A pancreatic cyst is a fluid filled sac within the pancreas. The prevalence of pancreatic cysts is 2-15% based on imaging studies, but the prevalence may be as high as 50% based on autopsy series. [1] Most pancreatic cysts are benign and the risk of malignancy (pancreatic cancer) is 0.5-1.5%.
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 ]
Spermatocele is a fluid-filled cyst that develops in the epididymis. [3] The fluid is usually a clear or milky white color and may contain sperm. [4] Spermatoceles are typically filled with spermatozoa [5] and they can vary in size from several millimeters to many centimeters.

Large cysts that cause problems occur in about 8% of women before menopause. [1] Ovarian cysts are present in about 16% of women after menopause, and have a higher risk of being cancer than in younger women. [1] [4] If a cyst appears benign during diagnosis, then it has a less than 1% chance of being either cancer or borderline malignant. [11]
The cysts may be found anterior to the sacral area and have been known to extend into the abdominal cavity. These cysts, though rare, can be found to grow large - over 3–4 centimetres (1.2–1.6 in) in size, often causing severe abdominal pain from compression on the cyst itself as well as adjoining nerves.

Benign cyst kidney; radiological appearances mimic renal cancer, A cyst / s ɪ s t / is a closed sac, having a distinct envelope and division compared with the nearby tissue.Hence, it is a cluster of cells that have grouped together to form a sac (like the manner in which water molecules group together to form a bubble); however, the distinguishing aspect of a cyst is that the cells forming ...
Nabothian cysts usually require no treatment and frequently resolve on their own. [4] Cryotherapy has been used to treat nabothian cysts but is rarely necessary. [4] Very rarely a cyst may be so large that it prevents a clinician from performing a pap smear, in which case the clinician may puncture the cyst with a needle and drain it. [4]
