A Reversible Lesion of the Corpus Callosum Associated With Bacterial Meningitis

Abstract

We report the rare case of a 22-year-old female admitted for headaches, nausea, and an isolated lesion of the splenium of the corpus callosum (SCC) found on brain magnetic resonance imaging (MRI). A lumbar puncture test was performed, and Pseudomonas aeruginosa meningitis was found. Twenty days before the symptoms, she had spinal anesthesia for a cesarean section. As soon as the diagnosis was made, antibiotic therapy was initiated. Nonetheless, no signs or symptoms were related to this lesion, which spontaneously disappeared within one month on the control MRI. Pseudomonas aeruginosa is a gram-negative bacillus and may cause rare and severe meningitis. Therefore, a history of a neurosurgical procedure or spinal anesthesia should be sought in the anamnesis.
