[edit] Discussion of Intracranial hypotension

  • Intracranial hypotension results from leakeage of cerebrospinal fluid.
  • Intracranial hypotension may be caused by a skull fracture with leakage of cerebrospinal fluid. More often, it may follow an uncomplicated lumbar puncture; however, in many cases it is idiopathic.
  • Patients often present with postural headaches.

[edit] Imaging Findings for Intracranial hypotension

  • MR imaging is relatively sensitive and specific in the detection of benign or spontaneous intracranial hypotension.
  • The classic imaging features include:
    • Thick linear enhancement of the pachymeninges, no enhancement of the sulci or brain surface, enhancement above and below the tentorium
    • Enlargement of the pituitary gland
    • Descent of the brain (low cerebellar tonsils)
    • Subdural effusions (or hemorrhage in some patients)
