Protocolo diagnóstico de las lesiones sólidas pancreáticas

Abstract

Most solid lesions that appear in the pancreas are usually malignant in nature. Ductal adenocarcinoma is the most common, followed by neuroendocrine tumors. Computed tomography (CT) is the radiological test of choice, as it provides information on both the nature of the lesion and its extension. Magnetic resonance studies also have a good diagnostic performance. An endoscopic ultrasound is the test of choice for biopsies, as it will provide a definitive diagnosis and, in addition, has better resolution than a CT scan for small lesions. Solid lesions that appear in the context of chronic pancreatitis or autoimmune pancreatitis may be benign in nature, although both entities entail a higher risk of developing pancreatic tumors. Therefore, the differential diagnosis should be comprehensive.
