Case study reveals limitations of multimodality imaging in diagnosing myxoma vs. thrombus in transplant patients, suggesting caution in interpretation.
We present a case of left atrial thrombus mimicking myxoma after orthotopic heart transplantation. Multimodality imaging established the diagnosis of atrial myxoma, and the patient was treated accordingly, but the definite diagnosis after surgical excision and histology showed left atrial thrombus. This report demonstrates the limitations of multimodality diagnosis in tumors with features highly suggestive of an atrial myxoma.
