Acute mesenteric ischemia is a serious condition associated with high mortality. Multislice CT and magnetic resonance angiography have proved accurate in diagnosing this pathology, which requires a prompt diagnosis to start appropriate therapy. We report the case of an 87-year-old woman with acute mesenteric ischemia, in whom contrast-enhanced sonography visualized the occluded superior mesenteric artery and the infarcted portion of the intestine.
Neuroendocrine tumors are the most common primary tumors of the small bowel, but diagnosis is usually delayed as the lesions are small and symptoms are mild or nonspecific. Diagnosis of this disease is currently based on radiologic or endoscopic findings. Ultrasound (US) is used as a first-line examination in patients with abdominal symptoms, as this technique permits an overall view of the gastrointestinal tract providing diagnosis of inflammatory and/or neoplastic disorders in a large proportion of patients. The aim of this case report is to describe the feasibility and diagnostic accuracy of elastography in the diagnosis of a tumor of the ileum. The patient underwent conventional gray-scale US and elastography before surgery and these examinations were repeated postoperatively on the surgical specimen confirming preoperative outcome.Keywords Tumor Á Neuroendocrine tumors Á Small bowel Á Ultrasound Riassunto Il tumore neuroendocrino, tra le neoplasie primitive dell'intestino tenue, è il più frequente, la diagnosi è usualmente tardiva per le piccole dimensioni e per la sintomatologia lieve, poco specifica. La diagnosi di questa forma morbosa si basa attualmente su metodiche radiologiche o endoscopiche. L'ecografia è indagine di primo livello in soggetti con sintomatologia addominale ed in una percentuale di soggetti permette anche lo studio del tubo digerente e la diagnosi di patologie neoplastiche o infiammatorie. Scopo del lavoro è di descrivere l'utilità della elastografia nella diagnosi di un tumore dell'ileo in cui l'esame ecografico convenzionale ed elastografico sono stati effettuati sul paziente prima dell'intervento chirurgico e successivamente sul pezzo operatorio con conferma dei riscontri precedenti all'intervento.
