AI Article Synopsis
- Lipomatous hypertrophy of the interatrial septum (LHIS) is a rare and benign condition where fat accumulates in the heart's atrial septum, often forming a distinct hourglass shape while leaving a specific area (fossa ovalis) unaffected.
- A case study highlighted the unique features of LHIS using cardiac magnetic resonance (CMR), showing unusual characteristics and no uptake of 18F-FDG in PET-CT scans, which differs from prior reports.
- This finding suggests that CMR and PET imaging can help differentiate LHIS from more serious conditions like lipomatous tumors, potentially reducing the need for unnecessary surgeries.
Article Abstract
Lipomatous hypertrophy of the interatrial septum (LHIS) is a rare benign heart disease characterized by excessive deposition of adipose tissue in the atrial septum with sparing fossa ovalis, which demonstrates a characteristic hourglass/dumbbell configuration. We reported a case of LHIS with inhomogenous characteristic on CMR and persistently no FDG uptake on 18F-FDG PET-CT, which is contrary to a few previous cases. This single case report suggests that in case LHIS present in-homogenous characteristic on CMR, metabolic PET imaging could be used as a complementary imaging model to decrease the concern of lipomatous neoplasms, thereby avoid unnecessary surgical therapy.

Even if rarely detected, right atrial (RA) masses represent a diagnostic challenge due to their heterogeneous presentation. Para-physiological RA structures, such as a prominent Eustachian valve, Chiari's network, and lipomatous atrial hypertrophy, may easily be misinterpreted as pathological RA masses, including thrombi, myxomas, and vegetations. Each pathological mass should always be correlated with adequate clinical, anamnestic, and laboratory data.

Article Synopsis
- Primary cardiac tumors (PCTs) like myxomas and lipomas are rare, with lipomas being soft fat masses that can lead to diagnostic challenges.
- Lipomatous hypertrophy of the atrial septum (LHAS) is a benign condition linked to aging and obesity, distinct from true cardiac lipomas.
- A case of a true atrial septal lipoma discovered during heart dissection is detailed, highlighting its potential effects on heart function and contributing to the scarce literature on benign primary cardiac tumors.

Platypnea-orthodeoxia syndrome (POS) is characterized by dyspnea due to a marked fall in blood oxygen saturation while assuming standing or sitting positions. It is a rare condition with an unknown prevalence. The triggering role may remain unclear in a considerable number of patients.
