Axial magnetic resonance imaging of the brain showing hyperintensity in the subarachnoid space on T2 FLAIR (A) with a normal Time Of Flight (TOF) angiography. Sagittal magnetic resonance imaging with T2 (C,D) and T1 (E) spin echo (TSE) sequences reveals intradural and epidural hemorrhage (yellow arrows) and hypersignal of the spinal cord from T11 to L1 of the terminal cone (red arrow).

Then, a cerebral magnetic resonance imaging (MRI) was performed showing on axial images hyperintensity in the subarachnoid compatible with a peri mesencephalic subarachnoid hemorrhage space on T2 FLAIR with a normal time of flight (TOF) angiography (Figure 1A).
Medullar axial T2 (A) and post-enhanced T1 (B) images shows flow voids lateral to spinal cord with a serpentine enhancing veins on the cord surface (arrows).
