Intracranial infections, especially subdural empyema, due to salmonella are rare. Subdural empyema caused by Salmonella paratyphi A has been documented only once earlier in the literature. Hence, we report a case of subdural empyema and osteomyelitis of cranial vault due to S. paratyphi A. A 42- year-old male presented with headache and purulent discharge from right parietal burr hole wound site. Patient gave a history of head injury two years ago. He underwent burr hole evacuation of chronic subdural haematoma, excision of outer membrane and right parietal craniectomy. The cultures grew S. paratyphi A. Recovery was uneventful following surgical intervention and antibiotic therapy.
