Presentarnos dos casos de hernias internas paraduodenales izquier-das localizadas en la fosa de Landzert, diagnosticadas mediante tomo-grafía computarizada (TC).

Las hernias internas son una causa muy infrecuente de abdomen agudo, provocan cuadros de suboclusión intestinal. Las paraduodena-les izquierdas representa alrededor del 50% de las hernias internas.

La TC permite demostrar el grupo de asas herniadas, enmarcadas entre el estómago, la cuarta porción de duodeno, el colon descendente y la cola pancreática. La identificación de las asas en posición atípica, unida a los desplazamientos vasculares (vasos mesentéricos) y colóni-cos que provocan, les confieren una semiología radiológica típica, que una vez conocida se muestra como fácilmente identificable.

Left paraduodenal hernias

We report two cases of left paraduodenal internal hernias located in the fossa of Landzert that were diagnosed by CT.

Internal hernias are an infrequent cause of acute abdomen, due to the intestinal subocclusion they produce. Left paraduodenal hernias are responsible for about 50% of internal hernias.

CT makes it possible to demonstrate the group of herniated loops between the stomach, fourth segment of the duodenum, descending colon, and tail of the pancreas. The identification of the loops in an atypical position together with displaced blood vessels (mesenteric vessels) and colon gives confers on them a typical radiological semiology that makes them easily identifiable.
