"no central enhancement, may have thin peripheral rim of enhancement which represents the cyst capsule7"
"T1: variable"
"T1 C+ (Gd): only rarely demonstrates thin rim enhancement, but usually this represents an enhancement of the adjacent and stretched septal veins 3"
"T2: variable"
"FLAIR: cysts which are of low signal on T2 will appear similar to attenuated CSF on FLAIR, and are thus difficult to appreciate 4"
"For a more complete list please refer to masses in the region of the foramen of Monro."
"colloid cysts are most easily seen on CT."
"MRI signal is variable, and it is difficult to predict which sequence will best demonstrate the cyst."
"beware of low T2 signal cysts (most common) as they will appear like CSF on FLAIR and be difficult to see - thus it is essential to have a standard T2 sequence in your protocol."
"Colloid Cyst Risk Score (CCRS) was proposed (c.2016) as a prognostic predictor of the risks associated with this lesion such as obstructive hydrocephalus 6."
"Colloid Cyst Risk Score (CCRS) was proposed (c.2016) as a prognostic predictor of the risks associated with this lesion such as obstructive hydrocephalus 6."
"There are usually no differential diagnoses for a colloid cyst. In atypical cases, it is worth considering other masses which arise in the region of the foramen of Monro, including:"
