Article information

Los tumores del estroma del tracto gastrointestinal engloban una serie de neoplasias que representan del 1% al 3% de todos los tumors digestivos. Cuando asientan en el estómago su tendencia a crecer exofíticamente obliga al diagnóstico diferencial con otros tumores gástricos (linfoma, adenocarcinoma exofítico) y con masas extradigestivas. Presentamos un caso que muestra la dificultad en el diagnóstico por imagen de estas lesiones y la importancia que tienen las técnicas radiológicas modernas (TC helicoidal y RM) y la adecuada interpretación por el radiólogo para orientar al patólogo y al clínico hacia el diagnostic y su adecuado tratamiento.

Stromal tumor of the gastrointestinal tract encompass a group of neoplasms representing 1% to 3% of all digestive system tumors. When located in the stomach, their tendency to exhibit an exophytic growth pattern makes it necessary to establish the differential diagnosis with respect to other gastric tumors (lymphoma, exophytic adenocarcinoma) and nongastrointestinal masses. We present a case that illustrates the difficulties associated with the imaging diagnosis of these lesions and the importance of modern radiological techniques (helical computed tomography and magnetic resonance) and the correct interpretation on the part of radiologists to orient pathologists and clinicians toward the diagnosiss and proper treatment.
