We describe a case of relapsed granulomatosis with polyangiitis (Wegener's) (GPA) that presented with abdominal pain. (18)F-fluoro-2-deoxy-D: -glucose positron emission tomography (FDG-PET)/computed tomography (CT) clearly depicted an inflammation of the left peri-iliac arterial soft tissue, which was thought to be the cause of the ureteral obstruction and hydronephrosis. Our case shows that peri-iliac arterial inflammation occurs in GPA and causes hydronephrosis. In addition, FDG-PET/CT is a useful tool for management of this systemic inflammatory disease.

An 8-year-old boy with history of embryonal rhabdomyosarcoma resected 2 years ago presented with abdominal pain and elevated pancreatic enzymes. Acute pancreatitis was diagnosed, and appropriate therapy was started. An FDG PET/CT scan revealed a hypermetabolic region in the pancreas suspicious for malignancy; however, the patient's condition improved after therapy. A repeat PET/CT scan performed 3 weeks later for recurrent symptoms showed interval disease progression, consistent with metastatic disease. Our case indicates that pancreatitis can accompany malignancy or be related to the obstruction caused by tumor, and patient's response to therapy for acute pancreatitis does not rule out malignancy.

A38 -year-old man complaining of abdominal pain was diagnosed with small intestinal cancer. Small intestinal endoscopy and PET-CT showed a primary jejunal cancer and five peritoneal metastases. Partial resection of the jejunum with three metastases was performed, but the others were unresectable. After surgery, FOLFOX chemotherapy was adapted. Follow-up pelvic CT showed a remarkable reduction of tumor size during FOLFOX chemotherapy after 4 courses, and follow-up PET-CT showed no tumor intake FDG after 10 courses. We judged him to be a complete response and stopped chemotherapy. After 7 months, the patient's level of tumor markers elevated, and there was recurrence. We resumed FOLFOX, and the chemotherapy for this patient is still being continued.

Inflammatory myofibroblastic tumors are rare, especially in the pancreas. It is sometimes difficult to obtain a definitive diagnosis with radiological imaging and there is not yet consensus about treatment. We report a case of a 56-year-old man with recurrent abdominal pain particularly in the right upper quadrant without other symptoms. The imaging results showed a pancreatic hypovascularized mass with stenosis of the main pancreatic duct and the common bile duct without metastasis. The FDG PET scanner showed two hypermetabolic foci in the head of the pancreas. The biopsies of the mass were not diagnostic. The therapy adopted was Whipple's pancreaticoduodenectomy with a histological diagnosis of the inflammatory myofibroblastic tumor.

A 19-year-old girl presented with lower abdominal pain. Pelvic ultrasound showed a large cystic mass in the pelvic cavity, and CA19-9 was markedly elevated. On further evaluation, (18)F-FDG PET/CT showed heterogeneous, localized FDG uptake with a central photon defect in the pelvic cavity, and most intense FDG uptake was noted in the anterior portion of lesion adjacent to the ileum. Corresponding enhanced CT showed a cystic mass abutting the ileum with wall thickening. Laparoscopic resection was done and the histologic result was adenocarcinoma arising in Meckel's diverticulum.

Labeled leukocyte scintigraphy and (18)F-FDG PET are well-documented techniques for the assessment of inflammatory bowel disease. In this study, a 28-year-old man with abdominal pain, vomiting, and raised serum amylase and lipase levels underwent PET/CT imaging using FDG-labeled autologous leukocytes to assess for pancreatic infection. While the pancreas showed no abnormal tracer uptake, colonic inflammation was incidentally detected, and a diagnosis of pseudomembranous colitis was subsequently confirmed on colonoscopy and biopsy.

A 43-year-old male patient with follicular B-cell lymphoma was referred for a FDG PET/CT scan due to severe left lower abdominal pain to rule out recurrent cancer. These FDG PET/CT images and previous FDG PET/CT images 5 months ago both revealed an air bubble in the urinary bladder on the CT images. He had a recurrent urinary tract infection history for 6 months. A list-mode dynamic data acquisition with diuresis intravenous injection revealed linear FDG activity extending from the upper-left portion of the bladder to a soft tissue mass in the lower-left pelvic region. An enterovesical fistula was confirmed by surgery.

A 7-year-old girl with a 1-month history of diffuse abdominal pain underwent an ultrasound which showed a pelvic mass with multiple peritoneal implants and ascites. An US-guided core biopsy of one of the implants as well as a transrectal biopsy of the pelvic tumor showed pathological findings consistent with epithelioid mesothelioma. We describe the findings on (18)F-FDG PET/CT in pediatric peritoneal mesothelioma.

A 37-year-old man presented with left upper abdominal pain for 13 months. Laboratory examinations showed elevated peripheral eosinophils. Chest CT showed thickened wall of the entire esophagus. FDG PET/CT was performed showing diffuse FDG uptake in the thickened esophageal wall. Esophageal endoscopy showed pale and edematous mucosa. Histologic examination of the esophageal biopsy specimens revealed marked eosinophil infiltration of the mucosa. The clinical and pathologic findings were consistent with eosinophilic esophagitis (EoE). This case indicates EoE should be included in the differential diagnosis of abnormal FDG accumulation in the esophageal wall along with malignant and nonmalignant conditions.

We describe the case of a 78-year-old man presenting with abdominal pain and a weight loss of 5 kg over 2 months. Colonoscopy and abdominal CT suggested colon cancer of hepatic flexure. F-FDG PET/CT scan showed moderate FDG uptake lesion at the hepatic flexure colon and multiple foci of FDG accumulation in the liver. These were considered as colon cancer with multiple hepatic metastases. However, the pathologic finding of colonoscopic biopsy and CT-guided liver biopsy showed only eosinophilic infiltration and no evidence of malignancy.
