Abstract

We present the case of a 22-year-old patient with chronic medial pain in the left knee, initially interpreted as a meniscal syndrome, who was later diagnosed with intra-articular synovial sarcoma (SS) after undergoing various diagnostic studies. Magnetic resonance imaging (MRI) at the time of consultation revealed a well-circumscribed, homogeneous mass with nonspecific characteristics in the medial compartment of the knee. Subsequent histological examination confirmed that the lesion was a synovial sarcoma originating from the synovial membrane. After review by a multidisciplinary team, wide resection of the lesion was performed,followed by ligament and capsular reconstruction. Synovial sarcoma is a rare mesenchymal tumor, accounting for less than 10% of soft tissue sarcomas. Its nonspecific MRI characteristics, along with ambiguous symptoms, make early diagnosis challenging. This condition should be considered in the differential diagnosis of nonspecific joint pain, especially when imaging findings do not align with more common pathologies.
