Background and Aim: Cavernous sinus hemangiomas (CSH) are rare benign vascular tumors that can result in headaches, visual disturbances, and cranial nerve palsies due to their location within the cavernous sinus.

Case Presentation: A 56-year-old woman presented with a headache and blurred vision persisting for the last 3 months. There were no previous surgeries, allergies, or known diseases. Upon admission, a neurological examination revealed no cranial nerve involvement, motor or sensory deficits, or other vision disturbances. Cranial magnetic resonance imaging (MRI) was obtained, which showed a 16.1×17.9 mm T2 hyperintense lesion in the cavernous sinus. Endoscopic endonasal transsphenoidal was used for the removal of the tumor. Post-operative MRI revealed total removal of the tumor. Histopathological analysis confirmed the lesion to cavernous sinus hemangioma. There were no complications or recurrences during the 6-month follow-up.

Conclusion: This case demonstrates the successful application of endoscopic endonasal transsphenoidal surgery (EETS) for the complete resection of cavernous sinus hemangioma.
