title: Thunderclap headache caused by minimally invasive medical procedures: description of 2 cases.
abstract: We report 2 very unusual cases of thunderclap headache complicating minimally invasive medical procedures. In the first case headache developed as the consequence of a pneumocephalus caused by an inadvertent intrathecal puncture during oxygen-ozone therapy for lumbar disk herniation. The second case involved intracranial hypotension, caused by the persistence of the needle, used for epidural anesthesia, and then penetrated in the subarachnoid space.
