Summary
A rare case of segmental renal infarction was caused by a traumatic dissecting hematoma in a renal artery branch. Aneurysmal dilatation on renal arteriography suggested traumatic arteriopathy, mimicking a tumor on imaging.
Area of Science:
- Nephrology
- Vascular Surgery
- Radiology
Background:
- Renal infarction can result from various causes, including thromboembolism and dissection.
- Traumatic arteriopathy of segmental renal arteries is uncommon.
- Imaging findings can sometimes mimic other renal pathologies, such as tumors.
Observation:
- A case of segmental renal infarction was observed.
- Cross-sectional imaging revealed atypical features, mimicking renal tumors.
- Renal arteriography showed aneurysmal dilatation of a segmental renal artery branch.
Findings:
- The segmental renal infarction was attributed to a traumatic dissecting hematoma of a renal artery branch.
- Aneurysmal dilatation of the affected segmental renal artery is a highly suggestive finding of traumatic arteriopathy.
Implications:
- This case highlights the importance of considering traumatic arteriopathy in the differential diagnosis of renal infarction with atypical imaging features.
- Accurate diagnosis through renal arteriography is crucial for appropriate management of traumatic renal artery injuries.
