TitleOrbital lymphangioma treated with intralesional injection of sodium morrhuate.
PurposeTo describe the efficacy of the injection of the sclerosing agent sodium morrhuate in orbital lymphangioma.
Orbital lymphangiomas often cause disfiguring proptosis with recurrent painfull hemorrhages and risk of vision loss. Surgical removal is almost always incomplete and associated with considerable risks.
Other sclerosing agents have been described with variable success, but also with serious orbital inflammation and even blindness. Sodium morrhuate has only been described once.
MethodsCase report. A 6 year old boy presented with a sudden unilateral painless proptosis of 8 mm compared to the other eye. VA was 0.8 bilaterally. Imaging revealed an intraconal lymphangioma with internal hemorraghe. The following 3 months proptosis increased slowly to 10 mm, with diplopia and VA decreased to 0.6. One month later he presented with a swollen caruncula. Proptosis had increased to 15 mm, VA was 0.5 with moderate optic disc swelling en retinal venous dilatation.
The largest orbital cyst was punctured under CT guidance. Yellow clear fluid was aspirated, followed by injection of water soluble contrast, which remained confined to the orbit and did not enter the cavernous sinus. Finally 0,8 mm of sodium morrhuate was injected in the orbital lesion.
ResultsThere was no postoperative inflammation and proptosis was unchanged. Proptosis reduced to 5 mm after one month, 4 mm after 3 months and remained stable since.
ConclusionThe intralesional injection of sodium morrhuate in orbital lymfangioma did not induce any visible external orbital inflammatorion and was efficient in reducing proptosis.
