Hemorrhage into a juxtafacet cyst is rare and cyst rupture with hemorrhagic extension into the epidural space is even less commonly seen. We describe the case of a patient with a hemorrhagic synovial cyst with rupture associated to abundant bleeding in the epidural space. A 61-year-old man had a 5-month history of worsening low back pain radiating into the right leg with associated weakness and numbness. A magnetic resonance imaging scan showed the presence of a mild anterior spondylolisthesis of L5 on S1 with increased synovial fluid into both facet joints. A suspected synovial cyst of the right facet joint at level L5-S1, with signal characteristics consistent with hemorrhage was seen. Caudally, epidural blood was evident from S1 to S2 that involved spinal canal and right S1 and S2 foramens. These findings were confirmed at surgery.

Synovial fistula of the knee occurs when a defect in the joint capsule creates a connection between skin, bursa, and a near tissue, manifesting as an opening with continuous draining fluid or a cyst. This is a case of an 80-year-old male who developed a synovial fistula with cystic presentation 6 years after the primary total knee arthroplasty. Management included a total knee arthroplasty revision surgery with intraoperative identification of the fistula with methylene blue, and using a gelatin-thrombin matrix for closure.
