Bronchogenic cyst is a rare clinical entity that occurs due to abnormal development of the foregut; the majority of bronchogenic cysts have been described in the mediastinum and they are rarely found in an extrathoracic location.
We describe the case of an intra-abdominal bronchogenic cyst of the mesentery, incidentally discovered during an emergency laparotomy for a perforated gastric ulcer in a 33-year-old Caucasian man.
Bronchogenic cyst should be considered in the differential diagnosis of subdiaphragmatic masses, even in an intraperitoneal location.
The laryngotracheal groove appears at the end of the third week of gestation in the embryonic foregut ; the dorsal portion of the foregut elongates to form the esophagus, and the ventral portion ultimately differentiates into the respiratory tract, with ciliated epithelium lining both the fetal esophagus and trachea [1–3]. Bronchogenic cyst and esophageal duplications are clinical malformations due to abnormal development of the foregut.
Bronchogenic cysts form from accessory ventral buds arising from the foregut distal to the future lung at about the fifth week of intra-uterine life; the majority of bronchogenic cysts have been described in the mediastinum (90%, most commonly in the posterior aspect of the superior mediastinum [4–8]) and they are rarely found in an extrathoracic location; a small number of them have been reported in abdominal location, with prevalence in the retroperitoneal space [9–12].
We report a bronchogenic cyst incidentally discovered as a small intra-peritoneal mass in our patient, who was admitted to our surgical unit for acute abdominal pain due to gastric ulcer perforation.
Our patient, a 33-year-old Caucasian man, was referred to our institution for acute abdominal pain; the symptoms had begun two days earlier as a mild epigastric pain that localized the following day in the right iliac fossa. He had no instances of nausea or vomiting at admission, a body temperature of 37.2°C, a white blood cell count of 20.30 cells/mm3 (polymorphonuclear leukocytes 84.6%) and sluggish peristalsis. He had a history of misuse of a non-steroidal anti-inflammatory drug (NSAID) used to manage his back pain without any medical prescription.
Our patient was discharged on the twelfth post-operative day.
Bronchogenic cysts originate from an accessory lung bud of the primitive foregut after the third week of embryonic life. Most commonly they migrate caudally with the esophagus and are eventually found in the posterior mediastinum near the carina, attached to the tracheobronchial tree or to the esophagus. Rarely the cyst may separate completely from its origin and may be found in unusual sites, such as pericardium, skin [13, 14] or in intra-spinal locations. Most bronchogenic cysts are small and are usually discovered incidentally because patients are asymptomatic, though sometimes there can be epigastric or left upper quadrant abdominal pain. Malignant transformation is rare .
A subdiaphragmatic location is extremely rare, with only about 20 cases reported in the literature [13–19]. This is due to the migration of the cyst prior to the fusion of the pleuroperitoneal membrane. Our patient's cyst was unilocular and arose from the ileal mesenterium, and was filled with mucin.
Bronchogenic cyst should be considered in the differential diagnosis of subdiaphragmatic masses, even in intra-peritoneal location.
Written informed consent was obtained from the patient for publication of this case report and any accompanying images. A copy of the written consent is available for review by the Editor-in-Chief of this journal.
