MRI Brain Imaging and Acridine Orange (AO) Stains of CSF Samples Prior to Ciprofloxacin. A: MRI brain imaging of the patient axial and coronal views. Multiple discontinuous fluid filled cysts are noted throughout the brain with minimal remaining brain parenchyma. B: Sections of representative microscopic slides of patient’s CSF AO stains of two separate CSF collections obtained 1–2 days apart. Black arrows locate the rod-shaped intact organisms. The connected rods are consistent with images of actively dividing organisms such as E. coli
