A 50-year-old woman presented with upper abdominal pain for 2 months. Abdominal enhanced CT showed multiple hypodense cystic tumors in the liver with heterogeneous enhanced septations. FDG PET/CT showed hypermetabolic peripheral regions and internal septations of the tumors with SUVmax of 6.3. Multiple hepatic cystadenocarcinomas were suspected. The patient underwent resection of the tumors. Epithelial mesothelioma was confirmed by pathology. This case indicates primary hepatic mesothelioma should be added to the differential diagnosis of FDG-avid malignant hepatic tumors.

Common bile duct (CBD) tuberculosis is rare. A 39-year-old woman was referred because of a 5-month history of abdominal pain. Abdominal enhanced MRI and CT showed dilatation of the distal CBD with irregularly thickened wall. Enhanced CT revealed enlarged retroperitoneal lymph nodes. FDG PET/CT showed increased FDG uptake of the CBD lesion and several retroperitoneal lymph nodes with slight FDG uptake. CBD cholangiocarcinoma with retroperitoneal lymph node metastasis was suspected. CBD tuberculosis was confirmed by endoluminal biopsy. Tuberculosis should be considered in the differential diagnosis of abnormal biliary FDG accumulation, particularly in tuberculosis endemic areas.

A 36-year-old female patient with recurrent fever and abdominal pain for 20 days underwent a whole-body FDG PET/CT to detect the potential source of the fever. The images showed intense FDG uptake in multiple bones. Eventually, follicular dendritic cell sarcoma was diagnosed following the biopsy from the lesion in the left iliac bone.

A 62-year-old man received total gastrectomy and splenectomy for gastric cancer in April 2008. The pathological diagnosis was stage IIIA(pT3N2M0). After the surgery, he was treated with oral administration of S-1 as postoperative adjuvant chemotherapy, but stopped after five months because of a drug eruption and general fatigue. He visited our hospital with complaints of abdominal pain and appetite loss in January 2010. Tumor marker(CEA)was elevated, and he was diagnosed as local recurrence with metastasis to the mediastinal/Virchow lymph node and thoracic vertebra after several examinations. He started to undergo combination chemotherapy with CPT-11 and CDDP. After three courses of treatment, local recurrence had almost disappeared and CEA level was normalized. After five courses of treatment, FDG-PET showed that all recurrent tumors had decreased in size and FDG uptake. We finished this combination chemotherapy after ten courses. After the treatment, PET-CT detected a slowly-growing right lung tumor. He received S6 segmentectomy of the right lung in May 2012. The pathological diagnosis was squamous cell carcinoma, and he was diagnosed as primary lung cancer(pT1aN0M0, stage I A). He was followed without showing any recurrence of gastric cancer in October 2012.

Peripheral primitive neuroectodermal tumor (pPNET) is a very aggressive neoplasm that predominantly affects children and adolescents with a poor prognosis. A 35-year-old woman presented with right upper abdominal pain for 2 weeks. Abdominal enhanced CT showed a large cystic-solid tumor in the left retroperitoneum, with progressive enhanced papillary projections of the wall. FDG PET/CT showed strong FDG uptake of the cystic wall with SUVmax of 17.2. The patient underwent completed resection of the tumor. pPNET was confirmed by pathology. The high FDG uptake of the tumor may be related to its high proliferative index revealed by Ki-67.

Mucocele of the appendix is an uncommon condition characterized by luminal distension and accumulation of a mucoid material. Occasionally, it can be caused due to malignancy like cystadenocarcinoma, and the preoperative diagnosis of which is very rare. We report a case of a 64-year-old lady presenting with intermittent abdominal pain diagnosed on ultrasonography as a mucocele where preoperative (18)F-flurodeoxyglucose positron emission tomography/computerized tomography (FDG PET/CT) findings raised a strong suspicion of malignancy. FDG PET/CT findings brought about a change in therapeutic plan, and the patient was considered for a more extensive surgical resection. The final histopathology revealed cystadenocarcinoma as the cause of appendicular mucocele, a finding hitherto undescribed on FDG PET/CT.

Angiosarcoma is rare and highly malignant vascular neoplasm, and primary retroperitoneal angiosarcoma is extremely rare. Preoperative diagnosis is very difficult because there are no specific imaging features, and definitively effective treatment has not yet been established. We recently treated a patient with primary retroperitoneal angiosarcoma in which a prompt and exact diagnosis was difficult to obtain. One month after surgery, local recurrence appeared, but salvage immunotherapy using recombinant interleukin-2 (rIL-2) showed good efficacy, and the patient obtained complete response. Here we report this rare case of angiosarcoma. A 60-year-old woman with abdominal pain was diagnosed with a left retroperitoneal mass on CT scan. The tumor was about 9 cm in diameter and positioned above the left kidney. Further study using MRI, 131I-MIBG scintigraphy, and enhanced CT suggested chronic expanding hematoma and the patient underwent surgical resection. Histopathological diagnosis was primary retroperitoneal angiosarcoma based on positive staining for VIII factor, CD31, CD34, and p53. One month after surgery, FDG-PET revealed local recurrence adjacent to the psoas major. We initiated salvage immunotherapy using rIL-2. The patient was treated effectively and achieved complete response. She is alive and well 19 months after surgery and rIL-2 treatment.

A previously healthy 9-year-old boy presented to an outside hospital with a history of abdominal pain and vomiting. An abdominal x-ray was unremarkable. A CT of the abdomen and pelvis performed to evaluate possible obstruction after weight loss and vomiting over a 3-week period demonstrated a large retroperitoneal mass. Laparoscopic biopsy showed diffuse large B-cell lymphoma. FDG PET/CT was performed for staging. An ileocolic intussusception was identified on the PET/CT. The intussusception was successfully managed with medical treatment. We present FDG PET/CT findings in intussusception with non-Hodgkin lymphoma as the lead point in a pediatric patient.

A 79-year-old woman presented with abdominal pain. Ultrasound revealed an intra-abdominal mass in the left renal region. Comprehensive endocrine workup was unremarkable. The patient was referred for further diagnostic workup. FDG PET/CT revealed a hypermetabolic mass in the left adrenal region. In addition, pathologically increased tracer uptake of 2 renal veins (the upper vein crossing in front of the aorta the lower one crossing behind the aorta) and the inferior vena cava raised the concern for malignant venous infiltration. Adrenalectomy, nephrectomy, and thrombectomy were carefully planned and performed. Adrenocortical carcinoma with tumor thrombus and caval extension was proven by histopathology.

An 81-year-old woman with history of thyroiditis and a putative diagnosis of retroperitoneal fibrosis presented with abdominal pain, progressive shoulder pain, back pain, and lower extremity weakness. Abdominal and pelvic MRI revealed periaortic inflammation and a left renal mass, which were F-FDG avid on PET/CT. Renal biopsy was compatible with immunogammaglobulin 4 (IgG4)-related disease. Total spine MRI revealed postcontrast meningeal enhancement, correlating with FDG activity. Epidural biopsy showed chronic inflammation and scattered but not abnormal IgG4-positive cells, possibly related to posttreatment changes. This case exemplifies multiorgan involvement in IgG4-related disease.
