Key result
A 14.9 mm lipomatous hypertrophy of the interatrial septum was incidentally diagnosed via computed tomography and echocardiography in a 56-year-old woman treated for a gastrointestinal bleed.
Why the study?
Lipomatous hypertrophy of the interatrial septum is a benign lesion that previously has not been readily described, but is becoming a more well-characterized incidental finding with increasing imaging usage.
Case Report (n=1)
This case highlights that lipomatous hypertrophy of the interatrial septum can be incidentally and definitively diagnosed using non-invasive multimodality imaging like CT and echocardiography, avoiding the need for biopsy.
Recognizing incidental LHIS avoids unnecessary intervention; single case leaves open need for systematic characterization.
Lipomatous hypertrophy of the interatrial septum (LHIS) is a benign non-neoplastic cardiac lesion that previously has not been readily described, but with the increasing usage of computed tomography and echocardiography, this is now becoming a more well-characterized incidental finding. This case highlights an incidental finding of LHIS while a patient was undergoing treatment for a routine gastrointestinal bleed.

Rose et al. (2023) conducted a case report in Lipomatous hypertrophy of the interatrial septum (n=1). Computed tomography and transthoracic echocardiography was evaluated on Diagnosis of lipomatous hypertrophy of the interatrial septum. A 14.9 mm lipomatous hypertrophy of the interatrial septum was incidentally diagnosed via computed tomography and echocardiography in a 56-year-old woman treated for a gastrointestinal bleed.
