title: Computed tomography (CT) of orbital pseudotumour.
abstract: Orbital pseudotumour is a non-specific inflammatory disease. Its highly variable clinical and radiographic presentation makes specific diagnosis difficult. This study on 31 proven cases of pseudotumour shows that unilateral involvement, retroorbital fat infiltration and enlargement of multiple extraocular muscles with involvement of the tendinous insertions are key computed tomography CT features which help to establish the diagnosis of orbital pseudotumour.
