Subsequent to the stabilization of the patient’s cardiac condition, meticulous consideration was accorded to the surgical approach to address the thymoma. Given the extensive and aggressive nature of the tumor, evidenced by the imaging results, surgical removal was deemed imperative to mitigate any further compromise to the patient’s health. A comprehensive multidisciplinary review, incorporating oncologic, surgical, and medical perspectives, concurred on the primacy of surgical intervention. The patient underwent a successful surgical resection of the thymoma. Postoperative course was uneventful and the patient was discharged.
