25-year-old female with bilateral knee pain and stiffness and swelling. MENISCI: The medial and lateral meniscus appear intact.ARTICULAR CARTILAGE AND BONE: No full-thickness or near full-thickness articular cartilage defects are identified. No bone marrow signal abnormality is identified.LIGAMENTS: The cruciate and collateral ligaments appear intact. Note is made of lobulated foci of fluid signal intensity along the anterior aspect of the posterior cruciate ligament measuring approximately 3.5 x 1.5 cm, which may represent ganglion formation or mucoid degeneration of the PCL. Parameniscal cyst formation is considered less likely as no underlying meniscal tear is evident. The PCL appears intact.EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Lobulated foci of fluid signal along the posterior cruciate ligament which may represent ganglion formation or mucoid degeneration of the PCL. Parameniscal cyst formation is considered less likely as no underlying meniscal tear is evident. 2. Nonspecific subcutaneous edema along the anterior aspect of the patella.
