RESUMO
A 9-year-old child presented with right eye swelling and bluish discoloration over the periorbital region. MR and CT displayed prominent vessels within the orbit and in the facial region, suggesting a carotid-cavernous fistula. Doppler ultrasound indicated the vascular engorgement was not secondary to a proximal arteriovenous shunt. Arteriography with its inherent time sequence image capability prompted the proper diagnosis of bilateral atresia of the sigmoid sinuses.

Thyroid carcinoma concentrating both Tc-99m sodium pertechnetate and radioactive iodine is a rare occurrence. This report describes such a case. It is somewhat different from previous reports in that the carcinoma had tracer uptake equal to that of the remaining normal thyroid gland on both isotope studies. It also occurred in the pediatric age group and followed external radiation therapy. A review of the pertinent literature is presented.
