Key result
Multimodality imaging diagnoses lipomatous hypertrophy of the interventricular septum to guide conservative management.
Why the study?
Primary cardiac tumors are rare, and lipomatous hypertrophy of the interventricular septum is a rarely reported benign cardiac condition.
Case Report (n=1)
Cardiac magnetic resonance imaging is a valuable tool for differentiating rare benign cardiac tumors like lipomatous hypertrophy of the interventricular septum from cardiac lipomas, guiding appropriate conservative management.
Supports conservative management in confirmed adolescent cases; leaves open need for longitudinal data on natural history.
Primary cardiac tumors are rare. We report a case of lipomatous hypertrophy of the interventricular septum in a healthy, asymptomatic, 16 year old female, diagnosed initially by echocardiogram. Non contrast Computed tomography (CT) and Cardiac magnetic resonance imaging (CMR) were also performed to confirm the diagnosis of this rarely reported condition. Lipomatous hypertrophy of the interventricular septum is a rare form of benign cardiac tumor characterized by the proliferation of adipose tissue (fat) in the interventricular septum. This clinical entity has to be differentiated from cardiac lipoma which is a benign, encapsulated tumor. CMR helps is differentiating between the 2 conditions. As the lesion was neither causing compression of the ventricle nor obstruction to blood flow, she was managed conservatively and advised follow up.

Subbaraman et al. (2021) conducted a case report in Lipomatous hypertrophy of the interventricular septum (n=1). Conservative management was evaluated. Conservative management was advised for a 16-year-old female diagnosed with lipomatous hypertrophy of the interventricular septum via echocardiogram, CT, and CMR.
