Summary
A rare case of adenocarcinoma presenting as an aortic thrombus was identified in a 69-year-old man. This emphasizes the need for careful diagnosis in unusual medical presentations.
Area of Science:
- Cardiovascular Surgery
- Oncology
- Diagnostic Imaging
Background:
- A 69-year-old male presented with acute back pain.
- Computed tomography (CT) and magnetic resonance imaging (MRI) revealed a floating mass in the descending aorta, initially suspected to be a thrombus.
Observation:
- The mass, attached by a stalk to the aortic wall, mimicked a thrombus on imaging.
- Surgical resection was performed under extracorporeal circulation, followed by stent graft placement.
Findings:
- Pathological examination unexpectedly diagnosed the mass as adenocarcinoma.
- The primary source of the malignancy remained undetected despite further investigations.
Implications:
- This case highlights the diagnostic challenges posed by rare aortic tumors mimicking thrombi.
- Accurate preoperative diagnosis is crucial for appropriate management and patient outcomes in rare cardiovascular and oncological conditions.
