Intralobar pulmonary sequestration (IPS) typically affects lower lung lobes and receives its blood supply from systemic arteries. Here, we present a unique case of a 51-year-old woman presented with recurrent nonmassive hemoptysis. Contrast-enhanced computed tomography angiography (CTA) of the chest showed uniform consolidation in the inferior lingular segment of the left upper lobe. Maximal intensity projection (MIP) and three-dimensional volume rendering (3D-VR) showed the affected area's blood supply from unusual arterial branches originating from the left inferior phrenic artery arising from the left gastric artery, consistent with IPS. A multidisciplinary approach utilized endovascular intervention (coil embolization) before successful surgical resection. Detecting IPS in unusual sites, like the lingular region, poses a diagnostic challenge. Clinicians and radiologists may not initially consider this diagnosis when evaluating patients with respiratory symptoms or incidental imaging findings. A comprehensive grasp of their anatomy and vascular variations is vital for precise diagnosis and effective treatment planning.MedicineArticleSCOPUS10.1016/j.radcr.2023.11.0472-s2.0-8518042775419300433
