Tuberculum Sellae Meningiomas: Transcranial Approaches Results and Complications

Abstract

Objective: Tuberculum sellae meningiomas constitute about 5% - 10% of intracranial meningiomas. They are difficult to treat, owing to their close association with the optic nerves, chiasma, and major cerebral arteries. This retrospective study aims to report on the clinical outcome after transcranial approach for treatment of tuberculem sellae meningiomas at our hospital. Patients and Methods: We reviewed patients with tuberculem sellae meningiomas and underwent transcranial surgical approaches for their lesions at Sohag university hospitals over a 4 years period starting from January 2018. The patients’ clinical and radiological data, operative details, degrees of tumor removal, outcomes and complications were reported. Results: There were 17 patients with tuberculem sellae meningiomas with a mean age of 46.3 years. Female patients constituted 70% of cases. Pterional approach was used in 59% of cases and unilateral subfrontal approach was used in 41% of cases. Gross total tumor removal was achieved in 82% of cases. Visual acuity improved in 47%, remained unchanged in 41%, and worsened in 5.9% of patients. Transient post-operative diabetes inspidus and post-operative haematoma in tumor bed each occurred in 5.9% of patients. Conclusion: Transcranial removal of tuberculum sellae meningioma is still considered the standard approach, with high rate of gross total resection and better visual outcome and low mortality and morbidity.
