We present the case of a 38-year-old Malay man with progressive dyspnea and palpable purpura in his lower limbs. The diagnostic evaluation revealed right-sided segmental pulmonary consolidation with pleural effusion, systolic cardiac dysfunction with the presence of an intracardiac thrombus, and left vocal cord palsy secondary to laryngeal mononeuropathy.
