摘要

Background The differentiation of infratentorial ganglioglioma and pilocytic astrocytoma may be therapeutically relevant, which is sometimes challenging to both pathologists and neuroradiologists. Purpose To evaluate the conventional magnetic resonance imaging (MRI), diffusion-weighted imaging (DWI), and dynamic susceptibility contrast-enhanced perfusion weighted imaging (DSC-PWI) features of infratentorial ganglioglioma compared with pilocytic astrocytoma. Material and Methods This retrospective study enrolled 12 patients with infratentorial ganglioglioma and 61 patients with pilocytic astrocytoma who underwent MRI before surgery. DSC-PWI was performed in 20 patients (4 gangliogliomas, 16 pilocytic astrocytoma). Demographics, conventional imaging characteristics (tumor location, margin, cystic change, enhancement, peritumoral edema, and ipsilateral cerebellar atrophy), rADC(min), and rCBV(max) ratio were compared. The optimum threshold, sensitivity, and specificity for rADC(min) and rCBV(max) ratios were determined. Results Infratentorial ganglioglioma appeared similar to pilocytic astrocytoma but was more likely to have an ill-defined margin (P = 0.035), ipsilateral cerebellar atrophy (P 1.64. Conclusion Conventional MRI, DWI, and DSC-PWI can help to differentiate infratentorial ganglioglioma from pilocytic astrocytoma. DWI offers optimal sensitivity.
