Summary
Rare aortic arch aneurysms can mimic mediastinal neoplasms. Multidetector computed tomography is crucial for diagnosing these unusual aortic aneurysms, preventing misdiagnosis as cancer.
Area of Science:
- Cardiovascular Surgery
- Diagnostic Imaging
Background:
- Saccular aortic arch aneurysms can occur in unusual locations.
- These aneurysms may be misdiagnosed as neoplasms preoperatively.
Purpose of the Study:
- To report a case of a rare saccular aortic arch aneurysm.
- To highlight the diagnostic challenges and imaging modalities for such conditions.
Main Methods:
- A 63-year-old male presented with an abnormal mediastinal shadow.
- Computed tomography (CT) scans, including 64-row multi-detector CT, were used for diagnosis.
- Aortic arch replacement was performed via median sternotomy.
Main Results:
- Preoperative imaging suggested a mediastinal neoplasm between the trachea and esophagus.
- Enhanced multi-detector CT confirmed the mass as a saccular aneurysm of the aortic arch.
- Surgical intervention involved aortic arch replacement.
Conclusions:
- Thoracic aortic aneurysms can present as mediastinal neoplasms.
- Multidetector CT is valuable for accurate diagnosis of aortic aneurysms.
- Consider aneurysms when masses are adjacent to the aortic wall.

01:30Aneurysm I: Introduction
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
01:26Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
01:22Mitral Stenosis I: Introduction
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
01:15Aortic Regurgitation I: Introduction
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
