Mesenteric vascular insufficiency should be suspected in patients with a history of abdominal pain, marked weight loss and significant atherosclerosis. Selective mesenteric angiography is essential and should be used early in the work-up studies of such patients. To ensure clinical correlation, there should be significant occlusion demonstrated in two of the three major mesenteric arteries. Four patients studied extensively for an intra-abdominal neoplasm had occlusive disease of the mesenteric artery demonstrated by arteriography. Elective surgical revascularization of the intestine successfully corrected the problem.

We report a case of a 37 year old man who presented with vomiting and colicky abdominal pain and who was found to have microscopic haematuria. Radiological-examination showed a right hydronephrosis apparently caused by a paracaecal tumour extending to involve the right ureter. This was resected and proved histologically to be a mesenteric fibromatosis. The patient has none of the factors predisposing to the development of this lesion, in particular Gardner's syndrome. Eight months following surgery he appears to have made a full recovery. Previous publications on this rare intra-abdominal neoplasm are reviewed.

18F-fluorodeoxyglucose positron emission/computed tomography (18F-FDG PET/CT) imaging, an established procedure for evaluation of malignancy, shows an increased 18F-FDG uptake in inflammatory conditions. We present three patients with abdominal pain and weight loss. Conventional imaging studies indicated that abdominal neoplasm and 18F-FDG PET/CT for assessment of malignancy showed multiple lesions with intense 18F-FDG uptake in abdomen of the three cases. However, the three patients were finally diagnosed with multi-site abdominal tuberculosis (TB). Of them, two were diagnosed with TB by pathology, one was diagnosed with TB clinically. They recovered after anti-TB therapy. Few reports on accumulation of 18F-FDG in abdominal TB are available in the literature. A high index of suspicion is necessary to achieve an early diagnosis and a better outcome of the disease.

We report a classical presentation of trichobezoar in an 8 year old girl who was referred for consultation querying a probable abdominal neoplasm in the left upper quadrant. A large mobile mass was palpable in the left upper quadrant extending toward the umbilicus. Of note, she also had symptoms of recurrent abdominal pain, nausea, vomiting and halitosis. Although a rare occurrence, trichobezoar must be considered as a differential diagnosis in a patient who had a history of pica, presenting with an abdominal mass.

We report the case of a 22-year-old man who presented with a 3-day history of watery diarrhea, abdominal pain, and fever. An image of the abdomen showed a heterogeneously echogenic mass lesion in the pelvis. The results of the blood cultures performed on admission showed the presence of Morganella morganii. Computed tomography-guided tube drainage was performed, and a culture of the drained abscess fluid yielded M. morganii growth. Exploratory laparotomy with segmental resection of the jejunum and excision of the tumor was performed. Pathological examination showed a gastrointestinal stromal tumor (GIST). A GIST abscess caused by M. morganii was diagnosed on the basis of radiological, microbiological, and histopathological findings. The possibility of an infected GIST should be considered during the differential diagnosis of patients with suspected abdominal neoplasm and bacteremia.

Gastrointestinal stromal tumours are a rare form of intra-abdominal neoplasm derived from mesenchymal tissue, typically presenting with abdominal pain, anaemia or bleeding into the bowel or abdominal cavity. Hypercalcaemia is an unusual complication, having been documented in only seven previous patients, all of whom had advanced metastatic disease. We present a case of treatment-resistant hypercalcaemia in a patient with non-metastatic gastrointestinal stromal tumour, which resolved following excision of the tumour.
