Staphylococcus aureus meningitis secondary to occult spinal extradural abscess.

UNLABELLED: We report a rare case of spinal extradural abscess presenting as Staphylococcus aureus meningitis in a previously well child. After initial improvement with intravenous antibiotics the patient clinically deteriorated in a non-specific manner. Magnetic resonance imaging (MRI) scan of the spine revealed an occult spinal extradural abscess and urgent neurosurgical laminectomy led to full recovery. No evidence of an underlying spinal abnormality or immunodeficiency was demonstrated on investigation. A high index of suspicion is required in these cases due to the frequent absence in children of classic symptoms of spinal extradural abscess.
CONCLUSION: we advise an urgent MRI of the head and spine in such unexplained cases of Staphylococcus aureus meningitis, to allow early diagnosis and management of occult underlying pathology. Such an approach will minimise the risk of potentially catastrophic neurological sequelae.
