Congenital Pulmonary Airway Malformation in an Adult Male: A Case Report with Literature Review

Congenital Pulmonary Airway Malformation in an Adult Male Presenting With Hemoptysis

Congenital pulmonary airway malformations (CPAMs) are rarely encountered in the adult population. Although they are typically diagnosed in the prenatal period, some may not cause symptoms and go unnoticed until adulthood. Patients with CPAM are at risk of developing pneumonia, hemorrhage, pneumothorax, and malignancy. There is a paucity of evidence regarding the management and prognostication of adults with CPAM. Patients often need to undergo surgical resection to prevent further episodes of infection, bleeding, or malignant transformation. Here, we present the case of an adult male with a CPAM who presented with frank hemoptysis. Computed tomography scan and bronchoscopy localized the lesion to the lingula. The patient underwent elective surgical resection of the lesion by video-assisted thoracoscopy and did not suffer any adverse outcomes. Surgical resection is generally recommended and appears to be a safe and effective approach to treating patients with symptomatic CPAMs. Inhaled tranexamic acid and bronchial artery embolization are valuable interventions in our armamentarium for managing hemoptysis but should not replace a definite surgical intervention due to the risk of recurrence.

Pulmonary intralobar sequestration associated with aspergillosis and aspiration

The pathogenesis of intralobar pulmonary sequestration is not completely understood, either representing a congenital or acquired process. The presence of fungal organisms and aspiration has both clinical and etiologic significance.

A Missed Late Presentation of a Congenital Pulmonary Airway Malformation as a Large Infected Bulla

A congenital pulmonary airway malformation (CPAM) is a rare cystic anomaly that may occur during development of the fetal airways. The vast majority of CPAMs are detected in neonates; as such, it is unusual for diagnosis to occur in adulthood. We report a 21-year-old male patient who presented to the emergency department of the Hospital Ampang, Kuala Lumpur, Malaysia, in 2015 with chest pain, breathlessness and tachypnoea. Based on an initial chest X-ray, the patient was misdiagnosed with pneumothorax and underwent urgent chest tube insertion; however, his condition deteriorated over the course of the next three days. Further imaging was suggestive of infected bullae or an undiagnosed CPAM. The patient therefore underwent video-assisted thoracoscopic surgery, during which a large infected bulla was resected. A diagnosis of an infected CPAM was confirmed by histopathological examination. Following the surgery, the patient recovered quickly and no bullae remnants were found at a one-month follow-up.

Congenital pulmonary airway malformation in the asymptomatic adult: A rare presentation

Congenital Pulmonary Airway Malformation (CPAM) is a rare developmental abnormality of the lower respiratory tract, primarily diagnosed in the neonatal period. The most concerning sequelae for patients with CPAM are recurrent respiratory infections and malignancy. Rarely discovered in asymptomatic adults, CPAM presents challenging questions for management. We describe such a case and discuss the risks and benefits of resection.

The Use of Fetal Bronchoscopy in the Diagnosis and Management of a Suspected Obstructive Lung Mass

Etiologies of fetal lung anomalies include congenital pulmonary airway malformation (CPAM), intra- or extralobar pulmonary sequestration, congenital high airway obstruction syndrome (CHAOS), bronchogenic cyst, and bronchial atresia. Fetal tracheobronchoscopy has been reported both as a diagnostic and therapeutic procedure in the setting of severe congenital lung lesions. In this case report, prenatal imaging of a fetus with a large chest mass was suspicious for an obstructive bronchial lesion. The absence of visible normal lung tissue on the right side and mass effect on the left side raised the concern for pulmonary hypoplasia. After antenatal betamethasone and a period observation, hydropic changes developed. Fetal tracheobronchoscopy was then performed in an effort to identify and decompress the suspected obstructive bronchial lesion. Other than release of bronchial debris, no anatomical abnormalities were visualized. However, the right lung lesion and mediastinal shift both decreased after the fetal bronchoscopy. The newborn underwent postnatal resection of a CPAM Type II and is doing well. We hypothesize that fetal tracheobronchoscopy provided the following potential diagnostic and therapeutic benefits: (1) exclusion of an obstructive bronchial lesion; (2) disimpaction of bronchial debris from the saline lavage that we posit may have contributed to the rapid reduction in CPAM size.
