          Abstract

          Benign esophageal lesions occur in various diseases. Barium studies are useful for the evaluation of mucosal surface lesions but provide little information about the extramucosal extent of disease. Computed tomography and magnetic resonance imaging, on the other hand, permit the assessment of wall thickness, mediastinal involvement, adjacent lymphadenopathy, and distant spread. In diseases such as fibrovascular polyps, duplication cysts, scleroderma, trauma, caustic esophagitis, hiatal hernia, esophageal diverticulum, achalasia, and paraesophageal varices, the findings of imaging studies are specific, obviating the need for further invasive diagnostic work-up. The advent of helical computed tomography and its volume data set allows the acquisition of multiplanar images, and magnetic resonance imaging is useful both for this and for tissue characterization. Thus, multiplanar cross-sectional imaging further extends the role of imaging modalities to the evaluation of benign esophageal lesions. Through an awareness of the multiplanar cross-sectional appearances of various benign esophageal lesions, the radiologist can play an important role in the detection, diagnosis, further diagnostic planning, and treatment of the diseases in which they occur.

          Gastrointestinal tract duplications: clinical, pathologic, etiologic, and radiologic considerations.

          Gastrointestinal tract duplications are uncommon congenital abnormalities. By definition, they are located in or adjacent to the wall of part of the gastrointestinal tract, have smooth muscle in their walls, and are lined by alimentary tract mucosa. The lining mucosa is not necessarily that of the adjacent segment of the gastrointestinal tract. The only clinically important ectopic tissues are gastric mucosa and pancreatic tissue. Although ectopic gastric mucosa is found in duplications at all levels of the gastrointestinal tract, it is most prevalent (43%) in esophageal duplications. Peptic ulcer within this ectopic tissue can account for unusual, often misleading symptoms. Ectopic pancreatic tissue is most common (37%) in gastric duplications and is associated with pancreatitis and elevated amylase levels. Detection of associated vertebral anomalies is a helpful clue in the radiographic diagnosis of duplications. Barium studies usually reveal an intraluminal, intramural, or extrinsic mass, and ultrasonography (US) demonstrates its cystic nature. When US findings are inconclusive, computed tomography can be used to show the true nature, location, and extent of the lesion, as well as associated vertebral anomalies and possible other duplications. Technetium-99m pertechnetate scintigraphy provides definitive evidence of a duplication when it contains ectopic gastric mucosa and is particularly useful for suspected esophageal, duodenal, and small bowel lesions.

            Benign schwannoma of the gastrointestinal tract: a clinicopathologic and immunohistochemical study.

            A clinicopathologic and immunohistochemical review was made of 24 cases of distinctive nerve sheath tumors located in the gastrointestinal tract. The tumors were microscopically evident in the presence of peripheral lymphoid cuffing and benign nuclear atypia. The tumors arose in the muscularis propria of the stomach in 23 cases and in the ascending colon in 1 case. The patients included 9 men and 15 women whose ages ranged from 36 to 78 years (average, 58). No recurrence has developed in any patient who underwent resection. Although positive immunostaining for S-100 protein, Leu 7 antigen, and laminin might support the schwannian nature of these tumors, the positive immunoreactivity for glial fibrillary acidic protein (GFAP) indicated the possibility of a myenteric plexus origin. The pattern of S-100 protein immunostaining differed from that seen in cases of gastrointestinal stromal tumors associated with von Recklinghausen's neurofibromatosis or that noted in cases of conventional leiomyomas. We propose that these tumors be designated as benign schwannoma of the gastrointestinal tract.

              Leiomyomata of the esophagus. An analysis of 838 cases.

              Review of the world literature to the end of 1971 has provided data on 838 cases of esophageal leiomyomata, including our own 19 surgically removed lesions. Although esophageal leiomyoma is the most common of the benign tumors of the esophagus, it is still rare compared with carcinoma. It occurs in more men than women, by a ratio of 1.9 to 1. Over 50% of the patients with leiomyoma of the esophagus are asymptomatic. Dysphagia and vague pain are the most frequent symptoms. Pyrosis is mentioned in the literature as present in 40% of the cases, but it is considered mainly as symptom of coexistent hiatal hernia. Diagnostic problems often arise, as the smooth muscle tumors may mimic mediastinal neoplasms, cysts, or even aneurysms, or complicate coexisting hiatal hernia and esophageal diverticulum. Operative management by transthoracic enucleation is the procedure of choice, although resection of the esophagaus may be required in few cases. Postoperative morbidity is minimal and results are excellent.
