Abstract
Abdominal aortic aneurysm (AAA) may be incidentally detected in three-phased bone scintigraphy. AAA should be diagnosed prior to the development of symptoms to perform elective repair surgery. We present a rare case who presented with back pain and underwent a 3-phase bone scan with Tc-99m methylene diphosphonate, which revealed a giant AAA on blood-flow and blood-pool phases in addition to bone metastases. F-18-fluorodeoxyglucose positron emission tomography/computed tomography (CT) identified hypermetabolic liver, lung, and bone lesions, and CT component of the study confirmed the diagnosis of AAA with a maximum diameter of 92 mm. The initial two phases of a 3-phase bone scintigraphy are decisive to identify vascular pathologies that may be life-threatening, if left untreated.
Highlights
Abdominal aortic aneurysm (AAA) may be incidentally detected in three-phased bone scintigraphy
AAA is more likely found among men, and only 1-2% of male patients are older than 50 years (4,5)
AAA should be identified accurately prior to development of symptoms and elective repair is the mainstay of treatment to prevent rupture and sudden death, especially for patients who have AAA with a maximum diameter >5.5 cm, a saccular aneurysm, or an abdominal or back pain that can be attributable to AAA
