Аннотация
INTRODUCTION: Purely temporal intraventricular tumors are uncommon. Given their deep location, access to these brain tumors can be challenging in terms of preserving brain tissue. The subtemporal approach spares the lateral temporal cortex and is a less traumatic corridor to reach intraventricular temporal tumors.
OBJECTIVE: To describe and assess the feasibility of the subtemporal transcollateral approach for the removal of a temporal horn tumor.
METHODS: We describe the subtemporal transcollateral sulcus operative technique detailed step-by-step and depicted through both video and illustrations to surgically resect a left intraventricular temporal mass in a 44-year-old woman who presented with worsening memory deficits. The surgery was performed under general anesthesia and with the use of a microscope and neuronavigation.
RESULTS: The patient did not suffer from any postoperative complications. Her vision was intact, and her memory deficit was unchanged. A brain MRI showed complete removal of the tumor. The pathological examination revealed a World Health Organization grade I meningioma.
CONCLUSION: The subtemporal transsulcal approach seems to be an efficient and safe way to access intraventricular lesions within the temporal horn while avoiding any disruption of the optic radiations and temporal language areas.
