18F-FDG PET/CT can incidentally detect metabolic evidence of right ventricular strain in patients with malignancy-associated pulmonary hypertension.
Right ventricular (RV) myocardial strain is a rare inflammatory response that occurs in response to acute RV pressure overload, often as a result of pulmonary hypertension (PH). We present a case involving a 65-year-old male with a small cell Pancoast tumor causing obstruction of the right upper pulmonary artery, resulting in PH and RV dilation. 18 F-Fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) revealed diffuse uptake of FDG in the RV myocardium, indicating RV myocardial strain. Echocardiography confirmed signs of PH, including significant RV dilation and strain patterns. This case highlights the importance of recognizing RV myocardial strain as an incidental but crucial finding on 18 F-FDG PET/CT, especially in cases of malignancy-associated PH.
Goyal et al. (Sat,) conducted a case report in Small cell Pancoast tumor with pulmonary hypertension and right ventricular strain (n=1). 18F-FDG PET/CT was evaluated on Detection of right ventricular myocardial strain. 18F-FDG PET/CT incidentally detected right ventricular myocardial strain secondary to tumor-induced pulmonary artery obstruction in a patient with a small cell Pancoast tumor.
