B: Coronal T1 weighted image demonstrates the pancreatic mass with central necrosis and peripheral enhancement.

B: Axial LAVA post contrast T1 weighted image demonstrates the pancreatic mass with central necrosis and peripheral enhancement.

 

Discussion:

Solid pseudopapillary tumor of the pancreas (SPT) is a rare neoplasm of the pancreas seen predominantly in young Asian and African-American females between ages 10 and 20. Although most tumors are benign, about 15% may be malignant. As in this case, CT and MRI usually demonstrate a peripheral enhancing large mass. MRI shows heterogeneity on all sequences due to necrosis and hemorrhage. Differential diagnosis includes serous cystadenoma, mucinous cystic neoplasm, islet cell tumors, and pancreatoblastoma. Complete surgical resection is usually curative.
