title: Colour duplex sonographic and multislice spiral CT angiographic diagnosis of ulnar artery aneurysm in hypothenar hammer syndrome.
abstract: We report a case of hypothenar hammer syndrome secondary to a thrombosed aneurysm of the ulnar artery in a 36-year-old patient presenting with pain due to compression of the ulnar nerve in the Guyon's canal. The initial diagnosis was made by colour Duplex sonography but complete assessment of the thrombosed aneurysm was performed by multislice spiral CT angiography (msCTa). This case illustrates the potential of msCT as an alternative to conventional arteriography.
