There have been few reports on the imaging characteristics of cryptococcus neoformans (C. neoformans ) infection of the breast. Herein, we reported the imaging features of C. neoformans infection of the breast in a 41-year-old woman with immune thrombocytopenic purpura. Bilateral, diffuse, hyperechoic, and well-defined margin lesions were observed on breast ultrasounds. In addition, a global asymmetry in the left breast, and a focal asymmetry in the right breast were observed on mammograms. Breast fine needle aspiration and biopsy results revealed a C. neoformans infection. After 5 months of treatment with oral fluconazole and amphotericin B, the lesion on the right breast disappeared on repeated-breast ultrasounds.

Mổ khám phi toàn diện đường tiêu hóa của 275 chó nuôi tại 3 xã, phường (xã Thịnh Đức, xã Quyết Thắng, phường Đồng Quang) thuộc thành phố Thái Nguyên đã phát hiện được 5 loài sán dây ký sinh ở chó là: Dipylidium caninum (Linnaeus, 1758), Spirometra erinacei-europaei (Rudolphi, 1819) (Mueller, 1937), Taenia hydatigena (Pallas, 1766), Multiceps multiceps (Leske, 1780), Taenia pisiformis (Bloch, 1780). Tần suất xuất hiện các loài sán dây tại các địa phương dao động từ 33,33 - 100%. Tỷ lệ nhiễm sán dây ở chó tại 3 xã, phường là 32,00%; biến động từ 26,09 - 34,13%, cường độ nhiễm từ 1 - 8 sán dây/chó. Chó ở các lứa tuổi đều nhiễm sán dây, tỷ lệ nhiễm sán dây ở chó giảm dần theo tuổi. Tỷ lệ nhiễm sán dây ở chó cái là 36,36%, cao hơn so với chó đực (29,55%). Tỷ lệ chó nhiễm sán dây trong vụ Xuân - Hè cao hơn vụ Thu - Đông (33,33% so với 30,40%).

This study aimed to describe the diagnostic performance of lung ultrasound (LUS) in detecting and semi-quantifying pneumothorax (PTX), using computed tomography (CT) as the reference standard. The study included 150 patients who underwent CT-guided transthoracic biopsy (TTB) for lung lesions. Within 30 minutes, two radiologists blinded to the participant’s prior information performed LUS in asymptomatic patients. The results showed that PTX was present on CT in 49/150 (32.3%) cases. LUS was positive in 40/150 (26.7%) patients, with a substantial agreement between the two radiologists (Cohen κ statistics = 0.8). The sensitivity and specificity of LUS were 100% (95%CI 97.6% to 100%) and 91.8% (95%CI 87.4% to 96.2%), respectively. Moreover, the positive and negative predictive values were 87.5% (95%CI 82.2% to 92.8%) and 96.4% (95%CI 92.4% to 98.9%), respectively. In the semi-quantification of PTX by LUS, the location of lung point was described in 36/49 (73.5%) patients. The sensitivity and specificity of this sign were 87.5% (95%CI 82.2% to 92.8%) and 96.4% (95%CI 92.4% to 98.9%), respectively. The positive and negative predictive values were 87.5% (95%CI 82.2% to 92.8%) and 96.4% (95%CI 92.4% to 98.9%), respectively. In conclusion, LUS is a susceptible and specific diagnostic method for diagnosing and semi-quantifying PTX.
