Double esophageal duplication cysts: A rare case report in Nicaragua

This is the authors' abstract. We don't add key points for this paper.

Esophageal duplication cyst is a rare congenital anomaly arising from the posterior primitive foregut, typically located in the thoracic esophagus. Herein, we reported the case of a female newborn who was prenatally diagnosed with congenital diaphragmatic hernia. A subsequent computed tomography scan revealed an intact diaphragm and a large septated cyst measuring 132×59×41 mm with a volume of 120 mL, situated extrapleurally near the right paravertebral area. Surgical intervention involved a right thoracotomy under general anesthesia to remove the larger cyst, which was connected to the esophagus via an obliterated fistula. There was no communication between this cyst and the trachea. Histological examination of the removed cyst revealed four layers of tissue, consistent with esophageal tissue: mucosa, submucosa, muscularis propria, and either serosa or adventitia. A six-month follow-up ultrasound confirmed no residual disease or recurrence. This case marks only the fourth such instance reported globally.
