Colloid Cyst-MRI

The term colloid cyst refers to only neuroepithelial cysts that arise in the anterosuperior third ventricle, near the foramina of Monro. The cysts are lined by a single layer of epithelial cells and are typically filled with a thick, viscous mucus that has an array of ingredients, including blood products, macrophages, cholesterol crystals, and numerous metallic ions, such as copper, iron, magnesium, aluminum, and phosphorus. This is a 18 year old female who presented with complaints of headache. Note the cyst is hyperintense on T1 weighted image.
