Mycobacterium avium lung disease combined with a bronchogenic cyst in an immunocompetent young adult

We report a very rare case of a bronchogenic cyst combined with nontuberculous mycobacterial pulmonary disease in an immunocompetent patient. A 21-year-old male was referred to our institution because of a cough, fever, and worsening of abnormalities on his chest radiograph, despite anti-tuberculosis treatment. Computed tomography of the chest showed a large multi-cystic mass over the right-upper lobe. Pathological examination of the excised lobe showed a bronchogenic cyst combined with a destructive cavitary lesion with granulomatous inflammation. Microbiological culture of sputum and lung tissue yielded Mycobacterium avium. The patient was administered anti-mycobacterial treatment that included clarithromycin.

Unusual Bronchopulmonary Foregut Malformation Associated with Pericardial Defect: Bronchogenic Cyst Communicating with Tubular Esophageal Duplication

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.

Bronchogenic cyst -- cause of refractory wheezing in infancy.

A 1 1/2-year-old male child with past history of recurrent wheezing presented with a severe and refractory episode following a peanut aspiration. A bronchoscopy was done and the peanut removed. However, as the wheezing persisted a detailed evaluation was done which revealed a bronchogenic cyst. Surgical excision of the cyst was done and the child improved symptomatically. Congenital lesions need to be ruled out in infants and children with persistent and refractory wheezing.

Quiste broncogénico fetal: diagnóstico antenatal y revisión de la literatura / Fetal bronchogenic cyst: prenatal diagnosis and review of literature

Las patologías torácicas son poco frecuentes. Dentro de éstas se encuentran los quistes broncopulmonares, que por lo general son de carácter benigno. Se presentan dos casos de diagnóstico antenatal, de evolución benigna y resolución espontánea.

Doença cística traqueobrônquica / Tracheobronchial cystic disease

Cistos aéreos que emergem anormalmente da traquéia e/ou brônquios de maior calibre são doença extremamente rara. Na literatura encontram-se poucas descrições de casos isolados de cistos paratraqueais associados a pneumopatias crônicas. Relatamos dois casos dessa entidade clínica, rara, em membros de uma mesma família: o pai das pacientes faleceu dessa doença com 43 anos de idade e as duas filhas encontram-se em tratamento. O quadro clínico é semelhante ao da supuração pulmonar crônica. O diagnóstico foi firmado através de broncovideoscopia e tomografia computadorizada de tórax com reconstrução em 3D e broncoscopia virtual. As pacientes estão sob observação e tratamento clínico paliativo.

Bronchogenic cyst presenting as dysphagia.

We report an adult patient who masqueraded as a case of gastroesophageal reflux disease for over 6 years. On close questioning he was found to have severe constricting pain in the retrosternal region and non progressive dysphagia for 6 years. Cineradiography of the oesophagus and CT scan chest revealed a large bronchogenic cyst compressing the oesophagus and the trachea. Excision of the cyst relieved the symptoms.
