Regression of orbital hemangioma detected by echography.
Two infants had orbital cavernous hemangioma that showed impressive regression documented by ultrasound follow-up. In a 15-week-old infant the hemangioma regressed from a size of 11.49 mm to 5.36 mm in prominence during a six-month period. In a 9-month-old infant the mass regressed from 8.53 mm to 4.6 mm during a six-month period. These cases demonstrate that orbital cavernous hemangioma in infancy occasionally shows impressive regression. Furthermore, they illustrate the value of orbital ultrasonography in defining the natural history of orbital hemangioma. Similar follow-up studies in large numbers of infants with orbital hemangioma are needed to further our understanding of the natural history of this tumor.
