The congenital duplication cyst: a rare differential diagnosis of retrosternal pain and dysphagia in a young patient

Oesophageal duplication cysts, a rare cause of neck lump treated by ultrasound guided drainage: case report and review of the literature

Oesophageal duplication cysts are a rare congenital anomaly of the foregut which usually present in infancy with respiratory symptoms, recurrent pneumonia and feeding difficulty. Other presenting symptoms depend on the location of the cyst and can include dysphagia, chest pain, arrhythmias and features of mediastinal compression. Treatment is usually surgical resection, recommended for complete resolution of symptoms, histological diagnosis and exclusion of malignancy. Here, we present a case of infected oesophageal duplication cyst which presents as a neck lump in a 43-year-old female with a background of Goltz syndrome, azygos fissure and congenital aortic stenosis. Surgical resection was decided against owing to the patient's high risk secondary to co-morbidities and instead ultrasound guided drainage was carried out successfully. The patient was symptom free and well at 1-year follow-up. Oesophageal duplication is an unusual presentation of a neck lump in an adult and whilst the usual treatment is surgical resection, we present here a case treated in an entirely different manner.

Esophageal Duplication Cyst in a Dog

A cranial cervical mass was surgically removed from a dog. On histologic examination, the mass was consistent with an esophageal duplication cyst, a condition rare in humans and not reported in the dog.

Mediastinal foregut duplication cyst presenting as a rare cause of breathing difficulties in an adult

Foregut duplication cysts are rare congenital anomalies of enteric origin. The diagnosis is usually made in infancy. We report the unusual case of a 71-year-old female presenting to the ENT department with shortness of breath and stridor due to an oesophageal reduplication cyst. The presentation, diagnosis and management of this potential pitfall for the unwary are outlined.

Intra-abdominal esophageal duplication cysts: a review

Esophageal duplication cysts (EDCs) are well described within the literature, normally occurring within the mediastinum. Intra-abdominal EDCs are rare and typically occur near the intra-abdominal esophagus. Herein, we describe two cases of intra-abdominal EDCs: a 60-year-old man who was incidentally found to have a retro-duodenal cystic mass and a 50-year-old woman with a cystic lesion near the body and tail of her pancreas causing left flank pain. Both patients underwent enucleation of their respective masses. Pathology revealed ciliated pseudostratified columnar epithelium with scattered mucus-secreting cells and two smooth muscle layers in the cyst wall of both patients, consistent with EDCs. Although intra-abdominal EDCs have been reported in the literature, our two cases and a review of the literature indicate that these lesions are not always adherent to or even near the intra-abdominal esophagus.
