Iatrogenic pseudomeningocele is a common complication of cranial surgeries.

Pseudomeningocele may result after brain surgery, spine surgery, or brachial plexus avulsion injury, (preganglionic injury).

Pseudomeningocele as unintended “incidental” durotomy: 0.7–2% ¹⁾ (may appear similar radiographically to a spinal epidural abscess (SEA), but post-op SEA often enhances, is more irregular, and is associated with muscle edema).

Pseudomeningocele is a cause of Failed back surgery syndrome.
