Ultrasonographic analysis of peripheral pulmonary lesions in AIDS-related tuberculosis / 中华超声影像学杂志

ABSTRACT

Objective To investigate ultrasonographic characteristics of peripheral pulmonary lesions in AIDS-related tuberculosis,and to discuss their relationship with blood CD4+T lymphocyte level. Methods Ultrasonographic and clinical data of 63 cases of AIDS-related tuberculosis, which were confirmed by ultrasound-guided lung biopsy,were analysed retrospectively. Results Ultrasonographic characteristics classified as solid hypoechoic in 38 cases ( 60.3% ),diffused astral sign in 16 cases ( 25.4% ), and mixed solid-liquid echo in 9 cases (14.3% ).Blood CD4+T lymphocyte count was significantly lower in patients who showed diffused astral sign in pulmonary lesions ultrasonography,than those in patients who showed solid hypoechoic and mixed solid-fluid echo ( P ＜ 0.001 ). Conclusions Ultrasonography of peripheral pulmonary lesions may reveal various imaging characteristics in AIDS-related tuberculosis. The declining level of blood CD4+T lymphocyte count may determine the ultrasonographic features of pulmonary lesions.
