An 18F-FDG PET-CT scan incidentally detected increased FDG uptake in the interatrial septum, highlighting the importance of recognizing lipomatous hypertrophy to avoid misdiagnosis of cardiac metastases.

Highlights the potential for incidental detection of benign lipomatous hypertrophy of the interatrial septum on FDG PET/CT imaging.
Clinicians should recognize benign FDG uptake in lipomatous hypertrophy to avoid misinterpretation; case report leaves open prevalence and systematic evaluation.
Lipomatous hypertrophy of the interatrial septum is a benign but less recognized pathology of the heart caused by benign fatty infiltration of the interatrial septum which most often spares the fossa ovalis. We share images of the incidentally detected fluorodeoxyglucose (FDG) uptake in the interatrial septum during the restaging of 18F-FDG positron emission tomography/computed tomography scan of cervical cancer.

Khoo et al. (2018) conducted a case report in Cervical cancer and lipomatous hypertrophy of the interatrial septum (n=1). 18F-FDG PET-CT was evaluated on Incidental finding of lipomatous hypertrophy of the interatrial septum. An 18F-FDG PET-CT scan incidentally detected increased FDG uptake in the interatrial septum, highlighting the importance of recognizing lipomatous hypertrophy to avoid misdiagnosis of cardiac metastases.
