Abstract

In patients with sudden severe headache and a negative computed tomography CT scan, a lumbar puncture LP is performed to rule in or out a subarachnoid haemorrhage SAH, but this procedure is under debate. In a hospital-based series of 30 patients with sudden headache, a negative CT scan but a positive LP defined as detection of bilirubin >0.05 at wavelength 458 nm, we studied the chance of harbouring an aneurysm and the clinical outcome. Aneurysms were found in none of both patients who presented within 3 days, in 8 of the 18 44% who presented within 4–7 days and in 5 of the 10 50% who presented within 8–14 days. Of the 13 patients with an aneurysm, 3 23% had poor outcome. In patients who present late after sudden headache, the yield in terms of aneurysms is high in those who have a positive lumbar puncture. In patients with an aneurysm as cause of the positive lumbar puncture, outcome is in the same range as in SAH patients admitted in good clinical condition.
