Value of ultrasonography in diagnosing tendon xanthoma / 中华超声影像学杂志

ABSTRACT

Objective To evaluate the value of ultrasonography in diagnosing tendon xanthoma.Methods The ultrasonographic images of 17 patients with tendon xanthomas confirmed by surgery and pathology were retrospectively analyzed.The ultrasonographic features were summarized.Results The ultrasonographic images showed the location,number,size,shape,boundary,internal echo,involvement and blood supply of tendon xanthomas clearly.Tendon xanthomas showed hypoechoic masses within the tendons,mostly located on the extensor aspect of the hands,feet or bilateral Achilles tendons,symmetric growth,irregular-shaped and inhomogeneous,with loss of the normal fibrillar pattern in longitudinal plane.The abundant blood flow inside the tendon can be detected by color Doppler examination.Conclusions High frequency sonography is the preferred imaging method for diagnosis of tendon xanthomas.
