Intrapulmonary bronchogenic cysts are rare congenital anomalies that often present diagnostic and management challenges due to nonspecific symptoms. We report a one-year-old female with progressive respiratory distress who was initially misdiagnosed with pneumothorax. Imaging revealed a large intrapulmonary cyst, and surgical excision confirmed the diagnosis. Early intervention ensured a favorable outcome, with no recurrence in one year. This case highlights the importance of considering bronchogenic cysts in pediatric respiratory distress and emphasizes the value of timely surgical management.
