This study reports two rare cases of multifocal venous vascular malformations (VVMs) affecting the orbit, head, neck, and limbs. These findings highlight a previously undocumented association of VVMs across diverse body regions.

Area of Science:

  • Vascular Surgery
  • Radiology
  • Dermatology

Background:

  • Venous vascular malformations (VVMs) can affect various body regions.
  • Previous literature has described VVMs in the orbit, head, and neck.

Observation:

  • Two cases of multifocal, low-flow VVMs involving the orbit, head, neck, and peripheral limbs are presented.
  • Patients exhibited distensible lesions in response to Valsalva maneuver or dynamic maneuvers.
  • Imaging revealed bilateral orbital VVMs and associated developmental venous anomalies in the brain in one case.

Findings:

  • This is the first report documenting the association of orbital, cervicofacial, and peripheral limb VVMs.
  • The presented cases demonstrate a rare multifocal VVM pattern.
  • VVMs were characterized as low-flow and benign, with symptoms primarily due to mass effect.

Implications:

  • These findings expand the understanding of VVM distribution and presentation.
  • Highlights the importance of considering widespread VVMs in diagnosis.
  • Suggests conservative management for VVMs without sight-threatening complications.
