This 13 year old girl presented with vague abdominal pain and nausea. The patient went to surgery 2 days after the CT and MRI shown here. What did the surgeon find?

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.
