Meandering pulmonary vein: Very rare incidental finding

Abstract

Meandering pulmonary vein (MPV) is a rarely seen pulmonary vascular anomaly and confused with the scimitar syndrome which is more commonly seen. In this paper, we presented a case of left MPV which mimes arteriovenous malformation. A 30-year-old man was referred to our clinic for pulmonary nodule detected in routine evaluation before employment examination. Diagnosis of MPV was made by Pulmonary CT angiography. It showed abnormal drainage of upper lob pulmonary vein to the inferior pulmonary vein and form abnormal common pulmonary vein which shouldn't be exist. Because of any symptoms no further examination was recommended. According to our best knowledge to date only 17 cases reported in the literature. MPV diagnosis has been significantly changed by the means of advances in CT technology. Non-invasive diagnosis is possible with modern multisectional CT that clearly shows the anatomy of veins and enables the detailed MPV examination. Hereby, unnecessary radiological examination or surgery can be prevented of veins and enables the detailed MPV examination.
