A case of ochronosis: MRI of the lumbar spine.

abstract：PURPOSE:Coiling associated with placement of a self-expandable intracranial stent has improved the treatment of intracranial wide-necked aneurysms. Little is known, however, about the durability of this treatment. The purpose of this report is to present our experience with the LEO stent and to evaluate the complicatio...
