CT remains the optimal imaging modality for diagnosing cystic and solid masses in the mesentery. CT may provide important information regarding the lesion? location, size and shape, the presence and thickness of a wall, the presence of septa, calcifications or fat, and the involvement of adjacent structures. Although percutaneous imaging-guided or surgical biopsy is often necessary to guide medical management, analysis of the CT features along with the clinical history may be helpful in differentiating mesenteric masses, including cystic lesions and primary neoplasms arising from the mesenchymal tissues or the secondary metastatic lesions. CT is useful not only for detecting cystic and solid mesenteric masses, but also for helping physicians become familiar with the features of various mesenteric masses for accurate diagnosis and treatment.

PURPOSE: Mesenteric and omental cysts are uncommon lesions found all age groups. They elicit interest because of their unclear pathogenesis and confusing terminology. MATERIALS AND METHODS: CT findings of 12 case with mesenteric and omental cysts were described and compared with surgical and pathologic findings. RESULTS: In mesenteric and omental cyst, the histologic diagnoses were lymphangioma(7 cases), nonpancreatic pseudocyst(3 cases), mesothelial cyst(2 cases). Lymphangiomas were usually multiloculated with enhancing wall, located in the small bowel mesentery. And these cystic lesions were frequently attached to bowel and required resection of a bowel segment. In three cases of pseudocyst, thick and enhancing wall was shown in unilocular cyst. Two cases of mesothlial cyst were located in greater omenturn, showed very thin wall in unilocuation. CONCLUSION: The CT features of the mesenteric and omental cysts are fairly characteristic. Identification of lymphangioma, which shows a multilocuation and enhancing wall, is important due to frequent bowel resection in operative field.

Retrospective investigation was performed on 16 patients with lymphoid tumor in mesentery operated in Viet Duc Hospital from 1991 to 2001. Diagnosis signs of clinical value included: abdominal pain (93%), loss of body weight (56,2%), tumor palpable in abdomen (75%), mobile tumor (58,33%). 12/16 patients undergo an ultrasonic examination and in 4/12 ganglion tumor, 2/12-mesenterial tumor, 6/12 undefined tumor in the abdomen were detected. The operation must be considered to solve the complications (11/16 patients) and determine the phase of disease. Once the result of pathological anatomy is concluded, a post-operation chemiotherapy must be realized systematically

Post-traumatic intestinal stenosis (PIS) is an uncommon sequela of blunt abdominal trauma, in which injury to the mesentery or bowel wall leads to focal ischemic stricture of that segment. We present a case of PIS of the ileum diagnosed on the basis of radiological studies and surgical and pathologic findings in a patient with partial small bowel obstruction occurring five weeks after blunt abdominal trauma.

Mesenteric fibromatosis is an uncommon benign neoplasm occurring in the mesentery or retroperitoneum, and presenting as a firm mass with infiltrative margins and homogeneous parenchyma without necrosis or a cystic component (1-4). Cystic change may occur, usually after prolonged medical treatment, but is extremely rare (5-7). We describe the US and CT findings in a case of mesenteric fibromatosis with spontaneous extensive cystic degeneration.

A primary tumor of mesenteric origin is rare. We encountered a malignant gastrointestinal stromal tumor (GIST) of mesenteric origin that demonstrated severe necrosis, and report the CT findings and review the literature.

Extra-adrenal abdominal paragangliomas are rare. Most arise from the organs of Zuckerkandl, involve large concentrations of paraganglionic tissue, and are located in the para-aortic space along the sympathetic chain. Published reports have, however, described normal paraganglionic tissue at the root of the mesentery which serves as the superior limit of the organs of Zuckerkandl, and mesenteric paraganglioma is very rare. We report a case of paraganglioma with cystic degeneration arising from the mesentery.

Anatomical plane and fascia have been described in medical behaviors for hundreds of years since the appearance of anatomy and operation. Generally, these descriptions can be sorted into three theories, i.e. plane surgery, fascia theory and mesentery anatomy. However, these theories are difficult to satisfy the scientific paradigm that includes consistency in description, independence in validation, potential to solve practical problems, and the interaction of the above-mentioned theries. Recently, membrane anatomy was proposed as the anatomy of mesentery and its beds in broad sense. Behind it lies fascia membrane/serous membrane structure, as well as inherent life events and general order. Mesentery in broad sense is described as the fascia membrane/serous membrane in serous cavity, which envelops and suspends the organ/tissue and its feeding structures to the posterior wall of the body. Anatomy is the setting/structure, in which life events/functions occur. In the research and discussion of membrane anatomy, abiding by the scientific paradigm and upholding the scientific spirit are the only way to obtain reliable knowledge and the criterion for in-depth scientific research.
