Thoracic (mid-dorsal) intradural extramedullary tumors that enhance homogeneously on contrast MRI and cause slowly progressive spastic paraparesis are classically spinal meningiomas; they occur predominantly in middle-aged women and account for the majority of such lesions, whereas lipomas and dermoid/epidermoid cysts show fat signal or minimal enhancement.
