OBJECTIVE: The purpose of this series was to describe the sonographic findings of the diffuse sclerosing variant of papillary carcinoma (DSVPC) of the thyroid. METHODS: The sonographic findings of 8 patients with DSVPC of the thyroid were retrospectively analyzed. The following sonographic features of DSVPC of the thyroid were analyzed: extent of disease, echogenicity, microcalcifications, and cervical metastatic lymphatic nodes. RESULTS: Three of 8 cases were unilateral, and 5 were bilateral. All 8 cases showed diffuse involvement of at least 1 entire thyroid lobe. Five of 8 cases showed hyperechogenicity, and 3 showed hypoechogenicity. Seven of 8 cases showed diffuse scattered microcalcifications, and 1 showed locally distributed microcalcifications. All 8 cases showed cervical metastatic lymph nodes. CONCLUSIONS: The sonographic findings of DSVPC of the thyroid are characteristic, and sonography is a useful imaging tool in diagnosis of DSVPC of the thyroid.
