	Diagnosis	Colloid Cyst
	History	38 year old man with incidental finding on previous head CT.
	Findings	There is a hyperintense spherical lesion at the superior aspect of the third ventricle on the FLAIR and T1 sequences, measuring approximately 5 mm in diameter. There is no enlargement of the ventricular system, suggesting that this lesion does not obstruct CSF flow through the third ventricle.
	Differential Dx	Differential diagnosis includes: -Colloid cyst -Meningioma -Elongated Basilar Artery

	Diagnosis	Colloid cyst of the third ventricle
	History	27yo white man presents to the emergency room with acute onset of headache.
	Findings	Noncontrast CT of the head demonstrates a well-circumscribed hyperdense mass in the anterior portion of third ventricle in the region of foramen of Monroe. There is asymmetric enlargement of the right ventricle suggestive of hydrocephalus. MR images demonstrate a well-circumscribed mass in the anterior portion of the third ventricle at the foramen of Monroe that is hyperintense on T1, mildly hyperintense on T2 and demonstrates some peripheral rim enhancement on post contrast images.
	Differential Dx	Colloid Cyst Central Neurocytoma Gliomas (subependymal giant cell tumor in Tuberous Sclerosis, pilocytic astrocytoma, oligodendrogliomas) Craniopharyngioma Choroid Plexus Papilloma Vascular Tumors Cysticercosis

	Diagnosis	Colloid cyst.
	History	29 year old female with worsening headaches.
	Findings	11 x 11 x 13 mm nonenhancing well-circumscribed mildly T1 hyperintense and markedly T2 hypointense round mass in the anterior-superior third ventricle without ventricular enlargement.
	Differential Dx	Colloid cyst. Although other lesions can occur in this region such as ependymoma, subependymoma, giant cell astrocytoma and central neurocytoma,the imaging findings are characteristic for a colloid cyst.

	Diagnosis	Colloid (neuroepithelial) cyst of the third ventricle.
	History	25 year old with prior bilateral ventricular shunting complained of poor short-term memory (Film .1 and .2).
	Findings	Sagittal noncontrast T1-weighted image (Film 1) reveals a homogeneously hyperintense oval unilocular mass of the anterior superior third ventricle at the foramen of Monro. The ventricles are decompressed, with left frontal and right parietal ventricular shunts in place. The axial T2-weighted image (Film 2) again demonstrates small ventricles after bilateral shunting. The mass is centered at the foramen of Monro and is homogeneous and markedly hypointense to both CSF and brain parenchyma. No other lesions are apparent.
