  1. As with many other brain tumors, pineal region tumors are best treated with surgery. The surgery, called resection, removes all or part of the tumor — the more tumor that’s removed the better the prognosis for recovery. These surgical procedures are highly involved and can take several hours.
  2. Background: Papillary tumor of the pineal region (PTPR) is a rare neoplasm with only anecdotal data to guide the treatment. Results of treatment with surgery, radiation therapy, and chemotherapy.
  3. Dec 03,  · Pineal region tumors are rare tumors, with an estimated overall incidence of about 1% of all intracranial tumors (ranging from % to % in different studies) and are more common in children (%) than in adults (less than 1%). Also, the incidence of pineal region tumors is higher among the Japanese, at % of all intracranial tumors.
  4. Pineoblastoma is more aggressive than other types of pineal gland tumors. Its fast growth usually causes cerebrospinal fluid (CSF) to build up in the brain. This condition is called hydrocephalus. While pineoblastoma may spread through the CSF in 10% to 20% of cases, most of the time the tumors do not spread to other parts of the body.
  5. Pathophysiology Normal pineal gland: The pineal gland is composed of pineocytes (95%) and supporting glial cells (5%) (22, 34). Pineocytes are the principal parenchymal neurons of the pineal gland and function as neuroendocrine transducers. Pineocytes release melatonin and serotonin in response to light signaling detected by retinal ganglion cells and transmitted through the suprachiasmatic.
  6. Pineal tumors arise in the region of the pineal gland. This gland is a small structure deep within the brain. These tumors represent about 1% of all brain tumors but account for 3% to 8% of the intracranial tumors that occur in children. At least 17 different types of tumors may occur in .
  7. Serum and CSF markers contribute to the diagnosis of pineal parenchymal tumors. b-HCG is mainly positive in choriocarcinomas, embryonal carcinomas and mixed germ cell tumors and AFP is .
  8. Nov 28,  · Pineal gland tumors 1. Pineal Gland Tumors 2. Introduction Pineal Gland is midline structure located in the epithalamus, near the centre of the brain, between the two hemispheres, in a groove where the two halves of the thalamus join. Pineal region neoplasm's constitute only % of intracranial tumors.
  9. The role of surgery in the management of pineal region tumors is influenced by the histological diagnosis and tumor growth characteristics. Tumors of the pineal region typically present with obstructive hydrocephalus from occlusion of the aqueduct, which often requires CSF diversion as an initial management pingbeetvantgistvisanrerolabdiopase.coinfo by: 3.
