Overview
Subdural empyema, also referred to as subdural abscess, pachymeningitis interna and circumscript meningitis, is a life-threatening infection.[1] It consists of a localised collection of purulent material, usually unilateral, between the dura mater and the arachnoid mater and accounts for about 15-22% of the reported focal intracranial infections. The empyema may develop intracranially (about 95%) or in the spinal canal (about 5%), and in both cases, it constitutes a medical and neurosurgical emergency.[2] Following clinical evaluation, proper history taking, physical examinations and laboratory test results, the diagnosis of subdural empyema has to be confirmed by imaging studies.
Cranial Ultrasonography
Cranial ultrasonography is usually the first imaging mode to be ordered in infants because it's safe, cost-effective and usually differentiates subdural empyema from anechoic reactive subdural effusion. [3]
Other Tests
Other imaging tests, such as the radionuclide brain scanning and angiography have been helpful in reaching the diagnosis of subdural empyema in certain situations, however their effectiveness is much inferior than that of the MRI or CT scanning. [1]
