Rupture of Thoracic Aneurysm and Aortic Dissection With Manifestation of Subcutaneous Hematoma

We report a case with rare signs of subcutaneous hematoma, ecchymoses, and pleural effusion resulting from rupture of a thoracic aneurysm and aortic dissection. An 81-year-old woman had a history of aneurysm for 4 years. Ruptured chronic thoracic aortic dissection was diagnosed in the patient. After 2 weeks of medical therapy, the hematoma in the chest wall was absorbed, the pleural effusion almost disappeared, and the patient’s general condition improved. At 6 months follow-up, the patient had no chest discomfort. This case highlights an uncommon sign of ruptured thoracic aneurysm and aortic dissection that clinicians should be aware of.
