Manual of Diagnostic Ultrasound in Infectious Tropical Diseases - part 8

Siêu âm nội dung bìu trong Bmode với 3,5-MHz thăm dò cho thấy cấu trúc giống như anechoic u nang (mũi tên) tương ứng với lymphangiectasias lớn tại một bệnh nhân bị nhiễm bệnh với W. bancrofti. FDS (không rõ ràng về hình ảnh này) đã được nhìn thấy trong một bạch huyết giãn nở ít hơn (mũi tên nhỏ). Không có thủy tinh mạc đã có mặt | 122 3 Ultrasound Diagnosis of Special Infectious and Parasitic Diseases Fig. 3.57.

Its use to monitor absence of lymphangiectasia in areas where transmission has been interrupted deserves further investigation. Acknowledgement. We
