Ring-shaped lateral ventricular nodules (RSLVN) are small and round nodules attached on the ependyma of lateral ventricles with unknown nature. They are considered "leave me alone lesions" and differential diagnosis includes subependymal grey matter heterotopia, subependymomas, subependymal hamartomas, and subependymal giant cell astrocytomas. In this short article, we report imaging findings of RSLNVs discovered in five patients, underlining the pivotal role of neuroimaging in the diagnostic path.
