Pleuropericardial cysts are rare, usually benign, often asymptomatic lesions most commonly located in the right cardiophrenic angle and detected incidentally on chest X-ray.
Answers are grounded in this paper and cite their sources.
Supports recognition of pleuropericardial cysts as incidental findings; leaves open prospective data on natural history and thresholds for intervention.
Background: Pleuropericardial cysts (PPCs), account for 5 -10% of all mediastinal tumours, are rare lesions occurring in approximately 1 in 100000 persons and are usually congenital and rarely acquired. They are detected postmortem or incidentally on routine chest X-ray (CXR) and in most cases multi detector Computer Tomography is used to confirm the diagnosis. As benign course and clinical latency are characteristic features of such cysts and the occurrence of complications is rare, the majority of them can be left untreated.
