Primary pericardial tumours are very rare and are hence not usually part of our differential diagnosis, especially since they have non-specific signs and symptoms. While chest radiography remains the most common initial imaging investigation in the assessment of suspected cardiothoracic pathology, the diagnostic yield for assessing pericardial lesions is limited, often necessitating the need for further assessment with echocardiography, CT scan or MRI. We present a case of an adult male patient with an incidental primary pericardial tumour diagnosed during the routine imaging assessment of suspected pulmonary infections. After proper formulation of diagnosis, the patient was managed accordingly for pulmonary pathology and discharged on recovery. Over the years, with advancement and widespread increase in use of multidetector CT and MRI, diagnosing primary pericardial tumours has become easier. MRI has now become the modality of choice for imaging of pericardial tumours because of its better soft-tissue contrast resolution.
