Intercisternal cysts are generally defined as cysts of the interosseous muscle, which can usually be observed without treatment and then operated on if necessary.
The piriformis muscle is abundant, and when the palm of the hand is stretched out, it protrudes significantly and occupies a large area of the palm of the hand. If the cyst is asymptomatic and does not affect your life, observation is sufficient and no special treatment is needed.
If the cyst becomes uncomfortable or affects life and aesthetics, it can be removed through outpatient surgery under local anesthesia. However, if there is a combination of ulceration or pus flow, appropriate use of antibiotics (such as penicillin, cephalosporins, etc.), or even a phase I incision and drainage followed by phase II surgical suture.
It is recommended that the patient should consult the doctor in time, and the doctor should consider the treatment mode with the actual situation, do not blindly self-medication.
