The pentad of abdominal pain, pyrexia of unknown origin, malaise, weight loss, and nausea remains the most convincing presentation of mycotic aneurysms of the SMA and IMA. Computed tomography is the investigative modality of choice, and such patients are best served with aneurysmectomy alone in IMA aneurysms and interposition vein grafting in SMA aneurysms after initiation of antimicrobial therapy on suspicion of the diagnosis.

AS is self-limiting and a non-urgent surgical condition. It can be differentiated from other pathologies by clinical spectrum, patient demographics and in doubtful circumstances (acute limb ischemia) by Doppler sonography. An algorithmic approach can avoid hospital admissions, partially unnecessary investigation and assist in patient assurance.

Mesenteric avulsion is rare and has a complex and vague presentation. Due to its potential mortality and morbidity, emergency physicians should keep a high index of suspicion in individuals with blunt abdominal trauma from any mechanism of injury.
