Application value of ultrasonography in the diagnosis of struma ovarii

Abstract

Objective To investigate the sonographic features and diagnosis values of struma ovarii. Methods The sonographic features of 20 struma ovarii patients diagnosed by pathology from June 2015 to March 2018 were retrospectively analyzed. Results The age of the patients was 29 to 82 (41.5 ± 24.0) years old, and 5 cases were postmenopausal. Ultrasonography showed that ovarian goiter was mainly unilateral and solid-cystic, and most of them were thick partitions. The solid echo was similar to the thyroid gland, and more specific papillary protrusions and honeycomb structures could be found. Some of them could show crystallization speckle echo (high probability of cystic part), and blood flow signal could be seen in most of solid part. The pathological results showed that all cases were ovarian goiter except 1 case of ovarian goiter with local papillary thyroid carcinoma. Conclusions Struma ovarii is characteristic to a certain extent, and ultrasonography is helpful for the diagnosis of the disease.
