Abstract
Papillary glioneuronal tumor (PGNT) is a low-grade biphasic tumor that is composed of glial fibrillary acidic protein (GFAP)-positive glial cells and synaptophysin-positive neurons. We report a case of PGNT occurring in the right occipital lobe of a 48-year-old woman who presented with acute headache and left homonymous hemianopsia, the latter of which was difficult to distinguish from malignant brain tumors because of peritumoral brain edema, intratumoral hemorrhage, and intraoperative fluorescence staining. PGNT should be included as one of the differential diagnoses in cases where the tumor shows hemorrhagic change despite decreased perfusion in arterial spin labeling MRI.
期刊介绍：

The subject areas cover the following: molecular/cell biology; biochemistry; basic medicine; clinical medicine; veterinary medicine; clinical nutrition and food sciences; medical engineering; nursing sciences; laboratory medicine; clinical psychology; medical education.
Basically, contributors are limited to members of Tottori University and Tottori University Hospital. Researchers outside the above-mentioned university community may also submit papers on the recommendation of a professor, an associate professor, or a junior associate professor at this university community.
Articles are classified into four categories: review articles, original articles, patient reports, and short communications.
