Intracerebral abscess secondary to frontal mucocele with underlying fibrous dysplasia.
In the case illustrated here, an intracranial complication from a frontal sinus mucocele with cerebral abscess was identified in a 45-year-old man who had complained of headaches, obtundation, and fever. The obstruction of the frontal sinus proved to be a localized fibrous dysplasia. Fibrous dysplasia represents a benign idiopathic bone disorder in which cancellous bone is replaced by abnormal fibrous tissue. (3) A frontal sinus mucocele is a rare complication of craniofacial fibrous dysplasia, as was demonstrated in this case by computed tomography (CT) (figure 1) and magnetic resonance imaging (MRI) (figure 2).
