title: Painless aortic dissection presenting as high paraplegia: a case report.
abstract: Acute aortic dissection is a catastrophic episode that usually presents as a sudden, painful, ripping sensation in the chest or back. Physical findings may include loss of pulses and aortic regurgitation. It is associated with neurologic sequelae in as many as one third of patients. Painless dissection occurs in 5% of patients. We report a case of painless aortic dissection, presenting as acute paraplegia. The patient was a 77-year-old woman who presented with paraplegia, with no chest or back pain. On examination, strength was 5/5 in both upper extremities and 0/5 in both lower extremities. Deep tendon reflexes were absent in her legs. She had no voluntary anal contraction. Sensation was absent from T6 through S5. Computed tomography of the chest revealed a type A dissecting aneurysm. The vascular supply to the spinal cord and the differential diagnosis for new onset paraplegia are discussed.
