Orbital venous malformation

Case contributed by A.Prof Frank Gaillard

The mass initially fills in posteriorly as contrast sinks dependently, and enlarges on valsalva. It has a multilobulated/septated appearance with a periphery that does not fully enhance.

Findings are those of a low flow venous malformation.

Case Discussion

This patient had a vascular malformation - lateral orbitotomy - 7 years previously, with recurrence.

The mass initially fills in posteriorly as contrast sinks dependently, and enlarges on valsalva. It has a multilobulated/septated appearance with a periphery that does not fully enhance.

Findings are those of a low flow venous malformation.

The distinguishing features between this entity and a orbital venous varix (OVV) are:

  • slow enhancement - later than veins
  • incomplete enhancement
  • multilobulated/septated appearance
