Imaging of Neurocysticercosis

Imaging of Parasitic Brain Infections, Part 1: Neurocysticercosis What happens when a tapeworm invades the human brain? In this first episode of a series on imaging of parasitic brain infections, we will talk about the most common parasitic CNS infection worldwide: neurocysticercosis. In this video we discuss: The life cycle of Taenia solium How it ends up in the brain The classic imaging stages (vesicular, colloidal, nodular, calcified) Key tips to distinguish it from tuberculomas a High-yield CT and MRI findings that will stick with you 0:00 - Introduction 0:48 - The Life Cycle of Taenia solium 5:06 - How it ends up in the brain 06:09 - Where is the disease endemic? 06:58 - Symptoms 08:15 - Parenchymal vs. extraparenchymal disease 09:09 - Classical MRI look: the hole-in-dot sign 15:32 - The four stages of parenchymal disease 16:08 - The vesicular stage 17:32 - Colloidal stage 22:07 - Granular-nodular stage 23:51 - Chronic stage 25:25 - Summary of the 4 stages 27:04 - Subarachnoid neurocysticercosis 31:04 - Intraventricular neurocysticercosis 32:09 - DDx: tuberculoma 36:07 - Summary & Key Messages Subscribe for more videos on neuroimaging, including Part 2 coming soon: Cerebral Toxoplasmosis. #radiology #neuroradiology #neurology #neurosurgery #neurosurgeon #medicaleducation #medical #medicalstudent #stroke #neurosurgery #foamed #medical #medicalstudent #neurocysticercosis #parasiticbraindisease #tapeworm #infectiousdisease
