[Pitfalls in scrotal echotomography].

We reviewed 500 scrotal sonograms with a gray-scale equipment using a 7 Mega Hertz transducer. 7 cases are presented in which there are the two principal traps which must be avoided in the practice of scrotal ultrasound: To find as pathological, some scrotal or parascrotal structures which are anatomical. To confuse pathological images. These diagnostic problems are almost resolved by three conditions: A perfect knowledge of normal ultrasound anatomy, a good experience of the operator in this scope and a strict management of the ultrasonic investigation. There, the scrotal sonogram is highly reliable.
