“…A review of the published English literature revealed just four cases of mediastinal enteric cyst in atypical locations (ie, other than the right posterior mediastinum). Of these four cases, two were left posterior mediastinal masses [3,4]; one was in the middle mediastinum, mimicking a pericardial cyst; and one was in the anterior mediastinum [5,6]. However, although Carr and colleagues [6] reported an enteric cyst in the same position as in our case (ie, anterior mediastinum) in 1977, CT technology was unavailable at that time, and hence diagnosis was not possible.…”

“…Foregut cysts, which include bronchogenic, esophageal, and enteric cysts, make up 18% of all primary mediastinal masses (1). Mediastinal enteric cysts account for only 1-2% of all mediastinal cysts (2).…”

Mediastinal enteric cysts are rare congenital thoracic cysts. The majority of mediastinal enteric cysts occur in infants, while they are rare in adults. Although most of these cysts are benign, surgical resection is sometimes performed, and malignant changes found in enteric cysts are rare. A 52-year-old man was incidentally discovered to have a posterior mediastinal mass and we excised the mass thoracoscopically. Histopathological findings showed an enteric cyst with adenocarcinoma. Comparing the pathological and magnetic resonance imaging (MRI) findings, MRI would help to detect malignant changes in such cysts.Although malignant changes found in mediastinal enteric cysts are extremely rare, clinicians should always keep in mind that those cysts have malignant potential and careful evaluation of MRI would be a clue for surgical indication.

“…3 Approximately 10% of duplication cysts contain ectopic gastric mucosa, usually at the wall of the duplications. [4][5][6] Enteric cysts usually lie in the posterior mediastinum and, in most instances, have no connection with the esophagus. 7 The predominant mechanism of 99m Tc-pertechnetate uptake is specific mucin cell uptake and secretion.…”

A 3-year-old boy presented with intermittent abdominal pain, melena, and anemia since 2 months. Upper gastrointestinal endoscopy did not reveal any significant abnormality. The child was then referred for 99m Tc-pertechnetate scan to rule out the presence of ectopic functioning gastric mucosa. 99m Tc-pertechnetate scan revealed abnormal tracer accumulation in the thoracic region, which persisted in the delayed images, suspicious for being ectopic gastric mucosa. Subsequently, ultrasound and contrastenhanced CT (CECT) scans of the chest revealed a large multiseptate cystic lesion in the retrocardiac region, corresponding to the site of increased tracer uptake on 99m Tc-pertechnetate scan.
