Contrast-enhanced MRI significantly improves the detection of small venous angiomas (VA), revealing a 12% incidence of double VA in patients receiving contrast medium. This highlights the importance of contrast for comprehensive venous malformation diagnosis.

Area of Science:

  • Neuroradiology
  • Vascular Neurology
  • Medical Imaging

Background:

  • Venous angiomas (VA) are congenital vascular malformations.
  • Accurate detection of all venous angiomas is crucial for patient management.
  • Standard imaging may miss small or subtle lesions.

Purpose of the Study:

  • To evaluate the efficacy of contrast-enhanced magnetic resonance imaging (MRI) in detecting venous angiomas.
  • To determine the incidence of multiple venous angiomas in a patient cohort.
  • To assess the diagnostic yield of contrast medium in identifying small venous angiomas.

Main Methods:

  • A cohort of 58 patients with venous angiomas underwent 1.5 Tesla MRI.
  • 33 patients received contrast medium during MRI.

  • 29 patients underwent selective cerebral angiography for comparison.

    • Main Results:

    • A total of 63 venous angiomas were identified across 58 patients.
    • Five patients (8.6%) had two venous angiomas.
    • Contrast-enhanced MRI detected small venous angiomas missed on non-enhanced images, revealing a 12% incidence (4/33) of double venous angiomas in contrast-enhanced studies.

    Conclusions:

    • Contrast-enhanced MRI is superior to non-enhanced imaging for detecting small venous angiomas.
    • Intravenous contrast medium increases the diagnostic sensitivity for identifying multiple venous angiomas.
    • Routine use of contrast medium in MRI protocols for venous angiomas is recommended for comprehensive evaluation.
