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.
