Comparison of endovascular versus open repair of abdominal aortic aneurysms: a review.

The purpose of this review is to highlight the indications, complications, and outcomes observed with endovascular or open repair for abdominal aortic aneurysms. We selected literature published during 2005 to 2008, encompassing a research period from 1987 to 2005 which compared these 2 techniques and followed various outcomes of morbidity and mortality.

Conventional intramedullary chondrosarcoma with subarticular involvement.

A 78-year-old female patient with a lesion in the distal tibia is shown to have conventional intramedullary chondrosarcoma. Typical considerations for this end-of-bone neoplastic lesion are giant cell tumor, clear cell chondrosarcoma, and chondroblastoma. Salient clinical and radiographic features and behavior of this lesion broaden the typical view of conventional intramedullary chondrosarcoma.

Magnetic resonance imaging of idiopathic herniation of the cuneus gyrus.

A 65-year-old woman presenting with chronic headaches and without overt visual symptomatology was found to have herniation of the cuneus gyrus into the superior cerebellar cistern. Only one prior case of idiopathic brain herniation has been described, in which the parahippocampal gyrus herniated into the ambient cistern. In that case a biopsy was performed as the herniation was mistaken for a tumor.
