Size: about 34 x 23 x 20 mm.
Morphology: Hypoechoic/anechoic with echogenic multiple echogenic linear bands. There is no calcification. It shows lobulations. There is posterior acoustic enhancement present. The lesion is not significantly compressible.
Doppler: Significant Arterial flow is noted in the lesion. Digital artery is deep to the proximal part of the lesion. Digital artery passes through the distal part of the lesion.
