Sudden Right Lower Limb Paralysis: An Uncommon Presentation of Type A Aortic Dissection.

Acute aortic dissection is a rare and life-threatening emergency, with fatal outcomes often resulting from delayed or missed diagnoses. Type A aortic dissection, which typically presents with acute chest pain radiating to the back, is the most common cause of death associated with aortic lesions and requires urgent surgical intervention. We present an unusual case of type A aortic dissection that manifested solely with sudden paralysis and tingling of the right lower limb, without chest or back pain. Despite timely diagnosis in the emergency department, emergency surgical intervention failed to save the patient's life.
