Imaging Diagnosis of Orbital Cavernous Hemangioma

Objective:To study ultrasound,CT and MRI findings of orbital cavernous hemangioma and investigate their value in the diagnosis.Methods:Ultrasound,CT and MR images were reviewed and analyzed on 30 cases with cavernous hemangioma,which were comfirmed by pathology.Results:Ultrasound displayed the round shape of the tumor,multitude echo,attenuation of sound diminishing,condensability,short of bloodstream signals;CT displayed the location of the tumor at muscular orbitalis cone,soft tissue density,transparent triangular area in orbital apex,and progressive enhancement by dynamic enhancement;MRI was particularly useful in revealing the relationship of tumor with the ocular muscles and optic nerve.Conclusion:Since ultrasound can reveal the histological category of the tumor and CT and MRI can locate exactly,it is suggested to diagnose cavernous hemangioma by combining CT or MRI with ultrasound.
