Background:
Intercostal artery aneurysms are rare vascular abnormalities that are typically diagnosed following rupture in patients with predisposing conditions. Our report is the first to document a patient with unruptured intercostal artery aneurysms in the absence of any associated disease.
Case Presentation:
A 70-year-old male with prostatic adenocarcinoma was incidentally discovered to have multiple unruptured aneurysms of his intercostal arteries. Three of the aneurysms were embolized utilizing microcoils and glue. At six-month follow-up the patient remained asymptomatic.
Conclusion:
We demonstrate successful endovascular management of a unique case of multiple idiopathic unruptured intercostal artery aneurysms. Appropriate diagnosis and prompt treatment of these rare vascular lesions is essential in preventing the potentially catastrophic consequences of rupture.
