Abstract
Objective: To describe MR imaging features of presumed vascular plexi in the periscapular (PSC) and retroclavicular (RC) locations. Materials/methods: 443 consecutive MR studies performed as “brachial plexus” protocol (axialT1-W and sagittal STIR) were reviewed for presence, size and characteristics of PSC and RC plexi. Results: Presumed PSC and RC vascular plexi were present in 10%. Both plexi more commonly occurred on the left side. Percutaneous biopsy (n = 1) yielded no vascular neoplasm. Conclusion: RC and PSC vascular plexi are commonly encountered on routine brachial plexus MR imaging and may represent variant vascular networks, as they are frequently found on the contralateral asymptomatic side.
