A Rare Cause of Calcified Subdural Empyema and Ventriculitis in a Pediatric Patient: Achromobacter Denitrificans.

Intracranial infections in the pediatric age group are still important causes of morbidity in developing countries. A 2-year-old male patient presented with acute onset of seizures and loss of consciousness to our emergency department with a past history of being followed for hypogammaglobulinemia. Unenhanced computerized tomography scan of the brain revealed a right frontoparietal peripherally calcified extraaxial collection, brain edema and a left sided shift. Contrast enhanced magnetic resonance imaging revealed a subdural empyema associated with the brain parenchyma and the ventricular system. In spite of a decompression procedure and subsequent medical therapy, the patient succumbed on the 9. postoperative day. This is the first case report of a pediatric patient with subdural empyema and ventriculitis due to Achromobacter denitrificans.
