=====Brain Abscess after 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 procedure]]s 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.

In atypical courses of a [[chalazion]] the clinical picture requires further diagnosis including evaluation and imaging in otorhinolaryngology and neurology
