differential diagnoses, bone metastases, enchondroma and other cartiagineous tumors should be considered.
