MRI head. Selected axial T2 weighted images of the supratentorial (A) and infratentorial (C) compartment that appear normal. However, the corresponding axial susceptibility weighted images (B and D) demonstrate extensive supratentorial and infratentorial blooming artifact reflecting sulcal pial hemosiderosis

The susceptibility weighted images demonstrated extensive supratentorial and infratentorial hemosiderosis (Figure 1).
MRI spine, selected images. Sagittal T1 pre-(A) and post-(B) contrast, T2 weighted (C) and axial T1 postcontrast (D) images demonstrate T1-isointense, T2-hyperintense intradural and extramedullary lesion centered on the filum terminale which enhances avidly following contrast administration. Radiological appearances are compatible with a myxopapillary ependymoma

This revealed an intradural enhancing lesion centered on the filum terminale that was deemed the likely source of the bleeding (Figure 2).
