| Abstract |
|
Cavernous hemangioma is the venous malformation that most frequently involves the orbit, And in orbital venography, the injection of contrast medium(conray) is made into a branch of frontal vein. The films are taken after delivery of 5 ml and immediately prior to the end of the injection. A preliminary control film is also obtained for this subtraction studies. Recently, authors experienced a case of orbital hemangioma which is caused unilateral proptosis of right eye(6 yr, old boy) and confirmed this patient as an orbital cavernous hemangioma by the technical aid of orbital venography under general anesthesia. Subtraction technique of R. orbital venograms following catheterization of one of the frontal veins revealed that 3rd segment of R. superior ophthalmic vein including 1st and 2nd segments is slightly displaced medially and superiorly of the frontal projection. They were somewhat dilated in caliber. Some dilated and tortuous vessels were filled with contrast media in the inferomedial aspect of the R. oribit from possible Srd segment of SOV. on the R. down lateral projection, there were abnormaly abundant dilated and tortuous vessels in the lateral portion of the orbit. It is fed from the R. angular vein, and CM are drained from the lesion to the dilated IOV at its posterior portion. R transfemoral arteriograms(AP, Lat) showed mild elevation of 3rd portion of the ophthalmic artery superiorly on the lateral projection, but it appeared normal caliber. The supraorbital and muscular branches as well as choroid crescent were not remarkable in this case. R. external carotid angiogram(LAT) showed within normal patterns. Angiographic diagnosis was a large venous malformation involving the lateral and posterior portions of the R. orbit, most likely cavernous hemangioma. Final diagnosis was confirmed by histopathological study of an excised hemangioma. After surgical removal the visual acuity was improved to normal without any disability of the eye. |
