To date, there have only been a few reports highlighting the incidence of these atrial tachycardias due to mechanical compression of myocardial structures and the pulmonary vasculature in certain mediastinal masses and cysts. CASE: We present a case of a 75-year-old gentleman who is a nonsmoker with a history of hypertension who presents with an acute embolic stroke due to atrial flutter likely from mechanical compression from an underlying squamous cell carcinoma of the lung. CONCLUSION: This case represents, to the best of our knowledge, a rare case of squamous cell carcinoma of the lung in a nonsmoker likely leading to mechanical compression and a resultant atrial tachycardia with an embolic stroke.en-USatrial flutterembolic strokesquamous cell lung carcinomaCritical CareNeoplasmsRadiologyJournal Articlehttps://escholarship.umassmed.edu/radiology_pubs/21210133377radiology_pubs/212
