Unusual course of a chalazion
A 15-year-old boy with frontal and ethmoidal sinusitis with inflammatory orbital infiltration and subacute eyelid swelling. The cerebral imaging showed an encapsulated brain abscess so that an urgent surgical removal of the abscess cavity was indicated. After several neurosurgical procedures a complete remission of the abscess could be achieved. In spite of the large abscess in the frontal lobe the boy never showed any neurological symptoms or psychiatric symptoms.
