Pulmonary sequestration is a congenital anomaly in which a systemic circulation artery supplies a lung parenchyma. This malformation is classified into three types by Pryce, based on the pathological pattern. Pryce type I pulmonary sequestration is rare (1). Three-dimensional (3D) multi-detector row computed to-mography (CT) has changed how we image thoracic anatomy and disease in evaluations of systemic and pulmonary vasculature and the tracheobronchial tree (2). Here we present a case of Pryce type I pulmonary sequestration accompanied with an aneurismal aberrant artery diagnosed by CT. A 50-year-old male suffered from a brain aneurysm (left VA-PICA, diameter 4-5 mm) and hypertension (175/114 mmHg) and had been treated with an anti-hypertensive. Seven months later, he complained of left flank pain.
