Abstract:
We report MRI findings in four patients with essential primary cutis verticis gyrata (CVG). The patients were all men, aged 49-81 years (mean 65 years). They had no symptoms related to this rare scalp condition, preceding scalp disease or associated systemic disease. Coronal images showed a characteristic corrugated appearance of the thickened scalp at the vertex, diagnostic of CVG. Neuroradiologists should be aware of this condition.

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...
