Summary
Renal lymphoma often presents as multiple kidney masses on CT scans, even without enlarged lymph nodes. Consider lymphoma in patients with unexplained renal or perirenal masses.
Area of Science:
- Radiology
- Oncology
- Nephrology
Background:
- Renal lymphoma is a rare condition.
- Accurate diagnosis is crucial for timely treatment.
Purpose of the Study:
- To identify CT imaging patterns of renal and perirenal lymphoma.
- To improve diagnostic accuracy for renal lymphoma.
Main Methods:
- Retrospective review of CT studies.
- Analysis of 29 patients with renal or perirenal lymphoma.
- Identification of distinct disease patterns.
Main Results:
- 59% of patients had bilateral renal masses.
- 28% had single lesions contiguous with lymphadenopathy.
- No diffuse renal involvement without focal mass was observed.
Conclusions:
- Renal lymphoma can manifest as multiple homogeneous renal or perirenal masses.
- Consider lymphoma even without apparent retroperitoneal lymphadenopathy.
- CT findings can aid in early diagnosis of renal lymphoma.
