Abstract:
:Intracranial pial and dural arteriovenous shunts may exist at different sites in the same patient. The etiology, natural history and treatment of these associated conditions have not been completely determined. We reviewed the records of 765 cases of pial arteriovenous malformation and 137 dural arteriovenous fistulae and malformations. We selected eight patients with both pial and dural arteriovenous shunts, separate anatomically, with distinct feeding arteries and draining veins, representing 1% of pial and 17% of dural shunts. Presentation was related to the dural lesion in 5 cases (62.5 %) and to the pial malformation in three (37.5%). Treatment of these lesions should be considered separately based on their angio-architecture and natural history.

NEURORADIOLOGY文献大全abstract::We report CT and MRI findings in two patients with ameloblastoma. One case had a multilocular mixed lesion and the other had a unilocular solid pattern. The second case is probably one of the youngest reported. CT and MRI can be used to delineate and show the extent of the tumour. ...
