Imaging primary cardiac angiosarcoma: case-based illustrations with multimodality imaging and emphasis on the role of...

Primary cardiac angiosarcomas are extremely rare, highly aggressive tumours with rapid progression and high metastatic capability. More than 60% of tumours are detected after the onset of a metastatic disease. In the two cases presented, we demonstrate the role of muti-modality imaging in the diagnosis of the lesion and provide valuable input in prognosticating the disease burden. In both cases, the diagnosis was suspected initially by imaging, based on radiological observations, before the final histopathology confirmation was made. Positron emission tomography- (PET-CT) was a critical component of the diagnostic workup for the detection of disease extent and volume of total disease burden. Hence, PET-CT imaging should be performed in all aggressive appearing cardiac tumours. In view of misleading clinical presentation, we suggest that aggressive workup to be performed in suspected patients. Young patients presenting with vague symptoms and those with recurrent, unresolving, unexplained pericardial effusion deserves special consideration.
