Recurrence of a Thymic Carcinoid Tumour 15 Years After Resection With Multiple Myopericardial Cardiac Metastases: The Role of Multimodality Imaging

Abstract

Carcinoid tumours arising from the thymus are exceedingly rare, and cardiac metastases have not previously been described in the setting of a primary thymic carcinoid tumour. We present a patient with recurrence of a carcinoid tumour initially resected from the thymus 15 years earlier, with multiple cardiac metastases. These metastatic tumours were visualized using multiple imaging modalities, including computed tomography, transthoracic echocardiogram, magnetic resonance imaging, and octreotide scan. A subsequent biopsy confirmed recurrence of his carcinoid tumour. This case highlights the role of multimodality imaging for diagnosis and the need for continued long-term surveillance in these patients.
