title: Right calf claudication revealing leriche syndrome presenting as right sciatic neuropathy.
abstract: The syndrome of aortoiliac occlusive disease, also known as Leriche syndrome, is characterized by claudication, pain, and diminished femoral pulse. We highlight an unusual case of right sciatic neuropathy caused by Leriche syndrome, which was initially misdiagnosed. A 52-year-old male, with a past medical history of hypertension and bony fusion of the thoracolumbar spine, visited our hospital complaining of right leg pain and claudication, and was initially diagnosed with spinal stenosis. The following electrophysiologic findings showed right sciatic neuropathy; but his symptom was not relieved, despite medications for neuropathy. A computed tomography angiography of the lower extremities revealed the occlusion of the infrarenal abdominal aorta, and bilateral common iliac and right external iliac arteries. All these findings suggested omitted sciatic neuropathy associated with Leriche syndrome, and the patient underwent a bilateral axillo-femoral and femoro-femoral bypass graft.
