intrakranielle arteriovenöse Malformationen

Infant with

heart failure. Axial T2 MRI of the brain (above left) shows large vascular flow voids representing the nidus of the lesion along the right hemisphere of the brain and a dilated sagittal sinus. Sagittal US of the midline of the brain (above right) shows a large vascular structure with mixed arterial and venous flow within it that is compressing and displacing the sagittal sinus beneath it. MR angiogram with contrast of the brain (below left) shows a large nidus of arterial vessels along the right cerebral hemisphere fed primarily by the right middle cerebral artery that rapidly drain into a dilated sagittal sinus on the MR venogram (below right).The diagnosis was intracranial arteriovenous malformation with arteriovenous fistula.

Brain stones

revisited—between a rock and a hard place. Axial CT in bone windows (a) and 3D reconstruction (b) of a 33-year-old male with temporal lobe epilepsy. The large amorphous calcification seen at the base of the left temporal lobe in this NCECT represents a known case of an embolised AV malformation. Calcifications are known to appear in 25–30 % of cases in close conjuction with serpentine vessels or within adjacent brain parenchyma

A cerebral

arteriovenous malformation mistakenly diagnosed as dry eye and glaucoma: a case report. The appearance of the both eye There was no obvious hyperaemia in the left eyes (a). The right eye exhibits severe diffuse corkscrew hyperaemia (b-d). Imaging revealed that the AVM (The red arrow) is fed by the posterior cerebral artery and pericallosal artery and drains to the medial atrial vein (e)
