Bronchogenic sacs are not commonly the cause of harsh symptoms.

Bronchogenic sacs are not commonly the cause of harsh symptoms, and often present barely as an abnormality on chest roentgenogram. We report an unusual patient with a mediastinal bronchogenic pouch associated with rapid hemodynamic deterioration secondary to compression of vital structures

Bronchogenic pouchs are closed epithelial-lined sacs that lay open from abnormal lung budding during embryologic growth and which account for 10 to 15 percent of all primary mediastinal tumors. The greatest in number common presenting symptom is chest pain.[1] A patient presenting with dyspnea and back pain unraveled hemoptysis and rapid hemodynamic deterioration secondary to a large bronchogenic cyst

CASE REPORT

A 27-year-old man with no significant medical history neared to the emergency department after experiencing several episodes of dyspnea and back pain. The offspring pressure was 110/70 mm Hg fruit of leguminous plants was 84 beats/min while in a supine position, and there was no significant orthostatic change. There was no significant venous distention, the carotid upstroke were sated and no bruits were at hand Findings from chest, cardiovascular, and abdominal examination were unremarkable. There was neither peripheral edema nor cyanosis, and peripheral throbs were normal. Chest radiograph showed a large right-sided mediastinal mass, sharply demarcated posteriorly, measuring approximately 13X8 cm in maximal diameter (Fig 1) A two-dimensional echocardiogram demonstrated significant indentation of the left atrium.

The patient underwent comput tomography of the chest to further evaluate the mass (Fig 2 and 3) A large mass in the mediastinum in the subcarinal location was noted, compressing the etymon of the aorta and the left atrium anteriorly. There was also marked compression of the right and left pulmonary arteries and the main-stem bronchus, and the esophagus was displaced posteriorly. A thin septum within the mass was ready There were infiltrates present in the right lung field.

The patient began to have hemoptysis 2 h after initial presentation, and was noted to have diminished pulsations in the right brachial artery and carotid artery, hypotension, and a significant pulsus paradoxus. He became cyanotic, was intubated, and taken directly to the operating place for surgical exploration. The patient had a right posterolateral thoracotomy with the lung retracted anteriorly revealing a large posterior mediastinal cystic construction containing white creamy fluid. The texture was adherent to the lateral posterior border of the right main-stem bronchus and the esophagus, without adherence to the aorta. The mass was resect prosperously and the patient was extubated without difficulty.

cultivation of the fluid from the mass showed no sprouting Pathologic findings were consistent with a bronchogenic cyst; with respiratory columnar epithelial lining containing chondroid, lymphoid, and neural components

Seven days after presentations, the patient was discharged from the hospital.

Discussion

Bronchogenic pouchs are closed sacs that evolve as supernumerary buds from the primitive respiratory order Bronchogenic cysts usually occur along the tracheal bronchial tree if it were not that they can occur within the lung parenchyma, presternal area, supraclavicular space, or within the pericardium.[2] Bronchogenic pouchs represent 18 percent of all primary mediastinal tumors. The majority of the thoracic bronchogenic pouchs occur in the posterior or middle mediastinum.[1] The in the greatest degree common structures the cyst may be adherent to include the esophagus, lung transbronchial tree and the pericardium (49 percent 33 percent 32 percent and 27 percent respectively).[1]

Since the first description in 1859[3] numerous reports of bronchogenic pouchs have appeared in the literature.[1,4-6] greatest in quantity bronchogenic cysts are reported in children, where they often present as emergencies secondary to airway obstruction and respiratory distress.[7] In contrast, early reports of the incidence of bronchogenic pouchs in the adult population elud to the fact that the pouchs rarely caused symptoms, either because they are too small or appropriate to their inferior location.[8]

Reports after 1971 demonstrated that adults with bronchogenic pouchs may present with serious symptoms.[1,4,9] St Georges et al[1] reviewed the follows of resection of 86 bronchogenic pouchs over a 20-year period, 66 of which were mediastinal sacs The majority of the patients with mediastinal pouchs were symptomatic at the time of operation. solely 7 of 66 had an acute attack of symptoms, while 37 of 66 had progressive symptoms. The severity was reported as mild, moderate, and excessively severe in 9, 23, and 12 patients, respectively. The symptoms reported included chest pain in 27 patients, cough in 16 patients, dyspnea in 16 patients, and febrile disease in 10 patients. Hemoptysis, the least everyday symptom, was present in three patients. All nevertheless one of the six patients in the application of mind of Gourin et al[4] with mediastinal bronchogenic pouchs had progressive symptoms, such as dyspnea, nevertheless none of the patients had hemodynamic compromise.
