Abstract
We present the case of a young patient with an apical cardiac mass exhibiting an anterior pseudonecrosis pattern on the electrocardiogram. Cardiac ultrasound revealed a hyperechoic mass infiltrating the apical wall. However, cardiac magnetic resonance ruled out signs of infiltration and demonstrated significant contrast uptake. Vascularization was confirmed through cardiac computed tomography, and 18-fluorodeoxyglucose positron emission tomography showed mild radiotracer uptake. These findings suggested a benign mass despite the presence of significant vascularization. This thorough evaluation enabled the Heart Team to plan and perform a successful surgical excision. The subsequent histologic report demonstrated a cardiac hamartoma.
