title: Unusual hyperechoic ultrasound appearance of testicular Leydig cell tumour.
abstract: Patients with a testicular mass are usually investigated by ultrasound and the ultrasound appearances have been correlated with the histology. The authors describe two patients with Leydig cell tumours. The first had bilateral tumours which although histologically typical of Leydig cell tumours, had differing ultrasound appearances, one with a previously unreported hyperechoic appearance. The second patient had an impalpable tumour with similar ultrasound appearances to those previously described. The paper illustrates the difficulty of giving an accurate diagnosis of solid testicular lesions and also shows that the previously described appearance of Leydig cell tumour is not pathognomonic.
