Summary
This case study presents a rare giant cavernous hemangioma in the cavernous sinus, diagnosed using magnetic resonance imaging (MRI). The benign neoplasm involved major arteries, highlighting the importance of advanced imaging for vascular malformations.
Area of Science:
- Neurology
- Radiology
- Pathology
Background:
- Intracranial cavernous hemangiomas are rare vascular malformations, accounting for 0.1-4% of such conditions.
- Giant cavernous hemangiomas in the cavernous sinus are exceptionally uncommon, posing diagnostic and therapeutic challenges.
Purpose of the Study:
- To present a case of a giant cavernous hemangioma in the cavernous sinus.
- To detail the neuroimaging and pathological findings.
- To conduct a literature review on cavernous sinus hemangiomas.
Main Methods:
- Literature search using keywords "hemangioma" and "cavernous sinus" in PubMed and Scielo databases.
- Magnetic resonance imaging (MRI) including FLAIR, T1, and contrast-enhanced T1-weighted sequences.
- Pathological analysis of the resected tumor.
Main Results:
- A giant cavernous hemangioma was identified in the cavernous sinus of a 72-year-old patient.
- Neuroimaging revealed a benign neoplasm involving the left internal carotid artery and contacting the contralateral internal carotid artery.
- Pathological analysis confirmed abundant vascular structures without a muscular tunic.
Conclusions:
- Giant cavernous hemangiomas in the cavernous sinus require advanced imaging techniques like MRI for diagnosis.
- Surgical intervention, potentially combined with radiotherapy or radiosurgery, is the primary treatment modality.
- Understanding the vascular anatomy and characteristics is crucial for surgical planning.
