Secondary Raynaud's phenomenon

Case contributed by Dr Roberto Schubert

Presentation

Acral ischaemia in a patient with polyarteritis nodosa.

Patient Data

Age: 70
Gender: Female
Modality: MRI

No detectable perfusion of the arteries of the 5th finger. String-of-beads appearance of the digital arteries II-IV with segmental stenoses. Narrowing of the ulnar artery in Guyon's canal.

Case Discussion

The "strings of beads" probably represent microaneurysms 1.

Although digital subtraction arteriography (DSA) is superior to MRA in acral perfusion disorders for its better temporal and spatial resolution, and the option to inject vasodilative agents, it is rarely indicated in patients with Raynaud's phenomenon.
