Fig. 1. A. Proptosis and downward, outward globe displacement developed over 2 days in a 3-year-old girl. A homogeneous mass fills the superomedial orbit. B. Contact B-scanning shows a relatively well-circumscribed mass with uniform internal echoes. C. Contact A-scanning shows the internal reflectivity to be of low to medium amplitude, consistent with a sarcomatous lesion. Biopsy results confirmed the diagnosis of rhabdomyosarcoma.
