Abstract:
A 77-year-old man developed progressive sensory and motor symptoms in the right lower leg. Examination showed neurological deficits in the distribution of the right tibial and common peroneal nerves. Swellings in both popliteal fossae were palpated. Investigation showed these to be large thrombosed aneurysms. On surgical examination on the right, the aneurysm was found to be compressing the distal sciatic nerve.
