Intense polymorphic lymphoid infiltration develops with inflammation. The masses in the orbita can be seen by 5% to 8%. It can cause nonspecific orbital symptoms, such as proptosis and swelling on eyelids. In our case, the patients presented to the eye outpatient clinic with swelling complaint and acute atopic conjunctivitis treatment was initiated but the patients who did not regression complaints were submitted. The patient’s magnetic resonance imaging (MRI) showed bilateral lateral rectus muscle thickening. Idiopathic orbital inflammatory syndrome (pseudotumor orbita) responded to the steroid treatment. Idiopathic orbital inflammatory syndrome (pseudotumor orbita) is benign, but can be confusedwith sinusitis complications with high morbidity and mortality.
