A 52-year-old man presented with a pontine abscess manifesting as diplopia and right hemiparesis initially misdiagnosed as a brain stem glioma. His condition worsened rapidly. Magnetic resonance (MR) imaging revealed a rapidly growing mass lesion in the pons. At first the patient was treated with antibiotics, but his consciousness deteriorated. The abscess was resolved after ultrasound-guided aspiration via a suboccipital approach and appropriate antibiotic therapy. We believe that this is the first report of a favorable outcome in a patient with a brain stem abscess treated by ultrasound- guided aspiration. The value of ultrasound-guided aspiration with color Doppler is explained with a review of the relevant literature.
