Cyamella gigante: um raro sesamoide

Here, we report the case of a 46-year-old male who present-ed with a three-year history of pain in the right knee. He stated that he had experienced no trauma or torsion, had not under-gone any surgery, and did not engage in sports. In the physical examination, he tested positive for a meniscal tear. Magnetic resonance imaging (MRI) revealed a giant cyamella; complex rupture of the body and anterior horn of the lateral meniscus; and chondral lesions in the lateral femorotibial compartment (Figure 1).Sesamoid bones are accessory ossicles located in the ten-dons and muscles; their function is to facilitate the physiologi-cal movement of the tendon, although they can, in some cases, cause disease
