To review and categorize the various patterns of intracranial enhancement on MRI with illustrative examples. Learn a pattern recognition algorithm to give appropriate differentials. Learn to correlate the imaging features with clinical and histopathological findings.  

Introduction: Appropriate radiological diagnosis of brain lesions can be made with knowledge of location (cortical, grey-white matter, deep white matter, periventricular or ependymal) and pattern of contrast enhancement. Methods: 15 different contrast enhancement patterns of common and rare pathologies are categorized under the following broad headings: meningeal, parenchymal, cranial nerve and vessel wall enhancement. Meningeal includes lepto and pachymeningeal enhancement. Parenchymal includes gyral, nodular, ring, open ring, onion ring ,cyst with mural nodule, diffuse lesional enhancement, satellite lesional enhancement, ependymal enhancement, swiss- cheese, tree-in-bud and folia pattern of enhancement. Cranial nerve and vessel wall enhancement patterns. We present our institution experience of the above mentioned patterns in a case based algorithm with relevant differentials with supporting clinical findings and histological correlation when available.
