Johns Hopkins Pathology
Key Points:
  • Sharply circumscribed hypodense lesions
Images: Solid-pseupapillary neoplasm |

On CT scans, solid-pseudopapillary neoplasms appear as sharply circumscribed hypodense lesions. The cysts have fluid-debris levels and peritubular capsules. SPN’s, if small, show no cystic change and appear as pancreatic endocrine neoplasms; larger SPN's will show cystic areas as well as solid areas. On MRI, SPN’s are sharply demarcated and have areas of high signal intensity corresponding to foci of hemorrhage on T1-weighted images.
