Positron emission tomography-computed tomography scan of the patient revealing multiple enlarged lymph nodes in the root of the left side of neck, mediastinum, bilateral hilus of the lungs, right cardiophrenic angle, hepatic portal area, peripancreatic area, diaphragm angle, posterior peritoneum, inter-mesangial area and anterior sacral area, and along the iliac blood vessels, bilateral iliac fossa, pelvic wall and bilateral lingual areas. The scans reveal multiple nodules in the bilateral lungs, an enlarged liver with nodular appearance of the parenchyma, an enlarged spleen with multiple low-density shadows in the parenchyma, and multiple regions of elevated fluorodeoxyglucose metabolism in the bones, such as the sternum, multiple vertebrae, and the bilateral ilia, pubis and ischia. A diagnosis of lymphoma was therefore considered.
