Primary synovial sarcoma can rarely arise in the rectovesical space, presenting with radiological features such as intervening septa, vascular channels, and signal heterogeneity on CT and MRI.
Case Report (n=1)
This case report highlights the rare occurrence of primary synovial sarcoma in the rectovesical space and its radiological findings.

May warrant inclusion in the differential for heterogeneous rectovesical masses; extends reported sites of synovial sarcoma but remains hypothesis-generating.
Synovial sarcoma is the fourth most common type of soft tissue sarcoma (1). It most commonly arises in the extremities and other locations, but in rare cases can arise in the extraperitoneal space (2). Most extraperitoneal synovial sarcomas that were reported arose in the abdominal retroperitoneum (3). Here, we report a case of primary synovial sarcoma arising in the rectovesical space. We present the radiological findings of this disease and discuss the relevant literature review.

Kil et al. (2011) conducted a case report in Synovial sarcoma in the rectovesical space (n=1). Mass excision, partial cystectomy, and cystoplasty was evaluated. Primary synovial sarcoma can rarely arise in the rectovesical space, presenting with radiological features such as intervening septa, vascular channels, and signal heterogeneity on CT and MRI.
