Magnetic Resonance Imaging Double Popliteus Tendon Sign: A Case Report

The double popliteus tendon sign is seen on sagittal magnetic resonance imaging (MRI) of the knee as a low-signal-intensity band parallel to the popliteus tendon at the level of the popliteus hiatus. It is the result of a displaced complex flap tear of the lateral meniscus. This type of displaced me...

Sumario:The double popliteus tendon sign is seen on sagittal magnetic resonance imaging (MRI) of the knee as a low-signal-intensity band parallel to the popliteus tendon at the level of the popliteus hiatus. It is the result of a displaced complex flap tear of the lateral meniscus. This type of displaced meniscal tear can be easily missed on MRI, unless the clinician is aware of its existence and significance and is familiar with its MRI appearance.
