Table 1 Principle of TART lesions score.
From: Infertility risk assessment with ultrasound in congenital adrenal hyperplasia male patients
US features | Score | Explanation |
|---|---|---|
Range | 1 | Lesions are not detectable by scrotal ultrasound |
2 | Aggregated oval lesions (one, or separate multiples) in the mediastinum, involving no more than 1/3 of the testis on both transverse and sagittal sections | |
3 | The lesion fills the mediastinum and does not involve more than 1/3 of the transverse and sagittal of the testis; or the lesion does not fill the mediastinum, but involves more than 1/3 of the transverse or sagittal of the testis | |
4 | Under the circumstance of all the mediastinal involvement, the lesion on the transverse involves more than 1/3 of the testis with residence of normal testicular tissue | |
5 | Diffusely growing lesions without normal testicular tissue | |
Echogenicity | 1 | Homogeneous hypoechogenicity |
2 | Heterogeneous hyperechoic | |
3 | Heterogeneous hyperechoic with calcification | |
Vascularity | 1 | Abundant linear blood flow signals filling the entire lesion |
2 | Moderate linear blood flow signals occupying part of the lesion | |
3 | None blood flow or very few around lesion |
