Orbital pseudotumor represents a benign inflammatory disorder of the orbit, with unspecified etiology, whose clinical presentation can mimic the ocular pathology of Basedow disease, namely Graves’ ophthalmopathy, the two of them representing two of the most common orbital conditions. Imagistic methods and laboratory analyses can establish the diagnosis through orbital MRI images specific for the orbital pseudotumor, especially by dosage of the TSH receptor antibodies (TRAb) which will have increased values in Basedow disease with ocular damage. In both situations, the treatment is represented as a first therapeutic line by administration of corticotherapy in high dosage orally or intravenously, with favorably evolution, which is also observable in the case of our patient who was diagnosed with orbital pseudotumor based on MRI images, with associated thyroid dysfunction with negative TRAb, in which the pulse therapy with Solumedrol has determined the improvement of ocular symptoms and signs.
