RESUMO
La invaginación intestinal es una causa poco frecuente de dolor abdominal en adultos. Ocurre en menos del 1% de obstrucción intestinal de delgado. En adultos la mayoría de los casos son el resultado de una lesión intestinal; la invaginación idiopática es extremadamente rara. Presentamos un caso de obstrucción intestinal diagnosticado mediante tomografía computadorizada de invaginación de intestino delgado secundaria a un tumor. Se discute la etiología, diagnóstico y tratamiento de la invaginación intestinal del adulto (AU)
Intussusception is a rare cause of abdominal pain in adults. It occurs in less than 1% of all cases of adult small bowel obstruction. In adult population, most cases are the result of some type of intestinal lesion; idiopathic intussusceptions are an extremely rare occurrence in adults. This report describes one case of intestinal obstruction caused by an intussusception diagnosed by computed tomography(CT) scan. This report discusses the etiology, diagnosis, and treatment of adult intususcepción (AU)

The authors describe the mammographic and B-mode and color Doppler sonographic findings in a breast hemangiopericytoma in a 49-year-old woman. High vascularity was noted on color Doppler scans with the presence of a single vascular feeding pedicle. An update of the literature is included.

We retrospectively analyzed six cases of abdominal cystic lymphangiomas (CL), who had undergone surgical resection. These cases had been evaluated by several modalities: ultrasonography (US), computed tomography (CT), angiography and fine needle aspiration. No age predilection was found. All patients were symptomatic. The most common presenting symptoms were abdominal pain (66%), palpable mass (66%), fever (50%) and vomiting (30%). US showed septations (85%) and unicameral mass (15%); in three cases (50%) echogenic material within the cyst was found, probably due to hemorrhage and infection. CT showed capsular enhancement in all cases. Capsular and septation thickness were slightly increased in cases of infection or bleeding. At CT the contents were usually of fluid attenuation (66%); in 33% the attenuation values were higher, probably because of internal bleeding and infection. US was superior to CT in the demonstration of septations and the internal nature of the cysts. The major role of imaging is to demonstrate the cystic nature of these abdominal masses, because they do not have specific signs or symptoms that could allow a clinical diagnosis.
