Computed tomography with contrast revealed an enhancing tumor in the area of the right inferior rectus muscle, which appeared in the MRT as an isointense structure in the T1-weighted image. On staging, we found a contrast-enhancing nodular hepatic lesion. In octreotide scintigraphy, enhancement of the liver, thoracic and abdominal para-aortic lymph nodes and of the right inferior orbit was found. The survival times of patients with orbital metastasis of carcinoid tumors range between 7 months and 11 years. No specific treatment is available.
Surgical excision is indicated for a symptomatic solitary metastasis.
Our patient is presently being treated with 200 micrograms of octreotide three times a day subcutaneously. Flush episodes and diarrhea have been reduced, but her ophthalmologic symptoms remain unchanged, and she has recently developed cardiac insufficiency. Fifteen consecutive patients, mean age 57.8 years, were prospectively included between July 1993 and January 1997. Five patients had the carcinoid syndrome. STZ was administered, as an emulsion with iodized oil, into the hepatic artery before embolization with gelatin sponge particles.
