A and B are brain CT imges at 48 and 56 years of age that revealed intracranial hemorrhage (arrowheads). A fluid-attenuated inversion recovery (FLAIR) sagittal image (C) and a postgadolinium-enhanced T1 sagittal image (D) showed hyperintensities in the dorsal medulla along the fourth ventricle (arrow). A T2-weighted axial image (E) showed hyperintensities (arrow) in the dorsal medulla along the fourth ventricle. F is a brain CT image at 59 years of age showing recurrent intracranial hemorrhage (arrowheads) that occurred concurrently with an attack of neuromyelitis optica spectrum disorder (NMOSD).

The patient was a woman without hypertension who had previously experienced intracranial hemorrhage twice at 48 and 56 years of age (Fig. 1A and B). T2-weighted (Fig. 1E) imaging showed areas of hyperintensity in the dorsal medulla along the fourth ventricle. Brain computer tomography (CT) (Fig. 1F) showed multiple intracranial bleeding in the right frontal lobe and right parietal lobe.
