To the Editor.—
I enjoyed reading Dr. Hussey's editorial "Popliteal Cyst: Diagnostic Dilemmas" (230:589, 1974) but believe his last paragraph requires some comments.Having had considerable experience with both elective and emergency surgery on popliteal aneurysms, I would strongly advise that this diagnosis not be made by the insertion of an exploring needle into the lump. Bleeding might be difficult to stop and the usually present clot might be dislocated. If there is strong suspicion of a popliteal aneurysm, careful clinical examination and possibly an arteriogram will always make the diagnosis.Dr. Singer is probably right, especially as regards dislodgement of a clot from an aneurysm that does not exhibit a definite expansile pulsation. I must have been lucky years ago.
