Preoperative chest X-ray and computed tomography images. a Chest X-ray image showing abnormal consolidation in the left lower lung field (yellow arrow). b Enhanced computed tomography revealed the presence of an aberrant artery with a maximum diameter of 33 mm (yellow arrowheads) with a thrombosed lumen (asterisk). c Three-dimensional computed tomography from posterior view revealed an aneurysmal aberrant artery (yellow arrowheads) arising from the celiac artery. We resected the aberrant artery with pulmonary ligament (black dotted line). After surgery, we performed coil embolization on the residual aberrant artery (asterisk). d Three-dimensional computed tomography from anterior view showed that the aneurysmal aberrant artery (yellow arrowheads) arose from the celiac artery and was flowing into the left lower lobe along the pulmonary ligament forming an aneurysm. It was divided along with the pulmonary ligament (black dotted line)
