Readers will know the differentials of various benign primary CNS neoplasms demonstrating restricted diffusion on MRI. Readers will better appreciate the correlation between diffusion characteristics and histopathological features.  

Introduction: Tumours which demonstrate restricted diffusion are commonly thought of as high grade CNS neoplasms. This is presumed due to increased cellularity and high nuclear-cytoplasmic ratio. We present a pictorial exhibit of benign CNS neoplasms showing restricted diffusion. Methods: The following pathologies will be demonstrated in case-wise manner with clinical, MR imaging and histopathological description. Diffusion MRI  feaures will be correlated with histopathological parameters like cellularity, tumor cell morphology, nuclear-cytoplasmic ratio and extra-cellular matrix. • Meningiomas • Pituitary adenoma • Central neurocytoma • Desmoplastic infantile ganglioglioma • Gangliocytoma • Pilomyxoid astrocytoma • Pleomorphic xanthoastrocytoma • Pineocytoma
