A rare case of Pyrexia of Unknown Origin

We present a case of a young male with 3 weeks of fever, evaluated extensively and was found to have a right atrial mass which turned out to be a metastatic deposit from the liver. Intracardiac masses are a rare and unusual cause for Pyrexia of Unknown Origin. The differential diagnoses of intracardiac masses include vegetation, thrombus or tumours. Malignant cardiac tumors are more common than benign tumors. Secondary or metastatic heart tumors occur comparatively more frequently, with an at least 100 times higher incidence than primary tumors of the heart. We present this case in view of its rarity.
