Abstract:
We report a case of extradural abscess after acute mastoiditis in an 8-years-old boy. The clinic diagnostic of an intracranial complication is difficult. The most common present symptoms are fever, otalgia and otorrhea but are not specific. Neurologic symptoms are suggestive signs of an intracranial complication. We believe that, in acute mastoiditis performance of a CT scan of the brain and temporal bones with intravenous contrast, contribues to the diagnostic of intracranial complication. The diagnostic of thrombosis sinus sigmoid is evoked with slight contrast enhanced sinus sigmoid and failure to opacify. The characterisation of an epidural empyema is a hypodense epidural collection in a contrast-enhanced CT scan. The most common isolated organism are Streptococcus Pneumoniae, Staphylococcus aureus and Pseudomonas aeuginosa. The therapeutic management includes combination of intraveinous antibiotics, mastoidectomy and surgery of the intracranial complication.
Insights
This case study highlights the diagnostic challenges of intracranial complications following acute mastoiditis in children. Early CT scans with contrast are crucial for identifying extradural abscesses and sigmoid sinus thrombosis.
Area of Science:
- Otolaryngology
- Pediatric Neurology
- Radiology
Background:
- Acute mastoiditis can lead to serious intracranial complications.
- Diagnosing these complications clinically is challenging due to non-specific symptoms like fever, otalgia, and otorrhea.
Observation:
- Neurologic symptoms are key indicators of intracranial involvement.
- A case of extradural abscess following acute mastoiditis in an 8-year-old boy is presented.
Findings:
- Contrast-enhanced CT scans of the brain and temporal bones are vital for diagnosing intracranial complications in acute mastoiditis.
- CT findings suggestive of sigmoid sinus thrombosis include slight contrast enhancement and lack of opacification.
- Epidural empyema is characterized by hypodense epidural collections on contrast-enhanced CT.
Implications:
- Prompt diagnosis and management are essential to prevent severe outcomes.
- Treatment involves intravenous antibiotics, mastoidectomy, and surgical intervention for intracranial complications.
- Commonly isolated pathogens include Streptococcus Pneumoniae, Staphylococcus aureus, and Pseudomonas aeruginosa.
