Medulloblastoma Metastatic to the Pancreas: A Case Report

We present a case of metastatic medulloblastoma to the pancreas in a 41-year-old woman with recurrent cerebellar medulloblastoma. Upon presentation, CT of the abdomen and pelvis showed a 2.2 x 2.6cm hypodense pancreatic head mass associated with obstruction of the pancreatic duct. Endosonography with fine needle aspiration (EUS-FNA) was performed with cytology showing a malignant small cell neoplasm consistent with medulloblastoma, morphologically identical to the primary cerebellar medulloblastoma. Metastatic medulloblastoma to the pancreas is an extremely rare form of a secondary pancreatic tumor, with very few case reports in the literature. The diagnosis rests upon comparison of the cytological features when both primary and secondary tumors are available.
