subdural empyema

The underlying arachnoid and subarachnoid spaces are usually unaffected, but a large subdural empyema may produce a mass effect.

CNS infections can be isolated from subdural empyema and brain abscesses which are a result of chronic infections.

Appropriate therapy should take into account the primary source of infection as well as possible associated complications such as brain abscess, meningitis, or subdural empyema.

These often cause subdural empyema, and brain abscess, and rarely cause epidural abscess and meningitis.

Bacterial or occasionally fungal infection of the skull bones or air sinuses can spread to the subdural space, producing a subdural empyema.

Pott's Puffy tumor can be associated with cortical vein thrombosis, epidural abscess, subdural empyema, and brain abscess.

Complications of untreated CST include extension of thrombus to other dural venous sinuses, carotid thrombosis with concomitant strokes, subdural empyema, brain abscess, or meningitis.
