Mesothelial cyst complicated by torsion: preoperative imaging evaluation.

The diagnosis mesothelial cyst is infrequently made pre-operatively, because of the relative rarity of this lesion as a cause of distinct abdominal complaints and a lack of definitive diagnostic tests. A case of a mesothelial cyst complicated by ileal torsion evaluated preoperatively by various imaging modalities, including plain radiographs, ultrasound, computed tomography and enteroclysis studies is presented. It was shown that appearances on enteroclysis significant aided the differential diagnosis, by preoperatively defining the cause of clinical presentation and the extent and degree of the intestinal involvement.
