ABSTRACT
We present a case of a 37-year-old female, with progressive left eye proptosis and an extensive ipsilateral en plaque spheno-orbital meningioma, with diffuse involvement of the lateral wall of the cavernous sinus and the orbit. A cranio-orbital zygomatic approach was performed to reach all extension of the lesion. We made an extradural clinoidectomy and an extensive bone removal of the orbit, exposition of the superior and lateral walls of the cavernous sinus, unroofing of the optic canal, superior orbital fissure, foramen rotundum, and foramen ovale. We performed the peeling of the lateral wall of cavernous sinus with total removal and preservation of the cranial nerves anatomy and function. In this video, we illustrate the importance of the first time aggressive removal of such tumors. We also demonstrate the concept that secondary invasion of the cavernous sinus are suitable for removal with cranial nerve preservation.

ABSTRACT
BACKGROUND: Sphenoid wing meningiomas with cavernous sinus invasion (SWMCSI) are challenging tumors. The preservation of quality of life and cranial nerve function is one of the most relevant aspects of treating patients with SWMCSI. METHODS: A retrospective study was conducted for surgery performed between 2008 and 2021, including 36 patients presenting with SWMCSI. The data from surgical intervention, Simpson grade of resection, tumor location, and morbimortality related to the surgery was reviewed. We examined the medical records, operative reports, radiologic examinations, and follow-up information. RESULTS: The group comprised 29 women and 7 men with an average age of 61 years (range, 31-87 years). The mean follow-up period was 75 months (range, 1-170 months). Simpson grade I and II resections were obtained in 80% of cases. The meningiomas were World Health Organization (WHO) grade 1 in 94% of cases, WHO grade 2 in 3%, and WHO grade 3 in 3%. The overall mortality was 5.5%. Permanent cranial nerve deficits occurred in 8% of cases, transient cranial nerve deficits in 22%, cerebrospinal fistula in 16.5%, and hemiparesis in 2.7%. The recurrence/regrowth rate was 14% during the follow-up period. The Karnofsky Performance Status 100 and 90 was 92%. CONCLUSIONS: The surgical treatment of symptomatic SWMCSI is an effective treatment modality with low morbimortality and good long-term control of the disease. Visual impairment is the most common abnormality, affecting preoperative and postoperative quality of life of patients with SWMCSI. Training in the microsurgical laboratory is essential for safe surgical approaches in this area.

The present case reports a 13-year-old patient with an intradural arachnoid cyst, which manifested itself with a sudden loss of strength and sensitivity in the lower and upper limbs and a severe pain in the cervical and thoracic region. On examination, a lesion displayed as an intradural hematoma; however, a laminotomy was performed and it was realized that the lesion was an arachnoid spinal cyst of the cervical-dorsal spine.
