Presentation
Headaches.
Patient Data
Small nodules in the right lateral ventricle frontal horn. With a target appearance. No convincing contrast enhancement or diffusion restriction. These nodules are intermediate intensity on T1 and T2-weighted imaging. Otherwise, no intracranial mass, hemorrhage or collection. The ventricles and sulci are age-appropriate. No regions of abnormal parenchymal signal, contrast enhancement or diffusion restriction.
Case Discussion
No cause for the patient's presentation. Small right lateral ventricle frontal horn nodules are entirely consistent with ring-shaped lateral ventricular nodules (RSLVN), which may or may not be a subset of subependymomas (which would otherwise be the differential). Either way, they are considered entirely incidental.
