Se comunican dos tumores neuroendocrinos pancreáticos, un insulinoma y un glucagonoma. Basados en esta experiencia se revisan las distintas técnicas que posibilitan la localización del tumor y sus eventuales metástasis, como son los untrasonidos, laTAC, la RM, la angiografía, la ultrasonografía endoscópica y la gammagrafía con I111-pentatreotide. Se hace notar la conveniencia de comenzar por los procedimientos menos invasivos como son laTAC y la gammacámara con octreotide.
We present two cases of neuroendocrine tumors: insulinoma and glucagonoma. Several diagnostic procedures are analysed including those useful to localize the tumor and its possible metastasis, as ultrasound, computed tomography, magnetic resonance imaging, angiography, endoscopic ultrasonography and somatostatin receptor scintigraphy. We suggest that the work up should begin with lesser invasive procedures such as CT and In111-labelled pentetreotide scan.
