A pinealoma may cause interruption of hypothalamic inhibiting pathways, sometimes leading to beta-hCG secretion and consequent Leydig's cell stimulation (endocrine syndrome). [citation needed] Other symptoms may include hydrocephalus, gait disturbances, and precocious puberty. [citation needed]
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.
MRI of a patient with anaplastic astrocytoma. The WHO classification of tumours of the central nervous system is a World Health Organization Blue Book that defines, describes and classifies tumours of the central nervous system (CNS).
A nervous system tumor is a tumor that arises within the nervous system, either the central nervous system (CNS) or the peripheral nervous system (PNS). [1] [2] Nervous system primary tumors include various types of brain tumor and spinal tumors, such as gliomas, and meningiomas (of the CNS), and schwannomas (of the PNS) and can be either benign or malignant.
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.
An endocrine gland neoplasm is a neoplasm affecting one or more glands of the endocrine system. [citation needed] Examples include: Adrenal tumor; Pituitary adenoma; The most common form is thyroid cancer. [1]
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]
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]
