Suboccipital pseudomeningocele treatment

Suboccipital pseudomeningocele treatment options (up to 67% require permanent cerebrospinal fluid drainage 1)):

1. noninvasive measures: expectant management, fluid restriction diet, head wrapping, keeping HOB elevated, acetazolamide. Steroids may be used if aseptic meningitis is suspected

2. percutaneous aspiration: “tap and wrap.” Risks introducing bacteria, causing infection

3. direct surgical exploration with multilayer re-closure

4. lumbar drainage: effective only if pseudomeningocele communicates with the subarachnoid space.

✖ May produce acute posterior fossa syndrome (H/A, nausea, vomiting, ataxia…) 2) especially if the pseudomeningocele doesn’t communicate. Symptoms usually resolve with prompt discontinuation of lumbar drainage 3) 4). Other potential complications: vagal nerve palsy, tonsillar herniation, subdural hematoma, kinking of PCA → stroke. Drainage options:

a) External lumbar cerebrospinal fluid drainage (temporary)

b) Lumboperitoneal shunt (permanent)

5. Ventricular drainage

a) EVD (temporary)

b) shunt (permanent)
