The dural tail of intracranial meningiomas on fluid-attenuated inversion-recovery images.

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. ...
