Interhemispheric subdural empyema: neuroradiological diagnosis.
A case of subdural empyema situated in the interhemispheric subdural space is described. CT scan is useful in the diagnosis and follow-up of intracranial inflammatory pathology. Selective angiography was helpful in the compartmental localization of the abscess in the interhemispheric subdural space, adjacent to the falx and tentorium by virtue of the hypertrophied tentorial meningeal arteries and vascular displacement. CT scans are also useful in follow-up of cerebral abscess after micropaque barium has been injected into the cavity as in this patient.
