Aortic Dissection Masquerading as Pneumonia: A Case Report of an Atypical Presentation.

Aortic dissection is a critical and life-threatening condition that can present with atypical symptoms, often leading to misdiagnosis and delayed treatment. The report presents a case of a 65-year-old male who initially exhibited fever, right-sided chest pain, and a productive cough, resulting in an initial diagnosis of pneumonia. Despite empirical antibiotic therapy, his symptoms persisted, prompting further investigation. A computed tomography (CT) scan ultimately revealed a Type B aortic dissection. The patient was then transferred to a specialized tertiary care facility for successful endovascular intervention. This case underscores the importance of considering aortic dissection in patients presenting with persistent, atypical symptoms that do not respond to standard treatments, such as unexplained fever and chest pain. It highlights the crucial role of advanced imaging techniques, such as CT scans, in achieving an accurate and timely diagnosis. Clinicians must maintain a high index of suspicion and ensure prompt referral to specialized centers to improve patient outcomes in this potentially fatal condition.
