Bronchogenic cysts are rare congenital cysts caused by anomalism of foregut in the embryonic stage.They locate most frequently in the mediastinum and are rarely seen in stomach.Here we report a case of gastric bronchogenic cysts that was diagnosed and treated in Peking Union Medical College Hospital from April 2 to 9,2018.

Bronchogenic cysts are generally found in the mediastinum, particularly posterior to the carina, but they rarely occur in such unusual sites as the skin, subcutaneous tissue, pericardium, and even the retroperitoneum. A 30-year-old Korean man underwent surgery to remove a cystic adrenal mass incidentally discovered during routine physical checkup. At surgery, it proved to be a multilocular cyst located in the retroperitoneum adjacent to the left adrenal gland. Microscopically, the cyst was lined by respiratory epithelium over connective tissue with submucous glands, cartilage and smooth muscle, thereby histologically confirming bronchogenic cyst. This is the first reported case of retroperitoneal bronchogenic cyst in an adult without other congenital anomalies in Korea.

Objective:To investigate the clinical characteristics and surgical treatment outcomes of children with cervical bronchogenic cysts. Methods:A retrospective study of 6 pediatric patients with bronchogenic cysts in the neck region treated in our hospital during 2014 to 2020 was performed. All children underwent complete resection of cervical mass under general anesthesia. Results:There were 6 children, aged from 1 to 5 years, with a median of 2.25 years. There were 3 males and 3 females. The lesions were located on the left neck in 3 cases, the midline neck in 2 cases and the right neck in 1 case. The clinical manifestations were painless mass in 5 cases and recurrent neck infection in 1 case. The size of the mass ranged from 2.1 to 7.5 cm. There was no characteristic clinical or imaging features of bronchogenic cysts. Misdiagnosed as lymphangioma in 3 cases, thyroglossal cyst in 2 cases and piriform fistula in 1 case. The follow-up ranged from 1.50 to 7.75 years, with a median of 4.13 years. All 6 children had no recurrence or complications. Conclusion:Although rare, bronchogenic cysts should be considered in the differential diagnosis of cervical cystic masses in children. Surgery is the most effective way to treat cervical bronchogenic cyst, and histopathological examination is the gold standard for diagnosis.

We report the case of a 69-year-old woman who was diagnosed with intracardiac schwannoma without symptoms. Preoperative echocardiography and cardiac magnetic resonance imaging showed a mass attached to the interatrial septum. The initial diagnosis was a myxoma or a bronchogenic cyst. The tumor was successfully excised under cardiopulmonary bypass. However, the pathology of the excised tumor was consistent with schwannoma. We suggest that cardiovascular surgeons consider schwannoma to be a possible differential diagnosis for a mass close to the interatrial septum.

OBJECTIVETo analyze the clinical features of retroperitoneal bronchogenic cyst.

METHODSThe clinical data of 6 cases with retroperitoneal brochogenic cyst treated in Peking Union Medical College Hospital from April 1996 to October 2014 were retrospectively analyzed. The clinical manifestation, diagnosis, treatment and prognosis were analyzed.

RESULTSOf the patients, 1 was male and 5 were female aging from 31 to 50 years with a mean age of 38.3 years. Three cases were diagnosed from physical examination, 2 cases from upper abdominal pain and 1 case from left flank pain. The cysts located in the left adrenal region, between the liver and the pancreas, and anterior aspect of the tail of the pancreas were seen in 4 cases, 1 case and 1 case, respectively. The major diameter was from 5 cm to 13 cm, and the mean major diameter was 7 cm. Ultrasonography and CT scan could reveal cystic, cystic-solid or solid masses. Color doppler flow imaging showed no obvious blood flow, and contrast-enhanced CT scans showed no enhancement or no obvious enhancement. Six cases were all misdiagnosed preoperatively. They all underwent operations via retroperitoneal laparoscopic resection for 3 cases, laparotomy for 2 cases and open flank resection for 1 case respectively. The pathological diagnoses were all bronchogenic cysts. Three symptomatic patients became asymptomatic after operations. Five patients had been followed up. During the follow-up of 2 months to 15 years, no recurrence had been found with CT scan.

CONCLUSIONSRetroperitoneal bronchogenic cyst is rare and easily misdiagnosed. It should be considered in the differential diagnosis of a retroperitoneal mass. Most cysts are positioned in the left adrenal region and adjacent regions. Some cysts demonstrate soft tissue characteristics in image. After surgical removal, the patients have a good prognosis.

We present a case of an intraperitoneal bronchogenic cyst located at inferior surface of the liver, next to the gallbladder which clinically mimicked a gallbladder tumor. This is the first case reported in Korea, and we offer reviews of the related literatures. A 48-yr-old woman was admitted to our hospital because of intermittent abdominal pain in right upper quadrant. Computed tomography showed a large mass alongside the gallbladder. During laparotomy, the mass showed an ovoid cystic nature, which was attached to the normal gallbladder and liver bed. Cyst excision with cholecystectomy was performed, and histopathological examination revealed a bronchogenic cyst. Most bronchogenic cysts have a benign nature, but malignant changes have also been reported. Therefore, if a cystic tumor in the abdomen is suspected during preoperative diagnosis, a bronchogenic cyst should be considered in the differential diagnosis.

Intraspinal bronchogenic cysts are rare congenital cystic lesions. In all the reported cases, the cysts have been located in the cervical, upper thoracic or thoracolumbar segments. We report the case of an intraspinal bronchogenic cyst in the sacral location. We present the case of a 5-month-old female with a skin dimple in the midline over the sacral vertebra. Magnetic resonance image of the lumbar and sacral vertebra revealed a dermal sinus tract and an epidural cystic mass at the S2 level. The patient underwent the removal of the dermal sinus tract and the cyst. The cystic mass was shown to be connected to the subarachnoid space through a slender pedicle from the dura. The cyst was diagnosed to be a bronchogenic cyst based on the results of the histopathological examination. We conclude that intraspinal bronchogenic cysts may appear in the sacral location.

We report a case of unusual bronchopulmonary foregut malformation composed of a mediastinal bronchogenic cyst with sequestrated lung tissue and communicating tubular esophageal duplication associated with complete pericardial defect. A 18-yrold man, who had suffered from dry cough and mild dyspnea, was admitted because of an incidentally detected chest mass. A computed tomography scan demonstrated a cystic mass with an air fluid level connected with esophagus in the middle mediastinum. The surgically resected mass was a pleural invested accessory lobe of the lung (8.0x7.0x4.5 cm) connected with the esophageal wall by a tubular structure (3.0 cm in length and 2.0 cm in diameter). A complete left pericardial defect was also identified. Histologically, the cystic wall was composed of fibrovascular connective tissue with a smooth muscle layer, mixed seromucous glands and cartilage, and the inner surface of the cyst was lined by ciliated pseudostratified columnar epithelium. The inner surface of the tubular structure was lined by non-keratinizing or keratinizing squamous epithelium, and the wall contained submucosal mucous glands, muscularis mucosa, and duplicated muscularis propria. This case is important in understanding the embryological pathogenesis of the variable spectrum of the bronchopulmonary foregut malformation.

OBJECTIVETo investigate the clinical features and management of bronchogenic cyst in the adults.

METHODSWe retrospectively reviewed 50 patients admitted to our hospital with histopathologically proved bronchogenic cyst from January 1983 to December 2007. Of all the patients, 28 were male and 22 were female, with an average age of 36.9 (range, 18 to 64) years. The symptoms, location of the cysts, imaging evaluation, surgical treatment manner, and outcome of these patients were analyzed.

RESULTSSymptoms were present in 33 of the 50 patients, and cough was the most common symptom. Thirteen patients presented with complications: hemoptysis, infected cyst, dysphagia, paralysis, and hoarseness. The locations of the cysts included the mediastinum (28 cases), pulmonary parenchyma (12 cases), hilar area (3 cases), visceral pleura (1 case), and some rare locations including the intestinal mesentery (1 case), retroperitoneum (1 case), adrenal gland (1 case), neck (2 cases), and dura matter of the cervical vertebrae (1 case). Chest X-ray was performed in 36 patients and computed tomography (CT) was performed in 41 patients. The bronchogenic cyst in CT was characterized as a round, well circumscribed, unilocular mass, with density ranging from that of water to high density (0-50 Hu). As for treatment, complete resection of the bronchogenic cyst was performed in 47 (94%) patients, subtotal resection was performed in 3 (6%) patients. Open surgery was performed in 45 (90%) patients, and thoracoscopy (video-assisted thoracic surgery) was performed in 5 (10%) paitients. Of the 12 patients with intrapulmonary cyst, 11 patients underwent lobectomy and 1 patient underwent wedge resection. Postoperative sequelae occurred in 2 patients, 1 with persistent air leakage and 1 with hoarseness. All patients were proved with bronchogenic cyst pathologically. The average follow-up period was 6.5 years (range, 4 months to 10 years), and no late sequelae or recurrence of the cyst occurred.

CONCLUSIONSThe clinical and imaging presentations of bronchogenic cyst in adults are variable. Surgical resection is the best way for diagnosis and treatment. Both open surgery and thoracoscopy are appropriate for the selected candidates.
