Standardized echography in the differentiation of orbital lesions

Standardized echography is a unique method of ultrasound diagnosis which complements computed tomography in the evaluation of orbital disease. While computed tomography provides excellent topographic depiction (location and shape) of most orbital masses, the dynamic standardized echographic examination frequently implies a specific tissue-type diagnosis. Both computed tomography and standardized echography were performed on a 66-year-old man with 4 mm of painless, unilateral proptosis. The results are discussed.
