Figure 8a. Tubo-ovarian involvement by peritoneal tuberculosis in a 14-year-old girl. (a) Sagittal T2-weighted MR image shows diffuse nodular thickening of the peritoneum (arrows) with a large amount of ascites. In addition, small nodular lesions (arrowheads) are seen on the surface of the ovary. (b) Axial T2-weighted MR image shows the thickened right salpinx (black arrows) surrounding the ovary (white arrows). The thickened salpinx has low signal intensity. (c) Axial contrast-enhanced fat-suppressed T1-weighted MR image shows good enhancement of both thickened salpinges (white arrows), the surface of the right ovary (black arrows), and the peritoneum (arrowheads).
