Qualitative Elastography in Ultrasound Diagnosis of Small Benign Breast Lesions in Patients with Hypothyroidism
Abstract
Aim: to determine the opportunities of breast ultrasound with qualitative elastography in the diagnosis of small benign Doppler nonvascular lesions in patients with hypothyroidism. Material and methods. In 2010-2013 the study included 319 women aged 20 to 85 years. Mammography and breast ultrasound (US) with qualitative elastography were performed. Mammography used to reveal breast disorders which are background to small benign Doppler nonvascular lesions. Results. Breast US with qualitative elastography allows to differentiate small benign Doppler nonvascular lesions - cysts with dense content and fibroadenomas from 5 to 10 mm. Sensitivity and specificity of breast US with qualitative elastography in diagnosis of cysts with dense content and fibroadenomas from 5 to 10 mm were 88.4%, 89.5% and 88.1%, 90.5% in patients with hypothyroidism and 98.5%, 97.8% and 98.7%, 98.4% in patients without hypothyroidism, respectively. Differential diagnostics of small benign Doppler nonvascular lesions <4 mm with breast US with qualitative elastography quality is complicated. Sensitivity and specificity of breast Us with qualitative elastography in diagnosis of cysts with dense content and fibroadenomas <4 mm were 86.2%, 68.9% and 85.7%, 66.1% in patients with hypothyroidism and 92.6%, 78.3% and 93.9%, 79.3%, in patients without hypothyroidism respectively. The effectiveness of differential diagnostics of small benign Doppler nonvascular lesions in patients with hypothyroidism is lower than in patients without hypothyroidism. Conclusion. Breast US with qualitative elastography usage is advisable combination for small dopplerographic avascular mass larger than 5 mm, both in patients with and without hypothyroidism. Breast US with qualitative elastography is more effective in patients without hypothyroidism than in patients with hypothyroidism.
