Falling snow sign (spermatocele)

Last revised by Dr Henry Knipe on 29 Sep 2022

The falling snow sign describes the appearance of movement of internal echoes in spermatoceles away from the transducer, resulting in an appearance similar to falling snow when color Doppler is applied. The sign can be used to aid in the diagnosis of a spermatocele.
