Lateral collateral ligament tear of the knee: appearances on bone scintigraphy with single-photon emission tomography.

We report two cases, with magnetic resonance imaging correlation, of acute lateral collateral ligament tear of the knee following trauma with findings on bone scintigraphy with single-photon emission tomography (SPET). The typical bone scan features are presented. In addition, the advantages of the use of SPET in the detection of associated lesions are discussed.
