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.
A pinealoma is a tumor of the pineal gland, a part of the brain that produces melatonin. If a pinealoma destroys the cells of the pineal gland in a child, it can cause precocious puberty . Signs and symptoms
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.
"Central precocious puberty (CPP) was reported in some patients with suprasellar arachnoid cysts (SAC), and SCFE (slipped capital femoral epiphysis) occurs in patients with CPP because of rapid growth and changes of growth hormone secretion." [13] If no cause can be identified, it is considered idiopathic or constitutional.
They are most commonly found in the area near the pineal gland, the chiasmatic cistern, and the cerebellopontine angle space. These common places generally house extensive and continuously growing cysts. [2] Some examples of cysts originating from non-central nervous system tissue include: [citation needed]
The pineal gland (also known as the pineal body [1] or epiphysis cerebri) is a small endocrine gland in the brain of most vertebrates. It produces melatonin , a serotonin -derived hormone , which modulates sleep patterns following the diurnal cycles . [ 2 ]
