Pseudotumor of the orbit.

Pseudotumor of the third most common ophthalmologic disease after Graves' disease and lymphoproliferative disease. It is usually a continuous illness, although recurrent forms do occur, especially in the pediatric age group. The radiologic evaluation consists of computed tomography and magnetic resonance imaging. The imaging findings, correlated with the clinical findings, allow a diagnosis in most cases and, hence, obviate the need for a biopsy.
