Mycotic aortic aneurysm diagnosed by In-111 leukocyte scintigraphy and computed tomography.

The diagnosis of mycotic aneurysm is often elusive, since the patient frequently has signs and symptoms of sepsis only. A patient with a clinically occult mycotic aneurysm was assessed by the combined use of indium-111 leukocyte scintigraphy and computed tomography. While neither study was diagnostic by itself, the combined information obtained from the two noninvasive modalities facilitated the correct diagnosis preoperatively.
