CT morphology of anomalous systemic arterial supply to normal lung in dogs

“…In our cases, there was no evidence of chronic pulmonary parenchymal inflammation, abnormal pulmonary venous return, or abnormal bronchial connections. Furthermore, the aberrant systemic artery solely supplied the normal caudomedial portion of the right or left lobes without normal pulmonary arterial supply to the involved area; these findings are consistent with the diagnosis of ASANL 8,13 …”

A Case of a Systemic-to-Pulmonary Artery Fistula and Its Endovascular Treatment

“…Aberrant supply from the descending aorta in the left lower lobe with normal bronchial tree are the common findings of ASANL. With this abnormality, there may be a normal pulmonary supply to the involved parenchyma or may be absent (4). In contrast, in our case, the lingula was the involved segment, and the systemic supply was not from the descending aorta.…”

“…It is presumed that pleural adhesions subsequent to chronic inflammation may trigger the development of transpleural S-PA anastomoses by activating neovascularization from the systemic circulation (1). At the end of this process, chronically inflamed lung tissue turns into a mass of scar tissue, so-called pseudosequestration, that demonstrates peripheral contrast enhancement, with a tangle of anastomotic vessels supplied by a hypertrophied systemic artery, e.g., intercostal arteries, IMAs, inferior phrenic arteries (1,4). In our case, the absence of such finding excluded the diagnosis of pseudosequestration.…”

Dilated cardiomyopathy as a rare presentation of the pulmonary sequestration: A case report with aberrant vessel from aorta to left lower pulmonary lobe

“…Bronchopulmonary sequestration is rare congenital anomaly. The undiagnosed aberrant systemic arterial supply to lung could lead to development of non-ischemic cardiomyopathy and congestive heart failure in adults [1]. Hereby, we report a case of reversible cardiomyopathy after coil embolization of aberrant vessel to lung.…”
