Presentation
Known case of empyema. Drain applied for drainage.
Patient Data
There is evidence of subdural rim enhancing abnormal large collection along the right frontoparietal lobes exerting mass effect over adjacent brain parenchyma and midline shift toward the left side.
A bony defect is noted in the right parietal bone with a misplaced tip of the drain.
Scalp tissue emphysema is noted.
Mucoperiosteal thickening is noted in both maxillary sinuses more pronounced on the left side.
The rest of the sinuses and bilateral mastoid air cells appear normal.
Case Discussion
Subdural empyema along the right frontoparietal lobes exerting mass effect over adjacent brain parenchyma with the misplaced tip of the drainage tube. There is bilateral chronic maxillary sinusitis. The causes of subdural empyema could be frontal sinusitis, otomastoiditis, meningitis, previous surgical intervention, or infected subdural hematoma.
