CONCLUSIONS:
ISH is a rare but serious complication following spinal anesthesia and
may mimic PDPH. Cases presenting solely with headaches during the
postpartum period are often assumed to be benign, and conditions such as
ISH may be masked initially resulting in a delay in diagnosis and
intervention. Therefore, with proper neurological examination and
regular follow up the possibility of an ISH must be kept in mind when
evaluating these cases.
