Rhinoorbitocerebral actinomycosis.
OBJECTIVE
To report a case of actinomycotic orbital abscess with subdural empyema and pansinusitis, an unusual presentation of a rarely seen infection.


METHODS
Case report.


RESULTS
A 35-year-old man sought treatment for signs and symptoms of an orbital abscess 22 days after a dental extraction. Computed tomography demonstrated a left orbital abscess with left pansinusitis and a large subdural empyema. Surgical clearance of all purulent material was done followed by prolonged penicillin therapy. Culture of pus from all sources yielded Actinomycosis israelii. At the time of discharge and 1-month follow-up, the patient had 20/20 vision with no neurologic deficits.


CONCLUSIONS
In orbital infections with atypical presentations, unusual pathogens should be considered as the causative agents.
