title: Giant extradural sacral meningioma.
abstract: We present the first case of primary benign fibrous meningioma restricted to the sacrum with no sign of recurrence after a long follow-up duration. This occurred in a 36-year-old man who initially presented with a 3-month history of right-sided sciatica. The tumour was successfully resected after three surgical procedures due to its high vascularity and technical difficulties. Sacroiliac joint stability was not disrupted, and he is still doing well clinically at 8 years follow-up.
