Unusual Presentation of Synovial Sarcoma as Meniscal Cyst: A Case Report

Document Type : CASE REPORT


ShafaYahyaian Hopital, Iran University of Medical Sciences, Tehran, Iran


Periarticular cyst and cystic soft tissue lesion around the knee are common. Synovial sarcoma is a rare and malignant soft tissue tumor accounting for approximately 5% of soft tissue sarcoma. A case is presented where a lesion adjacent to the joint line of the knee was diagnosed clinically and on imaging as a meniscal cyst. MRI signal was homogenous and no concomitant meniscal tears were seen. The tissue diagnosis was monophasic synovial sarcoma.
