Abstract
Thyroid hemangioma is very rare, with only 13 cases previously reported in Japan, as retrieved by an on-line search.
The patient was a 79-year-old male who had a soft mass measuring 31 mm in diameter in the right lobe of the thyroid. The ultrasonography showed a mass with irregular-shape, low echogenicity and heterogeneity. Although an aspiration biopsy cytology of the mass revealed no malignancy, the findings of the images made us consider the possibility of follicular neoplasm of the thyroid. Right hemithyroidectomy was performed on suspicion of thyroid cancer. The pathological examination revealed cavernous hemangioma in the thyroid gland.
