    Extra-axial skull base cavernous hemangiomas can mimic meningiomas but are distinct entities. Surgical resection is the primary treatment, with embolization and radiotherapy as adjuncts.

    Area of Science:

    • Neurosurgery
    • Neuroradiology
    • Skull Base Surgery

    Background:

    • Extra-axial cavernous hemangiomas (EACs) are rare vascular malformations.
    • They can present with symptoms like headache and oculovisual disturbances.
    • Distinguishing EACs from other skull base tumors is crucial for appropriate management.

    Observation:

    • Two patients with EACs presented with headache and oculovisual issues.
    • Imaging (CT, MRI) suggested basal meningioma, but MRI spectroscopy provided different insights.
    • Lesions were extradural and highly vascular, requiring significant intraoperative management.

    Findings:

    • EACs exhibit distinct clinical and radiological features compared to intraparenchymal cavernous malformations.
    • Magnetic resonance spectroscopy can aid in differential diagnosis.

  • Surgical resection via pterional craniotomy is the treatment of choice.

    • Implications:

    • Preoperative embolization can reduce intraoperative bleeding during surgical resection.
    • Fractionated radiotherapy is a viable alternative for difficult resections or high-risk patients.
    • Understanding EACs' unique characteristics improves diagnostic accuracy and treatment planning.
