Introduction and importance: We report a rare case of a patient with a mass involving both the hilum and the heart, but its specific nature could not be determined. SCLC was confirmed by postoperative pathology. It revealed that radical surgical resection for T4 SCLC should be considered an important part of multimodality treatment.
Case presentation: A 49-year-old gentleman complained of mild chest tightness for a week. Two large mass lesions were detected on CECT in the left atrium and left hilum. After an MDT discussion, an extended resection was recommended. Postoperative pathology denoted a complete excision with no residuals and negative lymph nodes.
Clinical discussion: Due to the rarity of lung metastases to the heart, it is vital to determine the homology between the hilar mass and the cardiac mass. Based on this, simultaneous surgical treatment is done and it is very beneficial for patients by eliminating those hazards, such as acute mechanical cardiac obstruction, and cardiac embolism. Our literature review demonstrates that the SCLC tumour progresses rapidly after cardiac metastasis, limiting the chance of a complete resection. Furthermore, complete resection of T4 tumours in NSCLC has been attempted many times, so it should also be tried on SCLC.
Conclusion: It is common for SCLC tumours to progress rapidly once they havemetastasized to the heart. An aggressive operation such as radical resection can reduce tumor burdens, minimize the risk of sudden acute death and improve patient follow-up treatment, all of which may prolong the survival of patients.
