Insights
Magnetic resonance (MR) imaging revealed a large B-cell lymphoma in the peripancreatic region of a 38-year-old male. The imaging findings were consistent with the final diagnosis of lymphoma, aiding in patient management.
Area of Science:
- Radiology
- Oncology
- Gastroenterology
Background:
- Peripancreatic masses can present diagnostic challenges.
- Lymphoma is a rare cause of such masses.
Observation:
- A 38-year-old male presented with jaundice and pruritus.
- Magnetic resonance (MR) imaging identified a large, solitary, well-defined peripancreatic mass.
- The mass exhibited mild diffuse heterogeneous enhancement.
Findings:
- The MR appearance of the peripancreatic mass was characteristic of lymphoma.
- The tumor was located at the lateral margin of the pancreatic head.
- No necrosis was observed within the mass.
Implications:
- Accurate MR imaging interpretation is crucial for diagnosing pancreatic region masses.
- This case highlights the utility of MR in identifying non-pancreatic tumors like lymphoma.
- Early diagnosis through imaging facilitates timely and appropriate treatment strategies.
Abstract:
We report the magnetic resonance (MR) appearance of a large B-cell lymphoma in the peripancreatic head region, in a 38-year-old male who presented with a 1-month history of pruritus and jaundice. Routine laboratory examination at presentation revealed an elevated bilirubin. The tumor was a large, solitary well-defined mass with no evidence of necrosis, which showed mild diffuse heterogeneous enhancement. The tumor was closely applied to the lateral margin of the head of the pancreas. The constellation of MR findings was interpreted as consistent with the correct eventual diagnosis of lymphoma.
