Article information

La calcificación de las paredes de las venas tributarias del sistema venoso portal, usualmente asociada a hipertensión portal (HTP)1-9no es habitual. La calcificación de los vasos intraesplénicos es excepcio-nal.

Presentamos dos casos de calcificación de vasos intraesplénicos de forma aislada, sin calcificaciones en el eje venoso esplenoportal, en pacientes con cirrosis hepática e HTP. El calcio se observó en la radio-grafía simple de abdomen y en ecografía, aunque sin poder precisar su naturaleza exacta. La tomografía computarizada (TC) identificó ese calcio como estructuras lineales, tubulares y ramificadas, situadas en la pared de los vasos intraesplénicos. La resonancia magnética mostró signos de cirrosis e HTP pero no demostró el calcio esplénico por la li-mitación de esta técnica para observar las calcificaciones. La causa de estas calcificaciones fue la HTP mantenida debido a una hepatopatía crónica de larga evolución.

Calcification of the walls of the veins of the portal vein system, usually associated with portal hypertension (PHT) (1-9), is uncommon. Calcification of the intrasplenic vessels is exceptional.

We report two cases of isolated calcification of intrasplenic vessels, without calcification of the splenoportal venous axis, in patients with liver cirrhosis and PHT. The calcification was visible in plain radiography and echography, although its exact nature was not clear. Computed tomography identified the calcification as linear, tubular, branched structures located in the wall of intrasplenic vessels. Magnetic resonance imaging disclosed signs of cirrhosis and PHT but did not show the splenic calcifications because of technical limitations. The cause of these calcifications was sustained PHT due to chronic liver disease.
