A pineal gland cyst is a usually benign (non-malignant) cyst in the pineal gland, a small endocrine gland in the brain. Historically, these fluid-filled bodies appeared on 1-4% of magnetic resonance imaging (MRI) brain scans, but were more frequently diagnosed at death, seen in 4-11% of autopsies. [1]
Pineocytoma, is a rare, benign, slowly growing tumor of the pineal gland. The pineal gland is a small endocrine gland close to the center of the brain that secretes melatonin into the bloodstream. Pineocytomas can cause pressure and fluid build-up in the brain. They are more common in adults.
Treatment: Surgical resection, radiation therapy: A pinealoma is a tumor of the pineal gland, a part of the brain that produces melatonin.
The pineal gland is a small organ in the center of the brain that is responsible for controlling melatonin secretion. [2] Several tumors can occur in the area of the pineal gland, with the most aggressive being pineoblastoma. Pineoblastomas arise from embryonal cells in the pineal gland and are rapidly growing.
Papillary Tumors of the Pineal Region are located on the pineal gland which is located in the center of the brain. The pineal gland is located on roof of the diencephalon. It is a cone-shaped structure dorsal to the midbrain tectum. [3] The tumor appears to be derived from the specialized ependymal cells of the subcommissural organ.
The pineal gland is present in almost all vertebrates, but is absent in protochordates in which there is a simple pineal homologue. The hagfish , archaic vertebrates, lack a pineal gland. [ 7 ] In some species of amphibians and reptiles, the gland is linked to a light-sensing organ, variously called the parietal eye , the pineal eye or the ...
Pinealectomy is a surgical procedure in which the pineal gland is removed. It is performed only in rare cases, where a pineocytoma or a pineal gland cyst has become life-threatening. [citation needed]
These examinations are useful to get a general idea of possible treatment options, but can be unsatisfactory to diagnose CNS cysts. [3] [5] Professionals still do not fully understand how cysts form; however, analyzing the walls of different cyst types, using electron microscopes and light microscopes, has proven to be the best diagnostic tool ...
