Fenestrations of the intracranial vertebrobasilar system diagnosed by MR angiography
Fenestrations of cerebral arteries are most common in the vertebrobasilar (VB) system, and magnetic resonance (MR) angiographic studies of these variations are sparse.

Magnetic resonance imaging findings of vulvar epithelioid sarcoma
We describe here a case of vulvar epithelioid sarcoma. Epithelioid sarcoma is a malignant appendicular skin tumor that is rarely of vulvar origin. Magnetic resonance imaging (MRI) revealed a solid mass with an...
