Peripheral vascular malformations (PVMs)

Musculoskeletal arteriovenous malformations (AVM) are typically congenital, growing with age and may not manifest until adolescence or adulthood. Spinal AVMs are discussed separately.

Rarely they can be acquired e.g. post traumatic vascular malformation.

Clinical presentation

Patients can present with a palpable mass (with or without erythema or a thrill) and/or pain ^1-3.

Pathology

Musculoskeletal AVMs can occur within ²:

soft tissues
- subcutaneous
- intramuscular
- intermuscular fascia
joints
- repeated intra-articular bleeds can produce degenerative change similar to haemophilic arthropathy ³
bone: rare; mostly craniofacial with appendicular skeletal even more rarely involved ⁴
