Abstract:
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.

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
