The hypoechoic normal tendon. A pitfall
B. D. Fornage
Varying results have been reported concerning the echogenicity of normal
superficial tendons. Our recent results using high-resolution real-time
linear-array equipment indicate that the normal tendons display a specific
echogenic longitudinally oriented fibrillar pattern. However, the
visualization of this normal texture requires a perfect technique of
examination. The obliquity of the ultrasound beams in relation to the
tendon in longitudinal scans as well as the nonrespect of the strict
perpendicularity of the scanning plane in transverse sections result in an
artifactual hypoechogenicity of the normal tendon. Since hypoechogenicity
has been shown a diagnostic criterion for inflammatory changes in tendons,
the awareness of this pitfall is instrumental in preventing a
false-positive diagnosis of tendinitis.
