description

A case of intramuscular orbital myxoma and of a schwannoma of the orbit were studied with B-scan and standardized A-scan echography as described by Ossoinig. The myxoma appeared as a well outlined process with medium internal reflectivity and areas of low internal reflectivity. Postoperatively the incompletely excised tumour was followed with echography as well as CT and MRI. The second tumour, a schwannoma had a very sharply defined shape, with a thick low to medium reflective outer wall and low internal reflectivity. This corresponds to the Antoni A and Antoni B patterns of the excised tumour.
