Extradural haematoma complicating lumbar puncture following a craniotomy. A case report.

Background: This case report illustrates the development of an intracranial extradural haematoma (EDH) as an uncommon complication of a lumbar puncture.
Clinical Presentation: A 10-year-old girl operated for intra-third ventricular cysticercosis developed postlumbar puncture headache after a drainage lumbar puncture (LP) on the 7th postoperative day. CT scan revealed a right frontal EDH away from the operative site.
Intervention: The child was managed conservatively in view of her preserved sensorium.
Results: The child had an uneventful recovery. Follow-up CT scans showed resolution of the haematoma.
Conclusions: LP, though considered to be a safe procedure, may rarely be associated with a potentially lethal intracranial haematoma, which can be managed successfully if diagnosed at an early stage.
