Figure 1. Brain MRI fin-
dings: superficial siderosis
can be identified on T2 TSE
images (A, C, arrows) and
is better visible on T2* GRE
sequences (F, G, arrows)
as linear hypointensities
along the cortex. These fin-
dings are more consistent in
I L the posterior cranial fossa,
with atrophy of superior vermis (D,
arrow). Note the remodeling of the
dura and of the adjacent bone along
the skull base, in particular at the le-
vel of the Meckel caves (A, C, D, H,
arrowheads). Nodules are present
along the ependyma of the ventri-
cles (I, arrows); cerebral sulci have
an abnormal FLAIR hyperintensity
(I, arrowheads), with associated li-
near and pseudo-nodular enhance-
ment in post-contrast T1 weighted
sequences (E, arrowheads). An an-
gio-MRI with 3D-TOF sequences
excludes vascular alterations as
possible sources of bleeding (L).
