Images caption: (a) Transverse graphic representation shows multiple cystic masses in the choroid plexus glomi (arrows). Most CPCs are actually degenerative xanthogranulomas.

CHOROID PLEXUS CYSTS
Choroid plexus cysts (CPCs) are nonneoplastic epithelial-lined cysts of the choroid plexus. They are the most common of all intracranial neuroepithelial cysts, occurring in up to 50% of autopsy cases. Most are bilateral and located in the lateral ventricular atria. The third ventricle is a rare but reported location (1). Most CPCs are asymptomatic and are found incidentally, typically in neonates and older adults. Symptomatic lesions are rare since the atria typically enlarge to accommodate the cyst

The four lobes of the cerebral cortex 1. Frontal lobe - conscious thought; damage can result in mood changes; 2. Parietal lobe - plays important roles in integrating sensory information from various senses, and in the manipulation of objects; portions of the parietal lobe are involved in visuospatial processing. 3. Occipital lobe - sense of sight; lesions can produce hallucinations. 4. Temporal lobe - senses of smell and sound, as well as processing of complex stimuli like faces and scenes. Further: The insula is a portion of cortex in between and covered by the temporal and parietal lobes. Some consider it as a separate lobe, but others as a part of the limbic structure deep in the brain.
