A unique case of an infarcted carcinoid of the appendix is presented in which the computed tomography (CT) and clinical findings mimicked an appendiceal abscess. Though unusual, this possibility and appearance should be familiar to the radiologist particularly if percutaneous drainage is considered.

D002276	Carcinoid Tumor	A usually small, slow-growing neoplasm composed of islands of rounded, oxyphilic, or spindle-shaped cells of medium size, with moderately small vesicular nuclei, and covered by intact mucosa with a yellow cut surface. The tumor can occur anywhere in the gastrointestinal tract (and in the lungs and other sites); approximately 90% arise in the appendix. It is now established that these tumors are of neuroendocrine origin and derive from a primitive stem cell.
