43-year-old male with right knee pain. Evaluate for right knee mass. Markers were placed along the anterior surface of the knee. Deep to the marker is a mass within the subcutaneous fat anterior to the patella and proximal patellar tendon that measures 4 cm x 2 cm in transverse dimension and 4 cm in craniocaudal dimension. It is predominantly of fluid signal intensity with small internal septations on T2-weighted images. There is peripheral rim enhancement on postcontrast sequences. Edema extends both superiorly and inferiorly from the mass within the anterior subcutaneous fat. The extensor mechanism itself appears normal.There is a small multilobular mass with internal septations posterior to the distal femoral metaphysis which shows no apparent enhancement and likely represents a ganglion. MENISCI: There is increased signal intensity along the undersurface of the peripheral fibers of the posterior horn of the body of the medial meniscus. While it is conceivable that this could represent a shallow undersurface tear of the vascularized periphery of the meniscus, it may simply represent signal averaging with normal juxtameniscal tissue and is not necessarily of any current clinical significance. The remainder of the medial meniscus appears normal. The lateral meniscus appears normal.ARTICULAR CARTILAGE AND BONE: The articular cartilage and bone appear normal. LIGAMENTS: The cruciate and collateral ligaments appear intact. ADDITIONAL
Prepatellar bursitis and other findings as described above.
