Two cavernous hemangiomas masquerading as single space occupying tumors in the orbital apex were removed under nasal endoscope: A case report

Introduction and importance: This report details the unusual presentation of two hidden cavernous hemangiomas in the orbital apex, initially appearing as one tumor. The rarity and diagnostic complexity of this case underscore the need for meticulous surgical exploration and verification in orbital apex tumors. Case presentation: A physical examination of an elderly male with a three-year history of headaches revealed a space-occupying lesion in the left orbital apex. Imaging confirmed a tumor in the extraconical space above the optic nerve. Initial nasal endoscopy removed an orbital apex tumor, pathologically confirmed as a cavernous hemangioma. Clinical discussion: Postoperative examination revealed incomplete tumor removal, prompting a second surgery for full excision. This case underscores the diagnostic and management challenges of orbital apex tumors, especially when imaging indicates a single mass. The endoscopic transsphenoidal approach for cavernous hemangiomas in the medial orbital apex, as illustrated in this case, appears promising. Conclusion: Clinicians must be aware of the potential for multiple tumors in orbital apex cases, even if imaging does not explicitly reveal them. This case highlights the importance of thorough surgical exploration and illustrates the effectiveness of endoscopic methods in intricate orbital apex surgeries.
