Herein, we reported the case of a 32-year-old male patient presented with intermittent attacks of mild right chest pain and dyspnea for 2 years. On contrast-enhanced computed tomography (CT) of the chest, a non-enhancing subcarinal cystic lesion about 6×6. 5 cm was detected in the posterior mediastinum, consistent with the features of bronchogenic cyst. The lesion showed small calcific focus changing its position posteriorly when patient changes his position from supine to prone. The flecks of calcium within the fluid in a cystic lesion constitute the origin of the future cyst wall calcifications and may reflect the long-standing nature of the lesion. Surgical excision is preferred to avoid the expected complications, including fistula formation, ulceration, and infection.

Introduction: Bronchogenic cysts are rare congenital lesions which originate from ventral foregut and most commonly originated in the central mediastinum. They rarely have symptoms and at the time of diagnosis they usually are large, infectious or complicated. In this study a case report of bronchogenic cyst is reported.Case: The patient to be presented is a 47 years old man with sudden onset of chest pain, severe dyspnea, tachypnea and decreasing right lung sounds. Symptoms of pneumotorax were observed in lung radiography. The patient was treated by inserting chest-tube, but there was no response to the treatment. Urgent thoracotomy was performed. A large single bronchogenic cyst was detected in the right lung parenchyma attached to intermediate bronchus. Complete resection was performed. According to the pathology report, pneumothorax was developed secondary to rupture of the bronchogenic cyst.Conclusion: Lung parenchyma is not a common area for developing bronchogenic cyst but it has special importance because of its severe complications. Since exact diagnosis is not always possible before surgery, it is necessary to perform resection in all suspicious cases.

Difficult to treat asthma is an asthma syndrome that brings in our mind other differentials. Mediastinal masses are not common findings, but are important variables.Bronchogenic cyst is a congenital anomaly of the foregut that is typically found in the mediastinum and diagnosed accidentally. We present a 4-year-old girl with allergic asthma that began at 8-months of age and finally a bronchogenic cyst was detected in this patient. The patient had history of asthma since she was eight months old. She had a history of several asthma attacks which had partly responded to asthma management.During the last episodes of asthma attacks, she was hospitalized in Pediatric Intensive Care Unit. Imaging studies showed a 4x3 cm mass in the posterior part of the thoracic cavity that had led to tracheal narrowing was found for which the patient underwent thoracotomy and in surgical exploration a cyst that had compressed the thoracic trachea. Pathological examination of the cyst revealed a bronchogenic cyst. Bronchogenic cyst is an uncommon developmental abnormality but in a patient with obstructive pattern of airways it should be considered in differential diagnosis of asthma, especially if the asthma management is not successful.

We describe a rare case of LA mass in a 46-year-old man presenting to our service for ‎the evaluation of exertional dyspnea.‎ Echocardiography revealed a unilocular encapsulated large mass that was completely ‎embedded in the LA wall. Surgery was done and histological findings confirmed the ‎diagnosis of a bronchogenic cyst (Iranian Heart Journal 2002, 2003; 3(4) & 4(1): 74-‎‎76).‎

Background: Bronchogenic cysts (BCs) are congenital abnormalities of the primitive foregut, which are commonly found in the lung and mediastinum; however, they may rarely occur in the retroperitoneal region. Case report: We present a case of 20-day-old male newborn with a prenatal diagnosis of an abdominal mass who was referred and admitted to our hospital for further evaluation. Abdominal ultrasound and computed tomography scan demonstrated a retroperitoneal ill-defined solid mass locating on the upper ridge of the left kidney in close contact with the posterior wall of the stomach and pressure effects on the spleen hilum. Concerning presumptive diagnosis of neuroblastoma, less likely Wilms tumor, and subdiaphragmatic sequestration, surgery was carried out, and the mass removed completely. Pathological examination revealed a multiloculated cystic-solid mass with cystic spaces which was lined by respiratory epithelium, and the underlying fibrotic stroma contained islands of mature cartilage consistent with the diagnosis of bronchogenic cyst. Conclusion: Although BCs rarely occur, they should be considered in the differential diagnosis of a retroperitoneal mass in the neonates.

Background: Bronchogenic cysts commonly occur isolated in the bronchial tree, typically in the mediastinum. However, subcutaneous and cutaneous forms can rarely be found. Herein, we present a case of a 3-year-old girl with this lesion. Case Report: A 3-year-old girl presented to the clinic with an ulcerated plaque on her anterior chest wall. She mentioned a history of a skin-colored nodule on the same location that had been present since her birth, and was excised one year ahead with the diagnosis of epidermoid cyst. On examination, an ulcerative plaque was evident on the left midclavicular area with no tenderness, discharge, erythema, or regional lymphadenopathy. Incisional biopsy was performed. Histopathological study revealed non-dysplastic, squamous, pseudo-stratified, ciliated respiratory epithelium with diffuse inflammatory lymphomononuclear infiltration in the lower stroma, confirming the diagnosis of cutaneous bronchogenic cysts. The patient was referred for surgical resection of the lesion, but refused to continue the treatment. Conclusion: Although lesions associated with skin appendages are more common in the diagnosis of subcutaneous masses, less frequent diagnoses should also be in mind for lesions with special localization or recurrent and unusual course, and histopathological examination of tissue specimens should be performed.

Bronchogenic cyst is a result of abnormal development of the ventral foregut presents as a discrete mass. Most commonly, it is appeared in the middle mediastinum and rarely is seen in adults. We report a 35-year-old woman who was asymptomatic and incidentally was found with a mass in chest radiograph.

Introduction: Bronchogenic cysts are congenital cystic lesions that arise due to abnormalities during the embryonic development of the tracheobronchial tree. When located in close proximity to the trachea, they may lead to significant respiratory symptoms. Case Presentation: A 21-year-old female patient presented with persistent cough and intermittent dyspnea. Thoracic imaging revealed a cystic lesion measuring 3.8 × 5.8 × 4.4 cm located in the right paratracheal region. During uniportal video-assisted thoracoscopic surgery (u-VATS), a tracheal rupture occurred while dissecting the lesion. The tracheal injury was successfully repaired with primary suturing without conversion to open surgery, and the cyst was completely excised. Histopathological examination confirmed the diagnosis of a bronchogenic cyst. The patient was discharged uneventfully on the third postoperative day. Conclusions: The u-VATS is a safe and effective approach for the surgical management of bronchogenic cysts, offering advantages not only in diagnosis and treatment but also in the management of intraoperative complications. This case highlights the feasibility and novelty of managing intraoperative tracheal injury using the u-VATS approach, which offers a less invasive yet effective alternative in thoracic surgical emergencies.

A 42‑ year‑ old female with gradual‑ onset dyspnea on exertion and a systolic murmur is presented, in whom electrocardiogram showed left axis deviation with an Rsr’ pattern in lead V1. Chest X‑ ray had a pulmonary vascular shunt and echocardiography marked a large ostium primum atrial septal defect together with a cleft in the mitral valve, leading to a diagnosis of the partial atrioventricular septal defect. Furthermore, magnetic resonance imaging depicted an incidental cyst on the roof of the left atrium. The operation was performed, and the cyst was excised. It measured 15 mm in diameter, had a fibrotic wall and contained homogeneous gelatinous material. Histopathology showed a small simple cyst with a fibrotic wall, lined by cuboidal to respiratory‑ type columnar cells. No evidence of malignancy was noted. The patient had an uneventful postoperative course and was discharged in good clinical condition.
