Scintigraphy of the orbit with 67Ga-citrate.
The orbits of 50 patients with unilateral exophthalmos have been scanned with 67Ga-citrate. Of the 14 cases of malignant neoplasms in this series, only three cases did not show deposits in a characteristic manner. Some of pseudo-tumours showed patterns characteristic of malignant neoplasmas. 67Ga uptake of cavernous haemangioma was very low compared to the surrounding normal tissues.
