Tumefactive perivascular spaces, enlarged fluid-filled spaces around brain arteries, can mimic tumors. This study highlights advanced MR imaging findings of these unusual spaces, including visualization of the perforating artery.
Area of Science:
- Neuroimaging
- Radiology
- Cerebrovascular Anatomy
Background:
- Cerebral perivascular spaces are interstitial fluid-filled structures surrounding perforating arteries.
- These spaces typically appear as small, round, or curvilinear structures on magnetic resonance (MR) imaging.
- Enlarged perivascular spaces, termed tumefactive perivascular spaces, can cause mass effect and mimic malignant conditions.

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...
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...
