LAUSR

examination using a linear transducer with a variable frequency of 10 to 22 MHz. Scanning of the dermis-hypodermis in the longitudinal axis showed a well-delimited, hypoechogenic ovoid lesion with a diameter of 5 mm with posterior reinforcement and an edge shadowing artifact. On the longitudinal axis, the lesion had a uniform, fusiform morphology. Color Doppler ultrasound showed vascularization in the center of the lesion (Fig. 2). Pulsed-wave Doppler showed turbulent flow. The patient was asked to perform the Valsalva maneuver during the examination and we observed a noticeable increase in velocity in the Doppler spectrum (Fig. 3).
