Malignant schwannomas are rare. These malignomas are primary nerve sheath tumors that usually arise from a peripheral nerve. They appear most frequently in the lower extremities, including the hips and buttocks (34.8%), the upper extremities (23.4%), and in the trunk (17%). To the best of our knowledge, this is the first reported case of a malignant schwannoma of the rectum. We describe the rare disease with reference to the literature.

Intimointimal intussusception is a rare type of aortic dissection. The intimal tear occurs circumferentially with intussusception of the intimal flap downstream into the aortic arch causing obstruction of the great supraaortic vessels. A CT diagnosis has only once been reported. CT and angiographic findings of this rare complication of aortic dissection are described.

A rare case of dysphagia caused by leiomyomatosis of the esophagus is presented. Esophageal leiomyomatosis is triggered by diffuse proliferation of smooth muscle cells in the wall of the entire esophagus. Only 1.0% of all tumors of the esophagus are benign lesions; 0.4% of all esophageal neoplasms are leiomyomas. Only a few cases of leiomyomatosis-a special form of diffuse leiomyomas-have been described so far in the literature. Modern diagnostic imaging techniques such as CT and MR are described in esophageal leiomyomatosis.
