الوصف: Mesenteric masses can considerably shift positions between fractions of radiation therapy (RT). With image-guided RT, we can adapt our treatment delivery daily to target the mass while avoiding surrounding structures. We report the case of a highly-mobile mesenteric mass which required adaptive planning from a traditional “butterfly” intensity modulated radiation therapy (IMRT) plan to an anterior “rainbow” beam arrangement to permit shifting of the isocenter without compromising target coverage or increasing dose to organs-at-risk.

الوصف: Purpose To describe the imaging presentation of carcinoid tumors of the small-bowel at 64-section CT-enteroclysis and determine the sensitivity of this technique for tumor detection. Patients and methods The 64-section CT-enteroclysis examinations of 22 patients with histopathologically proven small-bowel carcinoid tumors and those of 6 patients with suspected recurrence after small-bowel resection for carcinoid tumor were reviewed. Images were analyzed with respect to imaging presentation. Sensitivity, specificity, and accuracy, of 64-section CT-enteroclysis for the diagnosis of carcinoid tumor of the small-bowel were estimated with 95% confidence intervals (CIs). Results Twenty-five carcinoid tumors were confirmed in 22 patients (prevalence, 22/28; 79%). Overall sensitivity for carcinoid tumor detection was 76% (19/25; 95%CI: 55–91%) on a per-lesion basis. On a per-patient basis, 64-section CT-enteroclysis had a sensitivity of 86% (19/22; 95%CI: 65–97%), a specificity of 100% (6/6; 95%CI: 54–100%) and an accuracy of 89% (25/28; 95%CI: 72–98%) for the diagnosis of carcinoid tumor. Focal small-bowel wall thickening, mesenteric stranding, and mesenteric mass were found in 20/22 (91%), 18/22 (82%) and 15/22 (68%) patients with pathologically confirmed tumors. Conclusion 64-Section CT-enteroclysis shows highly suggestive features for the diagnosis of carcinoid tumor of the small-bowel and achieves high degrees of sensitivity for tumor detection.

الوصف: Carcinoid tumors are rare, slow-growing neuroendocrine neoplasms that are often indolent and may not become clinically apparent until there is a metastatic spread or evidence of carcinoid syndrome. A 44-year-old man presented to our clinic department with a history of previous left colon cancer operation, chronic crampy left lower quadrant pain, mass and severe anemia. A MR scan was obtained which demonstrated a calcified mesenteric mass 12×8×10 cm diameter with surrounding left colon mesenteric infiltration. The liver was normal. A case of ischaemic ileal necrosis is reported. It was associated with elastic vascular sclerosis produced by mesenteric metastases of an ileal carcinoid tumor. It is postulated that intestinal ischaemia may be of more importance in the production of abdominal pain by carcinoid tumors than has been generally accepted, and that it is the result of functional and structural changes in and around the mesenteric blood vessels, caused by substances secreted by the carcinoid tumor.

الوصف: Mesenteric hematoma is an uncommon condition. A 24-year-old man who underwent surgery for retroperitoneal leiomyosarcoma presented 9 months later with upper abdominal mass. Computerized tomography revealed a mesenteric mass in relation to proximal ileum. With a diagnosis of tumor recurrence, exploratory laparatomy was carried out, and the mass was resected out. Histology revealed an organized hematoma.

الوصف: Mesenteric panniculitis is a non-neoplastic, inflammatory process affecting the adipose tissue of the mesentery in adults with slight male predilection. Typical computed tomography (CT) or magnetic resonance imaging (MRI) findings are of either diffuse mesenteric infiltration or nodular mesenteric masses. We encountered a case of mesenteric panniculitis in a 26-year-old woman with the left upper quadrant pain and fullness, in which CT and MRI disclosed a large, ill-defined, multilocular cystic mesenteric mass. After surgery, the diagnosis of mesenteric panniculitis was made. The cystic components were dilated lymphatics due to lymphatic and venous obstruction by the mesenteric panniculitis.

الوصف: Intra-abdominal desmoid tumours represent a major cause of morbidity and mortality in patients with familial adenomatous polyposis (FAP), and such patients are also liable to develop musculoskeletal desmoids. We have reviewed the CT appearances of 44 desmoid lesions (28 intra-abdominal and 16 musculoskeletal) in 20 patients with FAP We found a considerable heterogeneity in the CT appearance of musculoskeletal and intraabdominal desmoids, with respect to their density, definition and change in size or density on follow-up, not only between different patients but also in patients with multiple lesions, who rarely showed identical appearances of all lesions. In some cases, mesenteric tumours may initially present as ill-defined soft tissue infiltration of mesenteric fat, becoming larger and more mass-like with time. On medical treatment, shrinkage was seen infrequently in musculoskeletal desmoids, and not at all with mesenteric lesions. CT evidence of bowel involvement by intra-abdominal lesions was frequent, most commonly appearing as ‘tethering’ or encasement of bowel loops. The presence of a large mesenteric mass (>10 cm diam.), multiple mesenteric masses, extensive small bowel involvement and/or bilateral hydronephrosis were associated with ultimate death.

الوصف: The radiological features of small intestinal lymphoma are described in 11 patients examined using the small bowel enema technique. The signs include luminal narrowing with mucosal destruction and occasionally shouldering of the margins and stricture formation, broad-based ulceration, cavitation, non-specific thickening of the valvulae conniventes, discrete intraluminal filling defects, and a mass. In one patient, small nodules were scattered throughout the small intestine. Aneurysmal dilatation of a segment of intestine was seen in one case and an extraluminal mesenteric mass in another. A combination of different signs was a frequent finding and multiple intestinal lesions were present in four cases. Predisposing factors were present in five cases including coeliac disease, chronic lymphatic leukaemia, immunoproliferative small intestinal (alpha-chain) disease and previous extraintestinal lymphoma. In another patient there was evidence of extraintestinal lymphoma at the time of presentation.

الوصف: Seven cases of arteriomesenteric duodenal compression are presented. Of the four acute cases, three related to spinal scoliosis and one to lordosis. Three cases were of the chronic type, one being due to a mesenteric mass. Roentgenography is the basic diagnostic aid. Surgical intervention was required in four cases.
