Extranodal Non-Hodgkin Lymphoma: A Rare Presentation Involving the Pancreas

Abstract

Non-Hodgkin lymphoma (NHL) is a cancer of the immune system, and accounts for 90% of all lymphomas. When lymphoma is discovered outside of the immune system, it is considered extranodal lymphoma. Any organ can be the primary site of NHL, with the gastrointestinal tract being the most common site of involvement. This case study explores the sonographic discovery of an uncommon presentation of NHL with an extranodal mass originating from the pancreatic body and tail, and further extending into the splenic hilum.
