Ultrasound features of diffuse sclerosing variant of papillary carcinoma of the thyroid / 中华超声影像学杂志

ABSTRACT

Objective To evaluate the ultrasound(US) features of diffuse sclerosing variant (DSV) of papillary carcinoma of the thyroid. Methods The US and histopathlogical of 20 DSV patients were retrospectively assessed. Results Among the 20 cases,thyroid single lobe of 12 cases,bilateral lobes of 8 cases and cervical lymph nodes metastases of 18 cases (90%) were involved in DSV of papillary carcinoma of the thyroid. At ultrasound, echo diffuse abnormal change of single lobe or bilateral lobes of thyroid and diffuse scattered microcalcifications were seen in the DSV of papillary carcinoma of the thyroid. The blood flow signals of the abnormal lobes were occupied by 75% of one grade and 25 % of two grades. Conclusions DSV of papillary carcinoma of the thyroid is usually manifested as echo diffuse abnormal change,diffuse scattered microcalcifications and cervical lymphocytic infiltration on ultrasound in relatively young patients.
