This article reviews the spectrum of rare benign and malignant appendiceal lesions by correlating computed tomography findings with histologic features. The authors emphasize that these conditions can mimic acute appendicitis clinically, necessitating a thorough understanding of their distinct imaging characteristics for accurate diagnosis. The paper illustrates various pathologic changes associated with these diseases to aid radiologists in recognizing atypical presentations beyond common inflammation. Relevance to endometriosis: listed as one indication for GnRH antagonists, though the paper's main focus is uterine fibroids.

Abstract

Although acute appendicitis is the most common disease of the appendix, the appendix can be involved by a wide range of diseases. Diseases other than acute appendicitis may produce signs and symptoms indistinguishable from those of acute appendicitis. Computed tomography (CT) can provide important information for diagnosis and evaluation of appendiceal diseases. The various CT and histologic features of appendiceal benign and neoplastic diseases are discussed, illustrated, and correlated in this article. Radiologists need to understand the full spectrum of appendiceal abnormalities, their underlying pathologic changes, and associated CT imaging findings.
