Garima Agrawal MD, Presenter: Nothing to Disclose

Hilary L. Purdy MD, Abstract Co-Author: Nothing to Disclose

Aseem Sharma MBBS, Abstract Co-Author: Stockholder, General Electric Company

The goal of the exhibit is to: 1. Understand the normal physiology of CSF production, absorption and flow dynamics. 2. Discuss pathophysiology of altered CSF dynamics in various pathologies 3. Understand imaging characteristics that aid in diagnosis and management of various pathologies of altered CSF dynamics.    

1. Csf production: Normal physiology and case based discussion of CSF over production 2. Csf absorption: Normal physiology, understand Benign extraaxial fluid collection of infancy and case based discussion of dysfunction of absorptive mechanism in processes such as meningitis, subarachnoid hemorrhage, leptomeningeal carcinomatosis and venous hypertension. 3. CSF flow: Physiology, Munro Kelly doctrine, Imaging of flow and case based discussion of pathologies that will include obstructive hydrocephalus which could be intraventricular, fourth ventricular outlet, craniospinal junction (Chiari I and others) or intraspinal obstruction (arachnoid adhesions etc). 4. CSF leaks and hypovolemia: Case based discussion of various causes of CSF leaks and spectrum of imaging findings that lead to establishing the diagnosis and cause of hypovolemia and guide further management based on imaging findings.
