title: [Widespread brainstem abscess resolved with medical therapy].
abstract: The brainstem is an uncommon site of a brain abscess. Such lesions, which were invariably fatal, changed with the arrival of computed tomography and magnetic resonance imaging (MRI). These not only helped in the diagnosis but also in treatment management. A 51-year old patient was diagnosed of widespread pontomesencephalic abscess. He was admitted with a clinical picture of dizziness, headache and involvement of multiple cranial nerves with near complete ophthalmoplegia and cerebellar syndrome in the side of the lesion and contralateral hemiplegia. Microbiologic investigations were negative and the medical management decided was broad spectrum antibiotic and periodic MRI controls. The length of the lesion decreased (from 4 cm in diameter to 0.5 cm) with progressive improvement of the neurological deficits. Treatment of large brainstem abscesses includes primary antibiotic therapy combined with stereotaxic drainage, but in individual cases empirical medical therapy can be effective. Sequential MRI examinations are very important for monitoring treatment efficacy.
