One case of wrist cyst rupture with nerve and blood vessel compression

INTRODUCTION AND IMPORTANCE: Tendon sheath cysts are mostly located around the joint capsule and tendon sheath, which often occur in the wrist, ankle, and wrist back (O'Valle et al., 2014; Nguyen et al., 2004 [1, 2]). The palmar side of the wrist is relatively rare, which is often associated with the wrist. Ultrasound and MRI can detect and diagnose early. CASE PRESENTATION: In this case report, we discussed an elderly woman with palmar carpal tendon sheath cyst and ruptured. She communicated with the outside world through the skin sinus, and at the same time pressed the radial artery and the median nerve to produce obvious clinical symptoms. CLINICAL DISCUSSION: Because of its deep position and close relationship with the surrounding important nerves and vessels, the operation was relatively difficult. In particular, in this case, tendon sheath cyst ruptured to form sinus, so there were some difficulties. CONCLUSION: Pathological diagnosis was tendon sheath cyst. The analysis of the relationship between the tumor and the surrounding tissue by preoperative MRI and other imaging examinations has important guiding significance for surgery.
