Left Common Carotid Artery Agenesis With Independent Origins of the External and Internal Carotid Arteries From the Aortic Arch: A Rare Case in a Patient With Ankylosing Spondylitis.

The agenesis of the left common carotid artery, with independent origins of the external and internal carotid arteries from the aortic arch, is a well-described but extremely rare congenital anomaly. We present a case of agenesis of the left common carotid artery with the independent origin of the left internal and left external arteries from the arch of the aorta in a patient with ankylosing spondylitis which was depicted by CT angiogram and magnetic resonance angiography. The diagnosis of this anatomical variant especially before interventional procedures is of great importance, as it could complicate the catheterization of these arteries.

Spontaneous Splenic Rupture in Malaria Patients: Two Case Reports.

Atraumatic splenic rupture is a rare and life-threatening condition, if not diagnosed. We present two cases with a history of travel to endemic areas, who came to the emergency department with abdominal pain and were diagnosed to have spontaneous splenic rupture as a complication of severe malaria. Both patients were treated surgically by splenectomy. A high level of clinical suspicion is critical in every malaria patient presenting with abdominal pain, even if it is mild. Clinical imaging modalities like ultrasonography and computed tomography (CT) are crucial diagnostic tools in managing such patients.
