Abstract:
Despite the low incidence of primary cardiac tumors, recently at our institution, we have experienced two very rare tumors in the span of just a few months. Hibernomas are rare tumors of brown adipose tissue origin that share the benign clinical features of a lipoma, but on imaging mimic the more aggressive sarcoma. Here we present two separate cases of otherwise healthy patients who were found incidentally to have these asymptomatic tumors.
