The value of small-FOV thin-section MR imaging in the diagnosis of small lesions of the foramen of Monroe is demonstrated. Open surgical resection is the traditional approach to both supra- and infra-tentorial cysts, but location of the cyst and proximity to the ventricles or subarachnoid space are paramount in selection of surgical approach (60).

The most frequent cause is a small focal germinal matrix hemorrhage with subsequent removal of blood leaving a fluid-filled cyst and surrounding gliosis in the subependymal tissue. Cavities within tumors and residual cavities that remain after parenchymal destruction by various agents including infection and circulatory disturbances are often and confusingly called cysts.

These small but macroscopic lesions usually occur in the germinal matrix just beneath the preserved ependyma without rupture into the ventricular lumen. In the first type of choroid plexus cyst, it is not as easily explained why the cyst should enlarge by accumulating more fluid, but the same occurs in many cases or the cyst is more likely to persist into postnatal life beyond the neonatal period.

Other locations described are in the chiasmatic or interpeduncular cisterns (33) or in the perimesencephalic cistern (68). Antenatal choroid plexus cysts are benign and are often transient typically resulting in utero from an infolding of the neuroepithelium. Neither ependymal nor choroid plexus epithelial cells retain a proliferative mitotic potential so that after injury, new epithelial cells only can be generated from pluripotential resident neuroepithelial stem cells in the subventricular zone (64; 62).
