Intracranial Epidural

Abscess in the Setting of

Sinusitis

Peter Morgenstern, MS4

M.B.

32 RHM c/o headache + retro-orbital pain x 3d

Denies fevers, chills, nausea, vomiting, photophobia, neck stiffness, vision changes, nasal drainage

PMH – Samter’s Triad Asthma

PSxH – Multiple nasal polypectomies (2005, 2007, 2009)

M.B.

Denies smoking, minimal alcohol use

Meds: Ventolin inhaler, fluticasone, flovent

Allergies: Aspirin, Ibuprofen

Exam Afebrile Well-appearing, uncomfortable 2/2 HA HEENT: frontal and maxillary sinus tenderness Neuro: intact

Intracranial Epidural Abscess

Predisposing factors Sinusitis Neurosurgical Procedure Trauma

Numerous causative organisms

Incidence decreasing

Morbidity/Mortality decreasing

Hlavin et al. 1994

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

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.

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

Imaging – Post-op

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

Conclusions

Maintain high clinical suspicion

Image early

Collaborative approach

Aggressive drainage + antibiotic therapy

Are more rigorous studies needed?

Thank You
