RESUMO
We present the case of a 52-year-old male who arrived at the Emergency Department after several ground-level falls in the past month. He complained of urinary incontinence, mild confusion, headaches, and appetite loss in the past month as well. Brain computed tomography (CT) and magnetic resonance imaging (MRI) were performed, which showed enlarged ventricles with moderately prominent cortical atrophy and no acute abnormalities. It was decided to conduct a cisternogram study with serial scans. The study showed a type IIIa cerebrospinal fluid (CSF) flow pattern at 24 hours. At the 48- and 72-hour marks, the study displayed an absence of radiotracer activity within the ventricles, while all the activity was concentrated within the cerebral cortices. These findings successfully ruled out normal pressure hydrocephalus (NPH) due to the highly specific indication of normal CSF circulation pattern. The patient was treated with thiamine and advised to quit drinking, as well as return for follow-up in one month as an outpatient for a repeat brain CT.
