- Abstract
This is similar to a recently described type of spontaneous CSF leak in patients with SIH, the spinal CSF-venous fistula.2 Brain sagging is seen in about half of patients with SIH on MRI. Magnetic resonance imaging (MRI) was normal (Fig, A) except for a subcranial cerebrospinal fluid (CSF) collection. Brain sagging also is a common finding in patients with lumboperitoneal shunts3 and also can be seen with CSF shunts from the posterior fossa to the peritoneum.4 This is a similar pathophysiologic mechanism to that seen in our patient, that is, bulk CSF flow from the posterior fossa diverting CSF from the spinal subarachnoid space.
