Appendiceal neoplasms are rare and often only discovered incidentally during surgery performed for acute appendicitis. Computed tomography (CT) has been demonstrated to be a reliable technique for accurately establishing the preoperative diagnosis of appendiceal neoplasms that manifest as acute appendicitis through the presence of certain imaging findings. Other manifestations of appendiceal neoplasms include appendiceal mass, mucocoele, localised abscess formation, ileus, increasing abdominal girth from pseudomyxoma peritonei, and intussusception. This pictorial essay illustrates varied CT findings of neoplasms of the appendix, with emphasis on the more commonly encountered manifestations of these tumours.
阑尾肿瘤较为罕见,通常仅在因急性阑尾炎行手术时偶然发现。计算机断层扫描(CT)已被证实是一种可靠的技术,可通过某些影像学表现准确地确定表现为急性阑尾炎的阑尾肿瘤的术前诊断。阑尾肿瘤的其他表现包括阑尾肿块、黏液囊肿、局部脓肿形成、肠梗阻、假性黏液瘤引起的腹围增大和肠套叠。本文通过图像说明展示了阑尾肿瘤的各种 CT 表现,重点介绍了这些肿瘤更为常见的表现形式。
