Abstract

Primary pancreatic lymphoma is a rare extranodal manifestation of any histopathologic subtype of non-Hodgkin's lymphoma that predominantly involves the pancreas, and it comprises less than 0.5% of all pancreatic malignancies. Histopathologically, most primary pancreatic lymphomas are the B-cell phenotypes, and T-cell lymphomas are extremely rare. We describe here the ultrasonography and computed tomography (CT) findings of a pathologically confirmed pancreatic T-cell lymphoma in a 37-year-old female patient. Ultrasonography showed diffuse pancreatic enlargement and a slightly bulging mass in the head and tail of pancreas that had markedly heterogeneous echogeneity. The lesion abutted onto the adjacent vessels, but there was no evidence of luminal narrowing or obstruction. The CT scan showed diffuse enlargement of the pancreas and the bulging contoured mass at the pancreatic head and tail with inhomogeneous enhancement, including multiple hypodense areas. It also showed the patent peripancreatic vessels and multiple LN enlargements around the pancreas.
