Lumbar punctures are frequently used in the diagnostic evaluation of central nervous system diseases such as infections, administration of medications such as chemotherapy and for reduction in intracranial pressure in cases of idiopathic intracranial hypertension. Cerebrospinal fluid (CSF) leak through a dural tear can result in temporary side effects such as headache (postlumbar puncture headache) and backache. Rarely, more severe side effects may occur with neurological deficits if there is an extensive CSF collection or epidural haematoma. However, the majority of these lesions can be managed conservatively.

  • Coma and raised intracranial pressure
  • Pain (neurology)
