A study found 18% of patients with intracranial arachnoid cysts had non-specific headaches. The cyst was in the temporal location in 75% of these cases. [7] Seizures [2] Hydrocephalus (excessive accumulation of cerebrospinal fluid) [2] Increased intracranial pressure [2] Developmental delay [2] Behavioral changes [2] Nausea; Dysdiadokinesis
The chances of intracranial epidermoids is about 1% of all brain tumors. This benign tumor of the brain is made up of normal skin cells (stratified epithelial lining) on the outside, and fatty acids and keratin are on the inside of the tumor or sac. Only the sticky outer membrane is alive thus sticking to brain tissues and nerves.
These classification of cysts are embedded in the endoderm (inner layer) and the ectoderm (outer layer) of the cranial or spinal cord germ layers.They normally take over the neuraxis, the axis of the central nervous system that determines how the nervous system is placed, which allows the cysts to infiltrate the CNS tissues.

The presence of porencephalic cysts or cavities can be detected using trans-illumination of the skull of infant patients. Porencephaly is usually diagnosed clinically using the patients and families history, clinical observations, or based on the presence of certain characteristic neurological and physiological features of porencephaly.
Nasopharyngeal cyst refers to cystic swelling arising from midline and lateral wall of the nasopharynx. The commonest cyst arising from lateral wall is the nasopharyngeal branchial cyst, whereas the mucus retention cysts are the commonest to arise from the midline. [1] Sometimes nasopharyngeal cyst may directly refer to Tornwaldt cyst. [2]
A woman’s skull was discovered inside the walls of a suburban Illinois home back in 1978, and now—almost 50 years later—we finally know her name. Esther Granger was identified by the Kane ...
There are four types of ovarian cysts — functional cysts, PCOS cysts, benign ovarian tumor and malignant ovarian tumor — that range from harmless to fatal.
CT scan of a 1 cm colloid cyst. A colloid cyst is a non-malignant tumor in the brain. It consists of a gelatinous material contained within a membrane of epithelial tissue. It is almost always found just posterior to the foramen of Monro in the anterior aspect of the third ventricle, originating from the roof of the ventricle.
