|Hypervascular pancreatic lesions: pictorial review and differential diagnosis, and pitfalls.|
Hypervascular pancreatic lesions can have multiple causes, some benign, others malignant, and pitfalls are commonly observed . Accurate diagnosis demand proper knowledge, and is crucial to evaluate the need of resection, avoiding unnecessary procedures. The differential diagnosis consists, mainly, of tumors (primary and metastatic) and lesions from adjacent structures, which could mimic a pancreatic disease [1,2].
The lesions may be divided into three groups based on their risk for malignancy: “no-risk” (non-neoplastic lesions like vascular abnormalities and intrapancreatic accessory spleen), “low risk” (solid pseudopapillary tumors and solid-appearing serous cystadenomas, mainly) and “high risk” (mostly acinar pancreatic carcinomas, hypervascular pancreatic metastases and neuroendocrine tumors – NET) [1-3].
Usually the diagnosis demands a computed tomographic (CT) scan or magnetic resonance imaging (MRI) . On this educational exhibition, four suspected cases of hypervascular lesions will be described, including two cases of “no-risk” and two cases of “high risk” lesions, with different radiographic findings, aiming to provide a pictorial review of the subject and encourage further deepened study.
