Overview
Other Imaging Findings
Arteriography
- Arteriography is the best imaging study to diagnosis of PAN.
- Findings on an arteriography diagnostic of PAN include:[1][2]
- Microaneurysms
- Pathognomic finding seen in 60-80% patients.
- Caused by rupture of a vessel wall due to necrotizing inflammatory process.
- Most commonly seen at the branching points and bifurcations of arteries.
- Microaneurysms are usually more than 10 in number.
- Size: 2-5mm
- Saccular aneurysms
- Size: 1-5mm
- Seen in small and medium sized vessels.
- Tortuous vessels showing:
- Irregular lumina
- Segmental luminal narrowing or dilatation
- Infarctions
- Vascular irregularity
- Segmental occlusions
- Microaneurysms
