| Abstract: | Objective To evaluate the diagnostic value of MRI in solid-pseudopapillary tumor of the pancreas （SPTP）. Methods MRI features of 9 patients with histopathologicaly proved SPTP were retrospectively analyzed. All 9 cases underwent MRI plain and contrast enhanced examination. Results 8 cases were cystic-solid mass. 1 case was pure solid mass. 7 cases had complete capsule. 8 cases of the tumors showed mixed signals. 6 cases had hyper intense on TIWI. In post-contrast scan, solid portions appeared mild heterogeneous enhancement on arterial phase and progressive fill-in during the portal venous and equilibrium phases. Conclusion The MRI features of SPTP are characteristic. MRI is valuable for the diagnosis and differential diagnosis. |
