A 70-year-old female patient was referred to our emergency department complaining about a new onset of back pain and malignant hypertension. The initially performed CTA, on a 16-slice single source CT with 100 mL contrast media, revealed a Stanford B dissection. The patient was again referred to our department for re-evaluation, 12 hours later, with progressive back pain, a new onset of chest pain and increasing blood creatinine levels.
