Natural History and Sequelae of Penetrating Aortic Ulcer
A man in his 70s with history of tobacco use and hypertension presented for transesophageal echocardiography after a recent diagnosis of ischemic stroke. This demonstrated a moderate right-to-left shunt on Valsalva release and no left atrial appendage thrombus. Assessment of the thoracic aorta revealed a complex penetrating aortic ulcer and saccular aneurysm with thrombus in the distal arch and proximal descending thoracic aorta (Figure). Computed tomography angiography confirmed the presence of multiple penetrating ulcerations with large saccular aneurysms.

54-Year-Old Woman With Altered Mental Status and Abdominal Pain
A 54-year-old woman was transferred to our medical center with altered mental status, abdominal pain, and hypotension. Her medical history included type 2 diabetes mellitus, hypertension, hyperlipidemia, active tobacco use, prior cholecystectomy, and a recent stroke. One month earlier, she presented to an outside facility with right-sided facial weakness and numbness. Brain magnetic resonance imaging (MRI) at that time revealed multiple small lacunar-type infarcts. Computed tomography (CT) angiography of the head and neck, 48-hour Holter monitoring, and transesophageal echocardiography did not reveal an embolic source.

Craniocervical Artery Dissections: A Concise Review for Clinicians
Craniocervical artery dissection (CAD), although uncommon, can affect the young and lead to devastating complications, including stroke and subarachnoid hemorrhage. It starts with a tear in the intima of a vessel with subsequent formation of an intramural hematoma. Most CAD occurs spontaneously or after minor trauma. Patients with CAD may exhibit isolated symptoms of an underlying subclinical connective tissue disorder or have a clinically diagnosed connective tissue disorder. Emergent evaluation and computed tomography angiography or magnetic resonance imaging/angiography of the head and neck are required to screen for and to diagnose CAD.
