We report a case of a colloid cyst in the foramen of Monro, with an unusual finding of psammomatous calcifications. Colloid cysts of the third ventricle with calcifications in the wall are very rare. Colloid cysts are benign, slowly progressing lesions that most often arise from the roof of the anterior third ventricle along the foramen of Monro, account for almost 0.5-2% of all intracranial neoplasms, ranging from 1 to 3 cm in diameter and contain intraluminal homogenous mucoid or semi-solid colloid like material. Few cases have also been reported in septum pellucidum and fourth ventricle. They are usually incidentally discovered or can cause repeated attacks of worsening headache, syncope, memory loss and visual disturbances.
