Cardiac lipoma
Updates to Article Attributes
Cardiac lipomas are uncommon benign primary cardiac neoplasms and occur across a wide age range.
Clinical presentation
They are soft and may grow to a large size without causing symptoms and are usually incidentally discovered. In the pericardial space, they may compress the ventricles or cause shortness of breath by displacing the lungs without affecting left ventricular function.
Pathology
Associations
Cardiac lipomas have been associated with a variety of arrhythmias.
Radiographic features
CT
At CT, cardiac lipomas appear as homogeneous, low-attenuation masses either in a cardiac chamber or in the pericardial.
MRI
Maybe superior to CT in identifying relationship of the lipoma to coronary arteries 4.
At MR imaging, lipomas have homogeneous increased signal intensity on T1-weighted images that decreases with fat-saturated sequences. Cardiac lipomas do not enhance with the administration of contrast material.
Treatment and prognosis
Cardiac lipomas are usually easily resected.
