Sonographic diagnosis of ulnar artery aneurysm in hypothenar hammer syndrome: report of 2 cases.

Giant aneurysm of the ulnar artery in the palm treated by resection and microvascular reconstruction

“…There have been several previous reports about the use of an arteriogram and colour Doppler sonographic imaging in such cases [9], but we could not find any report about MR imaging for palmar aneurysms. A true aneurysm usually has flow artefacts along the phase encoding on a T2-weighted MR image as a result of the pulsations, which is helpful in distinguishing the aneurysm preoperatively from other soft tissue tumours.…”

Hypothenar Hammer Syndrome

“…25 Since these reports, sonography has been established as the first imaging modality used to make the diagnosis, and it should be considered for patients with digital ischemia and a painful mass in the hand. 26 As demonstrated in the present case report, the combination of grayscale ultrasound and color Doppler will identify arterial occlusion and aneurysm/pseudoaneurysm, even when thrombosis has occurred in the aneurysm. On the gray-scale image, you can see mural thrombus in the wall of the aneurysm.…”

“…Although the diagnosis is usually confirmed angiographically, an angiogram cannot show whether arterial occlusion is associated with an aneurysm, and that may influence treatment options. 26 For example, in the case with critical digital ischemia, if the occluded segment is acute and not aneurysmal, then thrombolysis can be performed without subsequent surgery. If the occluded segment involves an aneurysm, then subsequent surgery is indicated ( Fig.…”

Hypothenar hammer syndrome: Gray‐scale and color Doppler sonographic appearances

“…Patients may present with pain in the palm, paresthesia, numbness, and signs of vascular insufficiency such as coldness, pallor, discoloration, and blanching of the affected ulnar sided fingers, sometimes in combination with Raynaud's syndrome. 6 Usually described in men with industrial occupations involving repetitive blunt trauma or single severe trauma to the hands, [6][7][8] true or false aneurysms of the hand have also been described in athletes with sports-related injuries, including handball players, baseball catchers, and dancers. 5 Many cases are probably asymptomatic, and the condition is believed to be underdiagnosed.…”
