case_images: CT scan showed subarachnoid hemorrhage with ventricular enlargement, and computed tomographic angiography showed a left posterior communicating artery aneurysm [Figure 3]. Cerebrospinal fluid (CSF) analysis reported a pinkish/red color, red blood cell count of 1777 without any white blood cells, protein 22.8, glucose 137, and negative CSF Gram stain.
