A 36-year-old woman with a 2-week history of fever and markedly elevated lactate dehydrogenase levels. Nonenhanced CT and contrast-enhanced CT showed hepatosplenomegaly, diffusely decreased attenuation of the liver, and homogeneous enhancement in the hepatic and splenic parenchyma. 18F-FDG PET/CT revealed diffuse intense heterogeneous uptake by the liver (like superscan in bone scintigraphy). A liver needle biopsy confirmed the diagnosis of hepatosplenic alphabeta T-cell lymphoma. Subsequently, she received chemotherapy...

An 89-year-old woman presented with seizure and hyponatremia. CT and MRI demonstrated mass-like enlargement of the adrenal glands and multiple pulmonary nodules. PET/CT performed to evaluate for metastatic disease demonstrated intense 18F-FDG uptake within enlarged adrenal glands. Given mild uptake in the pulmonary nodules, the differential diagnosis for the adrenal uptake included lymphoma, granulomatous infection, and less likely, metastatic lung cancer.

Hepatosplenic Gamma Delta T cell lymphoma (γδHSTL) is a rare, highly aggressive, and rapidly lethal T cell lymphoma which manifests 18 F-FDG PET/CT findings that can mimic benign conditions. Patients with γδHSTL present with unexplained symptoms of a hematologic malignancy like the B symptoms of lymphoma including weight loss, fevers, and night sweats, as well as, splenomegaly and hepatomegaly. Thrombocytopenia, anemia, or neutropenia are also common due to spleen, liver and bone marrow involvement. The peripheral blood, however, typically does not show abnormal T cells...

PURPOSE: Primary pancreatic carcinoma and pancreatic metastases are rare in the pediatric population. Pancreatoblastoma is the most common pancreatic malignant tumor in young children and solid-pseudopapillary tumor in teenagers. Pancreatic adenocarcinoma is extremely rare under the age of 40 and is usually associated with underlying genetic abnormalities. Secondary malignancies of the pancreas occur more frequently than primary pancreatic malignancies in children and are most commonly seen with non-Hodgkin lymphomas (NHL) and mesenchymal sarcomas...

BACKGROUND: When subjects without a known malignancy present with suspicious skeletal lesions, differential diagnosis and primary cancer identification is important. Here, we investigated the role of FDG PET/CT in this clinical situation. METHODS: We enrolled 103 patients with no known malignancies who were referred for FDG PET/CT because of bone lesions that were suspicious for cancer metastasis. Each extra-skeletal FDG lesion was categorized as consistent with primary cancer or with metastasis based on the distribution and pattern of all abnormal lesions in the individual...

RATIONALE: Bilateral adrenal diffuse large B-cell lymphoma, nongerminal center B-cell phenotype (non-GCB DLBCL), is an uncommon malignancy that exhibits rapid development. Fluorine-18-fluorodeoxyglucose position emission tomography/computed tomography (CT) is extremely sensitive in distinguishing highly malignant tumors from benign tumors. PATIENT CONCERNS: We report a case of non-GCB DLBCL showing significantly high uptake of 18F-FDG on PET/CT examination. DIAGNOSES: Histopathological and immunohistochemical examination further confirmed that the bilateral adrenal masses were non-GCB DLBCL...

Neoplasms arising from the urachus are extremely rare. We present a case of a young woman with mild abdominal pain and a palpable swelling in the mid abdomen with incidental detection of a subumbilical mass. Repeated fine-needle aspiration cytology failed to reveal the true nature of the lesion. F-FDG PET/CT showed tracer uptake in the cranial end of urachal remnant lesion. Core biopsy from the site with maximal FDG uptake turned out to be lymphomatous involvement in urachus, which is extremely rare and previously unreported...
