[Diagnosis and treatment of pediatric cervical bronchogenic cyst].

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.

Role of esophageal ultrasound with a bronchoscope (EUS-B) with fine needle aspiration in the diagnosis of mediastinal Bronchogenic cyst.

A 12-year-old adolescent boy presented with complaints of persisting dry cough and exertional dyspnea. A CT chest revealed a cystic lesion posterior to the trachea and a flexible bronchoscopy revealed extrinsic compression of the posterior trachea and partial obstruction of the left main bronchus. He underwent an Endoscopic Ultrasound with a Bronchoscope. A Hypoechoic cystic lesion was seen just in front of the esophagus. Fine needle aspiration yielded thick mucoid aspirate and cytology revealed ciliated columnar epithelium, confirming the diagnosis of a Bronchogenic cyst.

Segmental Dilatation of Ileum Involving Bronchogenic Cyst in a Newborn.

Objective: Congenital segmental intestinal dilatation (SID) and bronchogenic cyst in the abdomen are two uncommon and different pathologies. We report a bronchogenic cyst associated with segmental intestinal dilatation. Case: A 2-day-old 3300 g term infant developed bilious vomiting. A jejunoileal segment with a diameter of 10 cm was detected at surgery. Histologically, the wall musculature and enteric plexus of the segmentally enlarged small intestine stained normally for CD117 and negative for calretinin. A bronchogenic cyst of 3 cm in diameter was centered on the mesenteric border of the dilated intestine. Conclusion: SID has a normal staining pattern for CD117 (for interstitial cells of Cajal) and negative for calretinin. it would suggest that the innervation is defective, may be associated with a bronchogenic cyst in the newborn, causing obstruction, requiring surgery.

[A case of mediastinal bronchial cyst misdiagnosed as schwannoma: a case report].

A case of mediastinal bronchial cyst misdiagnosed as schwannoma is reported. The patient had no chest pain, dyspnea, cough, sputum and hemoptysis in the past. Chest enhanced CT showed mediastinal mass with clear boundary. The larger cross-section was about 3.9 cm × 3.4 cm, and there was no obvious enhancement. The primary diagnosis was considered as schwannoma, tracheal cyst or esophagus cyst. The mediastinal tumor was resected via cervical approach under general anesthesia. During the operation, it was found that the mass was located in the middle and upper mediastinum, with diameter of about 4 cm and a smooth surface, containing gelatinous cystic fluid and adhered to the esophagus and trachea. Postoperative pathological diagnosis was bronchogenic cyst. The patient recovered well after the operation, and has not recurred since follow-up.

Pitfalls in the surgical treatment of undiagnosed lung lesions and cystic pulmonary hydatidosis.

BACKGROUND: Hydatid cysts can mimic many lung pathologies radiologically, as well as some malignant or benign lung tumors may show hydatid cyst-like radiological features. The aim of our study is to present our clinical experience and recommendations by analyzing the cases that create diagnostic difficulties by presenting a common radiological pattern with a pulmonary hydatid cyst. METHODS: The patients who were operated on with a preliminary diagnosis of hydatid cyst but were diagnosed differently, and who were operated on with different prediagnoses and unexpectedly diagnosed with hydatid cyst were included in the study. The clinical and radiological features of the patients were documented, and the features of the cases that could cause difficulties in diagnosis and treatment for the surgeon were revealed. RESULTS: A total of 20 patients who were radiologically suggestive of hydatid cyst but were diagnosed differently or unexpectedly diagnosed as hydatid cyst were included in the study. Lung cancer, bronchogenic cyst, or bronchiectasis were detected in 13 patients who were radiologically suggestive of hydatid cyst. There were 7 patients who were diagnosed with hydatid cysts, although they did not have specific radiological findings. CONCLUSIONS: While hydatid cysts can mimic many lung pathologies, many benign or malign parenchymal lung pathologies may exhibit hydatid cyst-like radiological features. Therefore, in regions where a hydatid cyst is endemic, the surgeon should consider all possibilities while managing the cases.

Transesophageal endoscopic resection of mediastinal cysts (with video).

BACKGROUND AND AIMS: Primary mediastinal cysts are infrequent lesions derived from a variety of mediastinal organs or structures. Complete surgical resection is the treatment of choice even in asymptomatic patients to prevent severe adverse events (AEs) and to establish the diagnosis. Transesophageal endoscopic resection of benign mediastinal tumors has been proven feasible. The aim of this study was to evaluate the feasibility, safety, and efficacy of transesophageal endoscopic surgery for mediastinal cysts. METHODS: From January 2016 to May 2021, patients with mediastinal cysts who underwent transesophageal endoscopic resection were retrospectively included. Clinicopathologic characteristics, procedure-related parameters, AEs, and follow-up outcomes were analyzed. RESULTS: Ten patients with mediastinal cysts were included in this study. The mean cyst size was 3.3 ± 1.3 cm. Histopathology revealed 3 bronchogenic cysts (30.0%), 4 esophageal duplication cysts (40.0%), 2 gastroenteric cysts (20.0%), and 1 lymphatic cyst (10.0%). All procedures were performed uneventfully without conversion to traditional surgery. En-bloc resection was achieved in 6 patients (60.0%). Aggressive resection was avoided to prevent damage to the surrounding vital organs. Mean resection time and suture time were 58.0 ± 36.4 minutes and 5.4 ± 1.0 minutes, respectively. No major pneumothorax, bleeding, mucosal injury, or fistula occurred. One patient had a transient febrile episode (>38.5°C). Mean postoperative hospital stay was 2.7 ± .9 days. No residual or recurrent lesions were observed in any patient during a mean follow-up period of 29.8 ± 19.5 months. CONCLUSIONS: Transesophageal endoscopic surgery appears to be a feasible, safe, effective, and much less invasive approach for mediastinal cyst resection. Larger prospective studies are required to fully assess the efficacy and safety of this novel technique.

A Bronchogenic Cyst Masquerading as a Tongue Mass.

Bronchogenic cysts are foregut-derived developmental anomalies found along the developmental pathway of the foregut. The putative theory of pathogenesis is abnormal budding or branching of epithelial cells during the development of tracheobronchial tree. Over 99 % of cases occur in the mediastinum and lung while the head and neck area is affected in less than 1 % of cases with only rare cases reported in the oral cavity. This is a report of a case of a bronchogenic cyst arising in a 6-year-old male. The lesion presented as a painless swelling of the left underside of the tongue. Microscopically, the cyst was lined by pseudostratified columnar epithelium exhibiting many ciliated and mucous cells. A focus of cartilage and discontinuous bundles of smooth muscle were present adjacent to the lining. Where there was cyst rupture, there was granulation tissue associated with many foamy macrophages and acute and chronic inflammation. Four other cases, three in the tongue and one in the lower lip vestibule with cutaneous extension, all in the midline, have been reported in a 1 day-old male, 4 year-old male, 6 year-old female and 3 year-old male. There was no recurrence after excision and this is in keeping with the behavior in previous reports. Other developmental cysts including foregut cysts may be focally lined with respiratory epithelium but the presence of cartilage is the sine qua non for the diagnosis of a bronchogenic cyst.

Bronchogenic cyst in an unusual location.

Bronchogenic cysts are congenital anomalies of the respiratory tract, which can affect children or adults. In adults, these cysts may be asymptomatic or present with symptoms, most often pain or cough. Intrapericardial cysts are rare and represent 27% of bronchogenic cysts. We present the case of a symptomatic adult with an intrapericardial bronchogenic cyst, who underwent surgical resection of the cyst, which successfully relieved his symptoms.

Giant presternal subcutaneous bronchogenic cyst: a rare but possible occurrence.

Bronchogenic cysts are generally detected in the mediastinum, along the tracheobronchial tree, or in the lung parenchyma. Subcutaneous presternal bronchogenic cysts have been rarely described, and they are usually of small size (<3 cm) and reported in children. We report a case of giant presternal subcutaneous bronchogenic cyst in a 20-year-old man. Presternal subcutaneous bronchogenic cysts, despite their rarity, should be considered in the differential diagnosis of all subcutaneous cystic masses, independent of their size and the patient's age.

Retroperitoneal bronchogenic cyst resembling an adrenal tumor: two case reports and literature review.

Bronchogenic cysts are primitive, foregut-derived developmental anomalies with bronchial-type, pseudostratified cylindrical epithelium. They are usually discovered in the thorax. The occurrence of such cysts in the retroperitoneum is extremely rare. Imaging techniques are generally effective in the detection of retroperitoneal bronchogenic cyst. Here, we report two cases (a 27-year-old man and a 33-year-old man) who had no clinical symptoms and were found by chance to have masses in the adrenal gland area during routine physical examination. We found that they had some similar computed tomography imaging features, including complete adrenal structure, cystic fusiform mass in adrenal region, and inclusion of calcifications in the lesions. However, accurate preoperative diagnosis remains difficult and only histology can provide a definitive diagnosis. Surgery remains the treatment of choice.

Resection of a Giant Bronchogenic Cyst in the Left Atrium.

A bronchogenic cyst in the left atrium is rare. We report the case of a 17-year-old male patient who was admitted to the emergency department because of severe chest pain and dyspnea. He was diagnosed using echocardiography and computed tomography, which revealed a huge cardiac tumour in the dome of the left atrium. He was surgically treated with tumour enucleation. The resultant atrial dome defect was reconstructed with a bovine pericardial patch. Pathologic investigation revealed that the tumour was a bronchogenic benign cyst.

Bronchogenic Cyst: Skull Base Lesions with Extracranial Extension.

BACKGROUND: Intracranial bronchogenic cysts (BCs) are extremely rare. To our knowledge, this is the first report of a BC in which lesions involve the middle and posterior cranial fossa, as well as the infratemporal fossa. CASE DESCRIPTION: We present the case of a 38-year-old woman who suffered from a cranial nerve dysfunction for 2 years. Magnetic resonance imaging showed that there were skull base communication lesions across the middle and posterior fossa. The patient was operated on through an infratemporal fossa approach. The final diagnosis was BC after histopathologic examination and immunohistochemical verification. The patient's neurologic dysfunction was partially ameliorated at the half-year follow-up. CONCLUSIONS: Intracranial BCs are rare. However, they should be considered in the differential diagnosis for cystic lesions with edge enhancement or extracranial extension.

Bronchogenic cyst of the interatrial septum.

Although bronchogenic cysts are the most common primary mediastinal cysts, intracardiac bronchogenic cysts are extremely rare. We report a case of a bronchogenic cyst of the interatrial septum in a 42-year-old woman who presented with recent onset of dyspnea on exertion. Cardiac investigations including transthoracic echocardiography and computed tomography revealed a cystic homogeneous mass in the interatrial septum. The patient underwent surgical resection, and the resultant atrial septal defect was repaired using an autologous pericardial patch. Histopathological examination of the resected specimen revealed findings consistent with a benign bronchogenic cyst. Although bronchogenic cysts are extremely rare, they should be considered in the differential diagnoses of intracardiac tumors. Complete resection of bronchogenic cysts is recommended primarily for diagnostic and potentially therapeutic purposes.

A rare case of pelvic bronchogenic cyst treated by laparoscopic surgery.

A 31-year-old man with pain in his thigh was diagnosed with a benign presacral cystic mass. We performed laparoscopic subtotal resection of the cyst utilizing mobilization of a total mesorectal excision procedure used in low anterior resection for rectal cancer. Histopathological findings showed that the cystic lumen of the specimen was lined with pseudostratified columnar ciliated epithelium and had glandular structures and smooth muscle in its wall, leading to a diagnosis of bronchogenic cyst. The postoperative course was uneventful, and as of 6 months after surgery, the patient was doing well with no evidence of recurrence.
