This article reports a 56 year old male with a space occupying lesion under the left frontal skull plate. On MRI, there is an abnormal signal shadow resembling a circular mass with abundant blood supply in the left frontal region of the brain. On T1WI, it shows isolow signal, while on T2WI and fluid attenuation inversion recovery sequence (FLAIR), it shows slightly high signal. There are empty blood vessels inside, and surrounding edema is seen. DWI shows no diffusion restriction and low signal, while on ADC image, it shows high signal. The pathological diagnosis is angioblastoma, WHO grade I.
