Abstract
Inferior gluteal artery aneurysms are rare, and most reported cases involve posttraumatic symptomatic pseudoaneurysms that present with varied symptoms. We report a case of an inferior gluteal artery aneurysm without any history of trauma or symptoms, but was confirmed based on diagnostic imaging findings as a true aneurysm. A 26-mm aneurysm between the left gluteal muscles was detected by chance by CT in a 60-year-old man 5 years prior; however, he was asymptomatic and therefore underwent observational follow-up. The patient underwent treatment because of the enlargement of the aneurysm to 39 mm, which was 1.5 times its prior diameter, on CT examination for hepatocellular carcinoma. Percutaneous transarterial coil embolization was performed as our less-invasive treatment of choice considering that the patient had cancer. Postoperative course was not eventful, and 3 months after treatment, no blood flow was detected on the aneurysm. To our knowledge, this is the first case in which the patient was followed up for a gluteal artery aneurysm before treatment initiation.
