1 maj 2021 · Lipomatous hypertrophy of the interatrial septum (LHIAS) is a benign accumulation of adipose tissue within the interatrial septum, though it can sometimes be mistaken for neoplasm. Multimodality imaging can help differentiate this entity from other cardiac lesions, as illustrated in this case.
28 lip 2018 · Lipomatous hypertrophy of the atrial septum (LHAS) is an anomaly of the heart. It is characterized by an infiltration of adipocytes into myocytes of the interatrial septum, sparing the fossa ovalis, which gives a characteristic hourglass-shaped image.
Lipomatous hypertrophy of atrial septum (LHAS) is a rare benign cardiac condition characterized by fatty tissue infiltration located in the atrial septum. We presented a rare case of LHAS resulting in recurrent syncopal attacks.
Lipomatous hypertrophy of the interatrial septum (LASH) is a benign lesion characterized by massive accumulation of fat in the interatrial septum that exceeds 2 cm in thickness and is part of the differential diagnosis for malignant and benign atrial tumors.
On 3D transesophageal echocardiogram (TEE) the mass appeared to be a lipomatous hypertrophy of the septum without apparent thrombus. Pathology reports of the specimen were notable for an organized clot with mild mixed inflammation, contradicting the TEE findings.
27 sie 2024 · Lipomatous hypertrophy of the interatrial septum (LHIS) is a rare but benign cardiac tumor that can be found on cardiac imaging such as echocardiogram, or during surgery or an autopsy. Cardiac MRI is the best imaging modality to determine the borders of the tumor and its extension into the intravent ….
LHIS has also been described in patients receiving long-term parenteral nutrition (9). Clinically, LHIS has been associated with atrial arrhythmias. The infiltrated septum may play a central role as an both ectopic source and a zone of re-entry, with autonomic tone being a key regulator.
