Haemangioblastoma with multiple dural arterial supply. Case report

Area of Science:

• Neurosurgery
• Neuroradiology
• Vascular Oncology

Background:

• Haemangioblastomas are highly vascular central nervous system tumors.
• Understanding tumor vascularity is critical for surgical planning and management.
• Primary haemangioblastomas can exhibit diverse vascular patterns.

Observation:

• A rare case of primary haemangioblastoma presented with significant vascularity.
• The tumor received a marked blood supply from multiple meningeal branches.
• These feeders originated from both internal and external carotid arteries.

Findings:

• Detailed angiographic study revealed unusual and extensive arterial supply to the haemangioblastoma.
• Identification of multiple meningeal feeders highlights the complexity of tumor vascularization.
• The findings underscore the importance of comprehensive vascular assessment.

Implications:

• Detailed pre-operative angiographic evaluation is essential for identifying unusual feeders in haemangioblastomas.
• Precise knowledge of tumor vascular supply aids in minimizing intraoperative hemorrhage.
• This case emphasizes the clinical significance of meticulous radiological assessment in neuro-oncology.
