BACKGROUND: Spheno-orbital meningioma (SOM) represents a unique variant of sphenoid wing meningiomas, distinguished by its propensity for bone infiltration and cranio-orbital involvement. SOM exhibits a considerable incidence of misdiagnosis and recurrence.
PURPOSES: To elucidate the clinical, radiological, and pathological characteristics of SOM.
METHODS: Review of electronic medical records, histopathology, radiological images and follow-up information of 100 SOM patients.
RESULTS: Of the 100 patients (28 males, 72 females) with SOM, mean age was 46.8 ± 12.6 years and prevalent symptoms were proptosis (99%). All the CT scans showed hyperostosis with 89.3% of the hyperostosis having an irregular edge. In MRI scans, dural tail sign was observed across all patients and the cranio-orbital tumors often penetrated temporal muscle (74.1%), extraocular muscle (74.1%) and lacrimal gland (63%). All the 100 patients underwent surgical intervention, and among them, 62 individuals received postoperative radiotherapy. Grade I resections had a lower recurrence rate(16.7%), which further decreased with the addition of radiotherapy(13.9%). In contrast, all patients with grade II or higher grade resections without radiotherapy experienced recurrence, indicating a higher risk associated with less complete tumor removal. The pathological examination revealed that intraorbital sections exhibited comparable tumor density to intraorbital SOM tumors, along with increased fibrous density but decreased vascular distribution.
CONCLUSIONS: Radiological characteristics of SOM included cranio-orbital tumors, hyperostosis of the sphenoid wing with an irregular edge, and dural tail sign. Combination of gross total resection and adjuvant radiotherapy was recommended to minimize recurrence rate. Intracranial SOM tumors tended to be softer and more bleed-prone than intraorbital sections, necessitating surgical precision.
