RationaleMeandering pulmonary vein is a rare congenital pulmonary vascular anomaly. It presents unilateral single pulmonary vein that takes a circuitous route in the lung and drains normally into the left atrium. Most cases of meandering pulmonary vein have been reported to be right-sided. A few of them coincided with features of scimitar syndrome.Patient ConcernsA 71-year-old woman and a 20-year-old man presented with incidentally found abnormal findings on chest radiographs.DiagnosisThrough multi-detector chest computed tomography, the 71-year-old woman was diagnosed as left-sided meandering pulmonary vein without any other anomalies while the 20-year-old man was diagnosed as having right-sided meandering pulmonary vein with features of scimitar syndrome.InterventionsSpecific intervention was not performed for either patient.OutcomesThese patients were reassured and discharged. They are doing well without any respiratory symptoms.LessonsMeandering pulmonary veins can occur on the left side and coincide with features of scimitar syndrome. Multi-detector computed tomography with 3D reconstruction allows clear depiction of vascular connections and associated anomalies, obviating the need for invasive procedures.
