A patient presented with unilateral proptosis which was compressible and increases on bending forward. No thrill or bruit was present. MRI shows a retroorbital mass with enhancement. The likely diagnosis is –
a) AV malformations
b) Orbital encephalocoele
c) Orbital varix
Correct answer : c) Orbital varix
Proptosis that increases with Valsalva manouvre or bending forwards is probably due to vascular lesions such as orbital varix.
