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.
