Anomalous pulmonary venous drainage (APVD) is a rare congenital anomaly in which the pulmonary veins do not connect normally to the left atrium. Mixed-modality APVD is particularly rare and therefore represents a diagnostic and therapeutic challenge. In this article, we report a case of mixed-modality APVD in a 9-month-old female patient, who initially presented with progressive respiratory distress and was subsequently diagnosed with APVD a high-complexity healthcare center, by means of computed tomography angiography. The purpose of the publication is to document and share details that may help other medical professionals recognize and diagnose similar cases in the future.
