A clinical case of Fournier's gangrene: imaging ultrasound.

Fournier's gangrene is a rapidly progressing necrotizing fasciitis involving the perineal, perianal, or genital regions and constitutes a true surgical emergency with a potentially high mortality rate. Although the diagnosis of Fournier's gangrene is often made clinically, emergency ultrasonography and computed tomography lead to an early diagnosis with accurate assessment of disease extent. The Authors report their experience in ultrasound diagnosis of one case of Fournier's gangrene of testis illustrating the main sonographic signs and imaging diagnostic protocol.

[Mammary duct ectasia: nosologic assessment. Features and echographic incidence].

This work was aimed at framing duct ectasia as a nosologic entity and at studying its features and US incidence. Duct ectasia is a generally asymptomatic disorder of the mammary gland, which is usually included in the generic terms of mammary dysplasia, mastopathy, and so on. Nine hundred patients underwent US with a high-definition probe.
