Post-surgical hydropneumopericardium: a case report of dramatic increase in the apparent size of pericardial effusion with positional changes.

ABSTRACT: Background:Pneumopericardium is an uncommon clinical finding. It most commonly occurs after chest trauma but can also emerge as a complication following interventional or surgical procedures and can result in life-threatening complications. A high index of clinical suspicion should be present and once the condition is recognized, it should be managed promptly. Paucity of literature on pneumopericardium makes outlining any new case of paramount importance to emphasize the aspects of diagnosis and management of this rare condition. Case summary:A 59-year-old woman with severe mitral valve and moderate tricuspid valve regurgitation underwent mitral and tricuspid valve repair with uneventful post-operative in-hospital stay. She presented 10?days after discharge with progressive shortness of breath. Chest X-ray revealed right hydropneumothorax. Transthoracic echocardiography (TTE) performed in the emergency department showed an apparently small pericardial effusion with patient in supine position; the effusion size increased substantially when imaging in left lateral decubitus, with presence of intrapericardial air bubbles. Computed tomography scan of the chest confirmed the presence of right hydropneumothorax and hydropneumopericardium, with a communicating pleuro-pericardial tract. The patient underwent chest tube placement which successfully decompressed both pleural and pericardial space. Discussion:Hydropneumopericardium is a rare post-operative complication. Comprehensive TTE with imaging from multiple acoustic windows is mandatory when evaluating the extent of pericardial effusion. Presence of cardiac tamponade is crucial in determining the management plan.

Project description:Background: Primary cardiac angiosarcomas, especially those originating in the pericardium, are extremely rare and aggressive tumors with poor prognosis. These types of malignant tumors have diverse clinical presentations and are often masked by other comorbidities. Case Summary: Our hospital reported a 59-year-old woman who initially presented with pulmonary thromboembolism (PTE) and was subsequently treated with low-molecular-weight heparin. However, she experienced acute pericardial tamponade after anticoagulation therapy, where no obvious mass was primarily identified upon imaging, both in the pericardium or within the heart. Emergency pericardiocentesis and drainage were performed, where a total of 210 mL of bloody effusion was drained. Four months later, she was hospitalized with progressive hemoptysis and dyspnea. A large mixed mass occupying the right pericardium was later identified by coronary computed tomography angiography (CCTA). The mass was consistent with the right atrium, with heterogeneous thickened pericardium and localized moderate pericardial effusion. CCTA and positron emission tomography scans later showed metastases in both lungs and bilateral pleura. Nodules in hilar and mediastinal lymph nodes were also significant. Ultrasound-guided biopsy was performed, and the patient was ultimately diagnosed with an angiosarcoma based on final positive results for both CD31 and CD34 markers. The patient refused chemotherapy and passed away while waiting for her pathology results. The patient survived for 6 months since the first reported episode of PTE. Conclusions: Our case indicates that patients presenting with both embolism and hemorrhage should urgently be channeled to a clinical specialist to confirm any malignant etiology. This would be beneficial to confirm an early diagnosis and lengthen the duration of patient survival. However, the diagnosis of primary cardiac angiosarcoma is still challenging and requires multiple imaging modalities and biopsies in order to assist the accurate diagnosis of disease and achieve effective patient management.
