An 81-year-old woman complained of severe right leg claudication in 2000. She had undergone inverted Y-graft placement for infrarenal abdominal aortic aneurysm in 1998. Magnetic resonance angiography (MRA) revealed severe stenosis at the right common iliac graft.

Imaging features of myoepithelioma arising from the hard palate. A case report.

A 53-year-old Japanese woman presented with a mass of the hard palate that was histologically diagnosed as myoepithelioma. By CT, the well-demarcated ovoid isodense mass showed faint contrast enhancement. By MR imaging, the mass was homogeneous and isointense on T1-weighted images with homogeneous enhancement after administration of contrast material and markedly hyperintense on T2-weighted images.

Renal arteriovenous malformations: CT features.

The CT and clinical features of six patients with congenital renal arteriovenous malformation (RAVM) were reviewed to determine the characteristics of this condition. The most common symptom was hematuria. The CT images were characterized by masses of vascular density located in the renal sinus and surrounding the pelvicaliceal system with or without dilated renal veins.
