Appendicitis and diverticulitis of the colon are the two main causes of febrile acute abdomen in adults. Diagnosis from imaging (ultrasound and CT) is usually easy. However, an imaging procedure which is not suitable for the clinical situation and an examination performed with the wrong protocol are sources of error and must be avoided. Anatomical variants, inflammatory cancers, complicated forms (perforation, secondary occlusion of the small intestine, peripheral abscesses, fistulae, pylephlebitis, liver abscesses) and associated signs related to a peritoneal inflammatory reaction (reflex ileus, reactive ileitis or salpingitis) can also lead to a wrong diagnosis.
阑尾炎和结肠憩室炎是成人发热性急腹症的两个主要原因。影像学（超声和 CT）诊断通常较为容易。然而，不适合临床情况的影像学检查程序和使用错误方案进行的检查都是错误的来源，必须加以避免。解剖变异、炎性癌、复杂形式（穿孔、小肠继发闭塞、周围脓肿、瘘管、门静脉炎、肝脓肿）以及与腹膜炎症反应相关的伴随征象（反射性肠梗阻、反应性回肠炎或输卵管炎）也可能导致误诊。
