Abstract

This article aims to describe the imaging findings for mucinous tumors of the abdomen and pelvis, which have a similar appearance on imaging tests regardless of the organ in which they develop. Due to the high water content of mucus, the appearance of these tumors is generally similar to that of water on ultrasonography, computed tomography, and magnetic resonance imaging. Another common feature of mucin-producing tumors is that calcifications are often present. The rupture of these lesions and accumulation of mucinous material in the peritoneal cavity gives rise to pseudomyxoma peritonei. It is important to identify mucinous tumors because they have a different prognosis and clinical course than non-mucinous tumors and require different management. Depending on their anatomic location and their imaging characteristics, the treatment approach varies from follow-up to radical surgery together with chemotherapy or radiotherapy or both.

Resumen

El objetivo de este artículo es describir los hallazgos en imagen de los tumores mucinosos de abdomen y pelvis que, por su composición, comparten características radiológicas independientemente del órgano de origen. Debido al alto contenido hídrico del moco, generalmente muestran un aspecto similar al agua en la ecografía, la tomografía computarizada y la resonancia magnética. Otra característica común de los tumores productores de mucina es la frecuente presencia de calcificaciones. La rotura de estas lesiones con acumulación de material mucinoso en la cavidad peritoneal da lugar al pseudomixoma peritoneal. La importancia de la identificación de las neoplasias mucinosas radica en el diferente manejo, pronóstico y evolución clínica con respecto a las no mucinosas; en función de su localización anatómica y las características de imagen, la actitud varía desde el seguimiento a la cirugía radical en combinación con quimio y/o radioterapia.
