Аннотация
CONTEXT: Osteosarcoma is the most common malignant bone tumor in children and adolescents and possesses a high potential for metastasis. The most common sites of osteosarcomatous metastases are the lungs, pleurae, and bone; the pancreas being extremely rare.
CASE REPORT: We report the computed tomography findings of a rare case of pancreatic metastasis in a 14-year-old boy with primary vertebral osteosarcoma being followed-up for 6 years. On abdominal CT, a huge mass containing necrotic and calcified areas and causing bone destruction was seen between thoracic vertebra 7 and sacral vertebra 1 involving both the vertebrae and paravertebral soft-tissue. A large metastatic mass with an irregular contour was also visualized in the pancreatic head and peripancreatic region having tomographic findings similar to the vertebral mass. Tru-cut biopsy of the pancreatic mass confirmed the diagnosis of osteosarcoma metastasis.
CONCLUSIONS: Although extremely rare, osteosarcoma metastasis should be included in the differential diagnosis of pancreatic mass lesions, particularly in patients with a primary tumor.
