title: [Anomalous systemic arterial supply to the lower lobe of the right lung: a rare finding].
abstract: Vascularization of a segment or lobe of the lung from a systemic artery is a rare anomaly. The lower left lobe is usually involved and clinical presentation typically includes hemoptysis, chest pain, exercise-related dyspnea or murmurs. Some patients are asymptomatic and discovery is fortuitous. Diagnosis depends on images, with angiography and, most recently, helicoid CT scan proving most useful. Treatment is nearly always surgical, with or without prior embolization of the anomalous vessel.We report the case of a 31-year-old man with anomalous systemic arterial supply to the lower right lobe discovered while we examined a pulmonary node that appeared benign. The location was unusual. We discuss diagnostic procedures and assess the relation between this condition and lung sequestration and hypogenetic lung syndrome.
