Abstract:
Three cases of mycotic aneurysm of the renal artery are presented, all of which manifested similar findings on excretory urography and renal arteriography: small intrarenal aneurysm with distal occlusion, corresponding nephrographic defect or defects on urography and arteriography, and opacification of a normal collecting system. To the authors' knowledge these findings have not been reported previously, and they appear to represent a distinctive combination of findings diagnostic of mycotic aneurysm. The significance of recognizing this pattern, particularly as an aid in establishing an early diagnosis of infective endocarditis, is stressed.
Insights
This study presents a unique pattern of renal artery mycotic aneurysms diagnosed via imaging. Early recognition of this pattern aids in diagnosing infective endocarditis.
Area of Science:
- Radiology
- Vascular Surgery
- Infectious Diseases
Background:
- Mycotic aneurysms of the renal artery are rare but serious conditions.
- Diagnosis often relies on a combination of clinical suspicion and imaging.
Observation:
- Three cases of renal artery mycotic aneurysm demonstrated consistent imaging findings.
- These included small intrarenal aneurysms with distal occlusion.
- Associated findings were nephrographic defects and normal collecting system opacification.
Findings:
- A distinctive combination of excretory urography and renal arteriography findings was observed.
- This pattern included small intrarenal aneurysms with distal occlusion.
- Nephrographic defects and normal collecting system opacification were also noted.
Implications:
- This specific imaging pattern may be diagnostic of mycotic aneurysm.
- Early diagnosis of renal artery mycotic aneurysms is crucial.
- Recognizing this pattern can facilitate early diagnosis of infective endocarditis.
