This is just one example of how the Greek root cyst-, which simply means a fluid-filled sac, also is found in medical terms that relate to the urinary bladder and the gallbladder , neither of which involve cysts. Cancer-related cysts are formed as a defense mechanism for the body, following the development of mutations that lead to an uncontrolled cellular division.
A cyst is a closed sac, having a distinct membrane and division compared with the nearby tissue Hence, it is a cluster of cells that has grouped together to form a sac (not unlike the manner in which water molecules group together, forming a bubble); however, the distinguishing aspect of a cyst is that the cells forming the “shell” of such a sac are distinctly abnormal (in both appearance and behaviour) when compared with all surrounding cells for that given location. Cysts may be recurring; this may happen in some cysts when only the cyst contents are reduced or removed and the cyst covering or lining remains; others may reoccur due to underlying causes. Some benign but large cysts may have a fair to good prognosis but may require surgery or aspiration to reduce or eliminate symptoms.
The type of doctor that treat cysts depend on the underlying cause of the cyst and the symptoms, if any, that are produced by the cyst. Aneurysmal cyst: These lesions are found in bones and other structures and consist of neoplastic cells and blood vessels that resemble a sponge-like structure; they are neither cysts nor aneurysms, but the term is still used. PCOS ( polycystic ovary syndrome ): enlarged ovaries due to an endocrine problem that contain a number of fluid-filled cysts (follicles)
However, some cysts on the skin, mucous membranes, and those located in palpable organs often can be felt as a lump or bump; sometimes they are painful. While the approach varies depending on the size and location of the arachnoid cyst, fully endoscopic surgical management has provided the surgeon with superior access for either fenestration, or in other cases, resection of the cyst without the complications and risks associated with brain manipulation or retraction. The severity and associated symptoms of porencephaly vary dramatically from one person to another based upon the size and exact locations of the fluid-filled cavities or cysts.
Some complications of arachnoid cysts can occur when a cyst is damaged because of minor head trauma. Although they occur much less often than those found within the skull (intracranial), arachnoid cysts may also arise near the spine (spinal arachnoid cysts). However, cysts can increase in size causing symptoms to appear, especially if they press against a cranial nerve, the brain, or the spinal cord.
In cases in which symptoms occur, headaches, seizures and abnormal accumulation of excessive cerebrospinal fluid in the brain (hydrocephalus) are common. Unlike arachnoid cysts, which usually do not grow in size, colloid cysts are expected to increase in size slowly over time. Like other cysts that occur in the brain, such as arachnoid cysts , colloid cysts are always benign.
