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.
Prolactinoma is most frequently a sporadic tumor, occurring in people without any concrete risk factors or family members with similar conditions. [2] [6] In a minority of cases, genetics predispose the patient to having one or more pituitary gland tumors during their lifetime. Most cases of prolactinoma have no known causes or risk factors.

The human pineal gland grows in size until about 1–2 years of age, remaining stable thereafter, [20] [21] although its weight increases gradually from puberty onwards. [ 22 ] [ 23 ] The abundant melatonin levels in children are believed to inhibit sexual development, and pineal tumors have been linked with precocious puberty .
Alzheimer's disease is the most common form of dementia, affecting more than three million Americans per year. And while its exact cause is unknown, researchers may have just had a breakthrough.
They normally take over the neuraxis, the axis of the central nervous system that determines how the nervous system is placed, which allows the cysts to infiltrate the CNS tissues. [3] They are most commonly found in the area near the pineal gland , the chiasmatic cistern , and the cerebellopontine angle space.

Factors other than obesity, however, perhaps genetic and/or environmental ones, are needed to explain the higher prevalence of early puberty in black versus white girls." [ 18 ] While more girls are increasingly entering puberty at younger ages, new research indicates that some boys are actually starting later ( delayed puberty ).
