Intracranial Epidural Abscess
Predisposing factors Sinusitis Neurosurgical Procedure Trauma
Numerous causative organisms
Incidence decreasing
Morbidity/Mortality decreasing
Hlavin et al. 1994
![Page 8: Intracranial Epidural Abscess in the Setting of Sinusitis Peter Morgenstern, MS4.](https://reader030.fdocuments.in/reader030/viewer/2022032612/56649edb5503460f94beb8b0/html5/thumbnails/8.jpg)
Presentation and Diagnosis
Fever, headache, nausea/Vomiting
Confusion, agitation, seizures, hemiparesis, cranial neuropathies
Periorbital cellulitis or frontal edema (45%)1
CT and MRI
Other studies
Pradilla et al. 2009
![Page 9: Intracranial Epidural Abscess in the Setting of Sinusitis Peter Morgenstern, MS4.](https://reader030.fdocuments.in/reader030/viewer/2022032612/56649edb5503460f94beb8b0/html5/thumbnails/9.jpg)
Management
Hastings 1907

Surgical Drainage – ENT and Neurosurgical
Trans-ethmoidal drainage1
Removal of infected bone, possible CSF diversion ENT in the acute setting2
Medical Antibiotics Possible AEDs, corticosteroids, hyperosmolar fluids Hyperbaric oxygen therapy3
Role for conservative approach4
Management
1. Patron et al. 20102. Delgaudio et al. 20103. Heran et al. 20034. Baechli et al. 2008

Outcomes
Historically poor
Favorable in most cases today
Positive predictors young age, - encephalopathy, neuro deficit, comorbidities
Negative predictors – herniation, delayed neuroimaging, delayed diagnosis

M.B.
Urgent bifrontal craniotomy
Broad-spectrum antibiotics after OR culture
Vancomycin, Gentamycin, Metronidazole
Consult with ENT and ID
Modify antibiotic coverage based on culture
![Page 14: Intracranial Epidural Abscess in the Setting of Sinusitis Peter Morgenstern, MS4.](https://reader030.fdocuments.in/reader030/viewer/2022032612/56649edb5503460f94beb8b0/html5/thumbnails/14.jpg)
Imaging – Post-op
![Page 15: Intracranial Epidural Abscess in the Setting of Sinusitis Peter Morgenstern, MS4.](https://reader030.fdocuments.in/reader030/viewer/2022032612/56649edb5503460f94beb8b0/html5/thumbnails/15.jpg)
M.B.
Uncomplicated post-op course
Notable improvement in symptoms
Discharged on POD #7
4-6 week course of IV vancomycin and ceftriaxone pending cultures
Culture: pan-sensitive coagulase negative staphylococcus
![Page 16: Intracranial Epidural Abscess in the Setting of Sinusitis Peter Morgenstern, MS4.](https://reader030.fdocuments.in/reader030/viewer/2022032612/56649edb5503460f94beb8b0/html5/thumbnails/16.jpg)
Conclusions
Maintain high clinical suspicion
Image early
Collaborative approach
Aggressive drainage + antibiotic therapy
Are more rigorous studies needed?
