Coronary artery involvement in idiopathic retroperitoneal fibrosis: computed tomographic findings.

We describe 2 patients with perivascular low-attenuation soft tissue and inflammatory changes surrounding the coronary arteries in the clinical setting of idiopathic retroperitoneal fibrosis. Neither patient had inducible ischemia on cardiac stress testing. The coronary arteries present an additional site of interest as connections between sclerosing diseases-including retroperitoneal fibrosis, fibrosing mediastinitis, autoimmune pancreatitis, sclerosing cholangitis, and other entities-continue to emerge.
