True intramural esophageal duplication cyst

الملخص EN

Esophageal duplication is the second most common site of gastrointestinal duplication and most cases present with complications.

These complications include bleeding, infection, dysphagia, and dyspnea.

We report an incidental case of a true intramural esophageal duplication cyst in a new military recruit.

The patient was diagnosed in Armed Forces Hospital, Oman.

The patient came for a pre-recruitment routine check-up, he was found to have a suspicious soft tissue lesion on chest X-ray.

He was referred to the thoracic surgeon for further investigations.

The investigations included computed tomography and magnetic resonance imaging chest scans, barium swallow, endoscopy and, finally, an endoscopic ultrasound.

All workup pointed to a diagnosis of esophageal duplication cyst; therefore, the decision was made to excise the lesion after discussion with the patient about the possible diagnosis and nature of the treatment.

The cyst was completely excised thoracoscopically with uneventful recovery.

The patient was discharged a few days later and was doing well in subsequent visits to the outpatient department.

The histopathological exam confirmed the diagnosis of a true congenital duplication cyst, which was lined by pseudostratified ciliated columnar epithelium overlying double layers of thick bundles of smooth muscle fibers
