Abstract

Brainstem abscess is a rare and serious condition that requires intensive medical treatment whenever a suggestive diagnosis is made. This report presents the conservative treatment of a middle-aged female patient with a suspected ruptured medulla oblongata abscess. The patient reported a 7-day history of headaches and right-sided weakness. Her neurological symptoms gradually worsened, resulting in right hemiplegia, urinary retention, and swallowing difficulties. Brain magnetic resonance imaging confirmed a severe abscess in the medulla oblongata extending to the upper cervical spinal cord. After 8 weeks of antibiotic and steroid treatment, the patient demonstrated considerable improvement, and follow-up contrast-enhanced magnetic resonance imaging revealed a significant reduction in abscess size. Neurological function recovered nearly to normal, with slight right hemiplegia noted at the 6-month follow-up. These findings suggest that conservative treatment may be feasible in carefully selected patients with a suspected ruptured brainstem abscess and may result in a good outcome; however, treatment decisions should remain individualized.

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
