Orbital myositis simulating infectious cellulitis: report of two cases.
Two cases of orbital myositis simulating infectious cellulitis were reported, in which the diagnosis was made by CT scans, biopsy and laboratory findings of thyroid function. In both cases, ophthalmoscopy revealed partial occlusion of the central retinal vein and choroidal folds due to posterior scleritis. Histopathology of a biopsy specimen revealed infiltration of lymphocytes, eosinophils and plasma cells and perivasculitis which suggested an allergic origin of this disease.
