1. Rare but a well-documented side effect of pineal tumors: Occurs in tumors of various histological subtypes as well as in non-neoplastic masses. Bleeding may cause pineal apoplexy or subarachnoid hemorrhage. Massive hemorrhage into choriocarcinomas and endodermal sinus tumors is most frequent. Tumors of the pineal parenchyma are also very vascular.

2. The papillary tumor of the pineal region (PTPR) is a distinct entity that is particularly rare in the pediatric population. The authors document the youngest reported patient with this clinicopathological entity to date. A case of PTPR in a month-old boy is described.

3. 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 this region.

4. Treatment of tumors in the pineal region remains one of the great intellectual and technical challenges to neurological surgeons. The mystique of the even nowadays poorly understood function of the pineal gland, the everlasting beauty of its anatomy, and the unbeatable elegance of the surgical approaches to this region have fascinated generations of neurosurgeons.

5. Management of Hydrocephalus. Most patients present with obstructive hydrocephalus, a problem that may be managed in several ways. 14 When a complete tumor removal is anticipated and a permanent shunt may not be necessary, the hydrocephalus can be managed with a ventricular drain placed at the time of tumor surgery. The ventricular drain can be.

6. pineal region tumors The pineal gland develops during the second month of gestation as a diverticulum in the diencephalic roof of the third ventricle. It is flanked by the posterior and habenular commissures in the rostral portion of the midbrain directly below the splenium of the corpus callosum.

7. Pineal tumors develop in the region of the pineal gland, midline structure located deep in the midbrain area, near many vital structures. Pineal tumors comprise about 1% of all brain tumors but account for 3% to 8% of the intracranial tumors in children. The three most common types of pineal region tumors are gliomas, germ cell tumors, and pineal cell tumors.

8. 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.

9. Pathophysiology Normal Anatomy. The pineal gland is a small reddish-brown structure that derives its name from its pinecone-like shape. The pineal ranges in size from 10 to 14 mm; it is located in the midline, above the tentorium and superior colliculi and below the splenium of the corpus callosum and the vein of Galen, and is attached to the superior aspect of the posterior border of the.
