title: Unilateral proptosis with thyrotoxicosis resulting from solitary retroorbital soft tissue metastasis from follicular carcinoma thyroid.
abstract: Unilateral proptosis can be of neoplastic origin, even if the results of thyroid function tests suggest hyperthyroid disease, and it needs proper investigation with a computed tomographic scan of the orbit. The authors present a case of left-sided proptosis resulting from a metastasis in the retroorbital soft tissue from follicular carcinoma of the thyroid. A nodular goiter involving the left lobe and isthmus was found. The initial thyroid function test values suggested hyperthyroid disease and the patient had clinical signs of toxicity. A computed tomographic scan of the orbit revealed a left-sided retroorbital soft tissue mass, part of which was resected and found be to a metastasis from follicular carcinoma of thyroid. Total thyroidectomy was performed and the patient was treated with I-131 after operation. The proptosis resolved with I-131 treatment.
