Skeletal Metastases from Hepatocelluar Carcinomas: Radiologic Findings
|
|
|
|
|
Abstract
|
|
|
To find any specific radiologic findings of skeletal metastases from hepatocellular carcinoma, we analyzed plain radiographs(n=25), CT(n=16) and MRI(n=5)of 25 patients with metastatic bony lesions from hepatocellular carcinoma. Vertebrae(17/25)
and
rids(16/25)were most frequently involved and 16 cases showed multiple metastases. The size of the lesions was larger than 5cm in 17 cases. Plain radiographs showed osteolytic destruction(2/25). CT(n=16) showed osteolytic destruction with an
isodense
expansile mass in all cases. Focal low attenuations suggesting necrosis were found in 2 cases. Calcification within the mass was not detected. MRI(n=5) showed a slight hyperintense area on T1WI and a defimte hyperintense mass on T2WI. After
gadopentetate dimeglumine enhancement. The mass showed irregular enhancement.
We concluded that skeletal metastatic lesions from hepatocellular carcinoma showed relatively large osteolytic destruction accompanying soft tissue mass and minimum central necrosis.
