In the case of choroid plexus papilloma, surgical removal of the cyst-containing lesion from within the third ventricle caused a full recovery. The mobile nature of the cystic lesion led to its intermittent obstruction of the foramen of Monro and proximal aqueduct, producing the bobble-head symptoms. Once removed, all symptoms disappeared.

This type of shunt, called a ventriculoperitoneal shunt, is particularly useful in cases involving hydrocephalus. By continually draining the syrinx, a shunt can arrest the progression of symptoms and relieve pain, headache, and tightness. [27] Many factors affect the decision to use a shunt.
The shunt also has a valve which serves to maintain one-way flow of the CSF and regulates the flow rate. The end with the catheter is placed in the third ventricle to drain the excess CSF and the other end is placed in the peritoneal cavity or atrium of the heart (making it a ventriculoperitoneal or ventriculoatrial shunt, respectively). The ...
The condition usually occurs several years after shunt implantation. The most common symptoms are similar to normal shunt malfunction, but there are several key differences. First, the symptoms are often cyclical and will appear and then subside several times over a lifetime. Second, the symptoms can be alleviated by lying prone.
The symptoms of shunt failure are non-specific – headache, nausea, lethargy – so diagnostic tests must be conducted to rule in or rule out surgery. Current methods of diagnosing shunt malfunction, including CT Scan, MRI, radionuclide studies and shunt tap, have limitations and risks.
For suspected cases of NPH, CSF shunting is the first-line treatment. The most common type used to treat NPH is ventriculoperitoneal (VP) shunts, which drain CSF fluid to the peritoneal cavity. Adjustable valves allow fine-tuning of CSF drainage. NPH symptoms reportedly improve in 70–90% of patients with CSF shunt.

Other symptoms include headaches, the inability to feel changes in the temperature, sweating, sexual dysfunction, and loss of bowel and bladder control. It is usually seen in the cervical region but can extend into the medulla oblongata and pons or it can reach downward into the thoracic or lumbar segments.
