Imaging mimics are not uncommon in pediatric neuroradiology. Accurate diagnosis guides optimal management.  This exhibit: 1) Familiarizes the radiologist with similar appearing pediatric neuroradiological entities in order to broaden differential diagnosis, improve diagnostic accuracy, and guide optimal management 2) Teaches the radiologist to select additional imaging tests that clarify diagnosis. 3) Discusses clinical features, multimodality imaging signs, and therapeutic considerations in several challenging cases of easily mistaken entities in pediatric neuroradiology.  

Cases will be presented in quiz format. Key differential diagnostic, clinical and imaging semiology, and management considerations will be discussed each case. Case selection with mimicked entity in parentheses: Intracranial aneurysm (tumor) CNS vasculitis (tumor) Vein of Galen malformation (pineal cyst) Spinal cord infarction (tumor) Tumefactive demyelination (tumor, tumoral edema) Giant tumefactive perivascular spaces (vascular lesion) Cavernoma (glioma) Callosal lipoma (ruptured dermoid) Cerebritis (glioma) Limbic encephalitis (glioma) Sphenoid bone fibrous dysplasia (sarcoma) Pyogenic abscess (centrally necrotic tumor) Racemose neurocysticercosis (ependymal cyst) Hirayama disease (epidural mass/abscess)
