RESUMEN
OBJECTIVE: To present a patient with brainstem abscess treated by microsurgical resection. CASE PRESENTATION: A 53-years-old female patient admitted to the neurosurgical department in a severe condition with symptoms of intracranial hypertension, hyperthermia, general infectious signs and laboratory manifestations of infectious process. Contrast-enhanced MRI revealed a large brainstem lesion (abscess). Retrosigmoid craniotomy with total microsurgical resection of the abscess was performed. External ventricular drainage was incerted on the second postoperative day due to progressive hydrocephalus with clinical deterioration, it was removed in 8 days. Slow positive dynamics was observed in postoperative period. The patient was discharged in 2 weeks after surgery. CONCLUSION: There are no established algorithm for the treatment of brainstem abscesses. Therapeutic approach is advisable for small abscesses. There are 2 neurosurgical options for this lesion: stereotactic drainage and microsurgical resection with or without external ventricular drainage. Treatment strategy depends on location and size of abscess, as well as clinical state of the patient.
