Key result
68Ga-DOTATATE PET/CT and cardiac MRI successfully detected isolated myocardial metastases at initial staging in a patient with a well-differentiated neuroendocrine tumor.
Why the study?
Cardiac metastases from neuroendocrine tumors are rare and typically occur in advanced metastatic disease.

May prompt complementary CMR for myocardial uptake on 68Ga-DOTATATE PET/CT in neuroendocrine tumors; hypothesis-generating for rare isolated myocardial metastases.
Cardiac metastases from neuroendocrine tumors (NETs) are rare and usually occur in advanced metastatic disease. We present a 58-year-old man with a well-differentiated terminal ileum NET (grade 1, Ki-67 1%) who underwent 68Ga-DOTATATE PET/CT for staging. The scan demonstrated intense uptake in the primary tumor and 2 incidental myocardial foci. Subsequent cardiac magnetic resonance imaging (CMR) revealed myocardial signal heterogeneity at corresponding locations, supporting the diagnosis of myocardial metastases. This case illustrates isolated myocardial involvement detected at initial staging of a well-differentiated NET and highlights the complementary role of somatostatin receptor-based PET/CT and CMR in detecting cardiac metastases.

Baltacioglu et al. (2026) conducted a case report in Neuroendocrine tumor with myocardial metastases (n=1). 68Ga-DOTATATE PET/CT and CMR was evaluated on Detection of myocardial metastases. 68Ga-DOTATATE PET/CT and cardiac MRI successfully detected isolated myocardial metastases at initial staging in a patient with a well-differentiated neuroendocrine tumor.
