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.
Cancer in cats is the leading cause of death among cats. It is caused by uncontrolled cell growth, and affects a wide range of cell types and organs in the body. Feline cancer initially manifests as a lump or bump on any part of the body.
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.
I'd like to clarify that a cyst is not a tumor. It is my understanding that a cyst is fluid filled, whereas a tumor is a solid mass. As for the pineal gland cyst, most are asymptomatic - in other words, individuals lead normal lives with none of those symptoms described by in this article. Right now, there are no known causes of pineal gland cysts.
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]
Some cysts in the CNS can be asymptomatic (producing or showing no symptoms), depending on their location in the brain or spinal cord. If the cysts develop in critical areas of the central nervous system, they can present one or more of the following symptoms: [6] Pressure in the spinal cord or brain Rupture of nerves around the cyst
