AbstractSubdural hematoma may occur as rare, although intervention- specific complications of accidental dural puncture by neuroaxial block. Bleeding may be caused by rapid cerebrospinal fluid loss related to traction on fragile intracranial bridging veins. This article reports a case of postdural puncture headache in a 43-year-old woman after accidental dural puncture during attempted placement of an epidural catheter for induction of abortion. Bed rest, analgesics, theophylline and hydration were to no avail and only a blood patch improved the headaches. The patient presented 7 weeks later with headache and left-sided hemiplegia. Magnetic resonance imaging showed a right frontoparietal subdural intracranial hematoma which had to be surgically evacuated. The patient recovered completely. Intracranial hematoma is a rare but serious complication of central neuroaxial block. According to current German jurisdiction this risk must be addressed when informed consent is obtained. Intracranial hematoma should be considered in the differential diagnosis of atypical headache and neurological signs (e.g. focal motor and sensory deficits and seizures) following neuroaxial block and adequate image diagnostics should be carried out without delay.
