Summary
A rare case of isolated parenchymal venous varix, undetectable by angiography, was identified. Advanced imaging revealed a unique cystic lesion with specific enhancement patterns and hemosiderin deposits.
Area of Science:
- Neurology
- Neuroradiology
- Vascular Malformations
Background:
- Parenchymal venous varices are rare vascular malformations.
- Diagnosis can be challenging, especially when not visualized with conventional angiography.
Observation:
- A case presented with an isolated parenchymal venous varix.
- The lesion was located deep within the left temporal lobe.
Findings:
- Computed Tomography (CT) revealed a well-defined cystic lesion with peripheral enhancement.
- Magnetic Resonance (MR) imaging demonstrated a high-signal-intensity lesion with a hemosiderin rim, suggesting prior hemorrhage.
Implications:
- This case highlights the utility of advanced neuroimaging techniques in diagnosing rare vascular anomalies.
- Understanding imaging characteristics is crucial for accurate diagnosis and management of parenchymal venous varices.
