Fig. 1 Patient 1 with arterialised DVA. T1-weighted MRI (a) shows
right parietal haematoma accompanied by a signal void vessel
adjacent to the haematoma, which suggests possible vascular
malformation. Cerebral angiography at right anterior oblique projection
in mid-arterial (b) and venous (c) phase confirm the presence of
arterialised DVA. Please note early opacification of caput medusae
and collector vein of the DVA in arterial phase of the angiography (b).
T2-weighted MRI 2.5 years after radiosurgery (d) reveals extensive
vasogenic oedema surrounding an area with mixed signal intensities in
the right parietal region, consistent with radiation necrosis associated
with haematoma. Control angiography (e) shows significantly reduced
(still continuing) shunting in the arterialised DVA with patent but
compressed collector vein which is probably responsible for the
concomitant haemorrhage


Fig. 2 Patient 2 with
arterialised DVA. Contrastenhanced
T1-weighted MRI (a)
shows a caput medusae in the
left frontal region. CT angiography
(b) further depicts the
components of the DVA; the
collector vein, and the caput
medusae. The left carotid
angiogram AP view in early
arterial (c) and venous (d) phase
with typical features of the
arterialised DVA. Please note
opacification of the caput
medusae in early arterial
phase (c)



Fig. 3 Patient 6 with DVA associated with AVM. T1-weighted MRI
(a) showing left parietal haematoma and adjoining signal void vessels.
Cerebral angiography early (b) and late (c) arterial phase. There is a
small AVM nidus (thin arrow) fed by the lenticulostriate arteries and
draining towards the caput medusae located in the left sylvian region
with concomitant early opacification of the collector vein of DVA.
Please note the inadvertently overlapped draining vein of the AVM
(thinner vessel towards the caput medusae) and collector vein of the
DVA (thicker vessel towards the internal cerebral vein; thick arrow).
After radiosurgery, control cerebral angiography in the mid-arterial (d)
and venous (e) phase shows disappearance of the AVM nidus.
However, the collector vein (arrow) is still visible in the arterial
phase with diminished calibration



Fig. 4 Patient 7 with DVA associated with AVM. The right carotid
angiogram at right anterior oblique projection before (a) and after (b)
embolisation. There are a caput medusae and an AVM nidus inside the
caput medusae which is fed by the distal two branches of the anterior
cerebral artery. Please note a filling defect in the caput medusae due to
the large parenchymal haematoma. Superselective microcatheter
injection at lateral projection (c) shows a nidal compartment of the
AVM. Post-operative lateral carotid angiography in the late arterial
phase (d) shows a parenchymal defect after resection of the DVA
together with corresponding gyrus. A sixth-month follow-up angiogram
at right anterior oblique projection (e) and coronal Flair MRI (f)
confirm disappearance of complex vascular lesion and corresponding
parenchymal defect
