Summary
Primary liver carcinosarcoma, a rare cancer, was diagnosed in a patient presenting with back pain. Bone scintigraphy revealed unusual activity within the liver mass, aiding diagnosis.
Area of Science:
- Oncology
- Radiology
- Pathology
Background:
- Primary liver carcinosarcoma is an extremely rare hepatic malignancy.
- Few cases have been documented, with limited imaging data available.
Purpose of the Study:
- To report a rare case of primary liver carcinosarcoma.
- To describe the diagnostic imaging findings, including novel use of bone scintigraphy.
Main Methods:
- Case presentation of a 69-year-old male with right upper abdominal mass.
- Diagnostic imaging included abdominal ultrasonography, labeled erythrocyte imaging, technetium-99m nanocolloid liver-spleen scan, and technetium-99m methylene diphosphonate (MDP) bone scintigraphy.
- Post-surgical histopathological examination confirmed carcinosarcoma.
Main Results:
- Physical examination revealed hepatomegaly and a giant liver mass.
- Ultrasonography showed a complex solid mass with cystic areas.
- Bone scintigraphy demonstrated heterogeneous, dense activity accumulation within the liver mass, suggestive of osteoblastic activity.
Conclusions:
- Primary liver carcinosarcoma is a rare diagnosis with distinct imaging characteristics.
- Bone scintigraphy can reveal osteoblastic activity in liver carcinosarcoma, aiding in its characterization.
