Reason: Gastric cancer, OSH bony lesions on PET Scan and supposedly negative Bone scan. Needs MRI to further w/u bone lesions. History: weight loss. The imaged musculature of the pelvis is normal in appearance. There is a small right-sided fat-containing inguinal hernia. Although this examination was not protocoled for detailed evaluation of the pelvic viscera, no acute abnormality is identified. Note is made of multiple foci of decreased signal abnormality within the iliac bones bilaterally as well as within the right acetabulum and superior pubic ramus which are associated with cortical thickening corresponding to the findings of suspected Paget's disease seen on recent CT examination. Otherwise no bone marrow signal abnormality is identified. There are no enhancing lesions to suggest osseous metastatic disease. Severe degenerative disc disease affects the imaged lower lumbar spine.
Findings indicating Paget's disease affecting the bones of the pelvis as described above. No convincing osseous metastases are identified.
