You may be using the wrong name for the tumor. The spinal cord is the central nervous system that extends from the lower part of the brain to the end of the L1-L2 vertebrae (called the conus medullaris, the lowest part of the spinal cord). L1-L2 is above the coccyx, so spinal cord tumors can only occur from the neck to L2. Below L2, there is no spinal cord, only a cluster of nerves called the cauda equina.
In your case, it is highly likely that the S2 and S1 nerve tumors are in the sacrococcygeal region. These nerves have the function of controlling sensation in the echo area and the sphincter muscles in the perineum. Symptoms related to S1 and S2 neuromas often include numbness, loss of sensation in the echogenic area, uncontrolled walking, urine leakage…
You have a tumor of about 2 cm, so you should go to the doctor to have the appropriate diagnosis done before surgery. Usually, to diagnose a tumor in the sacral region, the doctor uses a 1.5 or 3 Tesla magnetic resonance imaging (MRI) technique. If your previous MRI is still valid, the doctor will use it again. You may also be prescribed a CT scan with contrast to clearly see the lesion in relation to the nerves in this area.
There are cases where neuromas cause lumps and bumps on the surface of the skin and on the limbs. Another special form is tumors that appear on the nerves in the spinal canal. During surgery, the doctor will remove symptomatic tumors. Asymptomatic tumors can be temporarily kept and monitored.
At Tam Anh General Hospital, neuromas, cauda equina or sacral tumors as you described can be operated on using techniques and machines such as the Modus V Synaptive artificial intelligence robot, combined with 3D microsurgery glasses to dissect and remove the entire tumor safely, preserving the nerves in this area.
You can go to the hospital for a doctor to specifically examine and assess the overall appearance of the tumor and its relationship to the nerves. From there, the doctor offers the most suitable treatment plan.
