Fig. 4From: Two cases in which 3D MRI was used to differentiate between a disc mass that mimics a tumor and neurinomaPreoperative MRI of the lumbar spine without intravenous contrast and with gadolinium- enhanced MRI. T2-weighted MRI in the sagittal plane was used to aid in localization (a). T2-weighted images in the axial planes revealed a dumbbell mass in the lateral recess (b). Gadolinium-enhanced MRI demonstrated a heterogeneous ring-like enhancement at the periphery of the mass (c)Back to article page
