title: The double lumen: a pathognomonic angiographic sign of arterial dissection?
abstract: A case is reported which questions the absolute significance of the "double-lumen sign" in the diagnosis of arterial dissection. I suggest that when demonstrated in isolation, this sign should be interpreted with caution, giving consideration to the possibility of arterial fenestration, and appropriate diagnostic measures implemented.
