Incidental finding of an aberrant left pulmonary artery, an aberrant right subclavian artery, and a tracheal bronchus in an adult woman with a meningioma and a history of medulloblastoma.

The aberrant left pulmonary artery and the aberrant right subclavian artery are rare congenital vascular anomalies, and the tracheal bronchus is a rare congenital respiratory anomaly. A 33-year-old female patient, with a history of desmoplastic medulloblastoma, was surgically treated at our hospital for a meningioma. On the second postoperative day, the patient complained of shortness of breath and chest pain. Contrast-enhanced multislice computed tomography was negative for pulmonary embolism, but incidentally revealed all three congenital anomalies. In our report, we detail this exceedingly rare case.
