Assess and correlate the clinical presentation, cranial CT and lumbar puncture (LP) findings in patients presenting with acute headache, clinically suspicious of subarachnoid haemorrhage, from the Accident and Emergency (A/E) department of a main teaching hospital. ⋯ This study reviews the varying clinical presentations of SAH and the difficulty in clinically diagnosing SAH where headache is the only symptom. We review the wide differential diagnosis on cranial CT and on discharge of patients presenting with symptoms clinically suspicious of SAH. In addition this study identfies a high proportion of patients without detailed clinical notes and discharged without a diagnosis. The study reaffirms that a significant proportion of patients are diagnosed on LP and stress the importance of performing a LP in all cases with clinically suspected SAH with a negative CT This latter point requires highlighting in the medical literature as over half of eligible patients did not have a LP performed despite this being accepted diagnostic protocol.
