Esophago-pericardial fistula is a rare, life-threatening condition, usually arising as a complication of benign esophageal disorders or iatrogenic causes. Prompt diagnosis via multimodality imaging is crucial, with computed tomography being the most sensitive. Management varies based on severity, with a growing trend toward early endoscopic interventions, which result in improved outcomes.

Hydropneumopericardium is a rare event with a risk of serious complications. Timely diagnosis and treatment is important as it can improve prognosis. We report the case of a 77-year-old male patient who presented with acute interscapular pain which developed during a meal. An oesophago-pericardial fistula was found in the context of malignant oesophageal disease.
CONCLUSIONS: Hydropneumopericardium secondary to oesophageal tumour is a rare but life-threatening finding that has a very poor prognosis.A high level of suspicion is needed, as the clinical manifestations are very unspecific and timely treatment can improve prognosis.Successful management of an oesophago-pericardial fistula includes surgical treatment and antibiotic therapy.

Gastropericardial fistula is a rare but lethal condition. Several etiologies have been reported, including previous gastric or esophageal surgery, malignancy, trauma, infection, and ulcer perforation. Typical symptoms included chest pain, epigastric pain, fever and dyspnea. Gastropericardial fistula can lead to serious complications, including cardiac tamponade, sepsis, hemodynamic compromise and death. Therefore, early diagnosis and timely management are important for physicians to prevent from catastrophic complications. Here, we present a case of a man who presented with acute purulent pericarditis secondary to a gastropericardial fistula to highlight the pathogenesis and suggest therapeutic strategies.

Gastropericardial fistula, a rare condition characterized by an abnormal communication between the stomach and the pericardium, is an emergency as sequelae such as cardiac tamponade and sepsis may lead to hemodynamic instability and death. We aimed to summarize the surgical and radiologic findings of the reported cases published to date, describe their pertinent surgical history, and present an algorithm for diagnosis.
The Pubmed database was searched using the terms: gastropericardial, pericardiogastric, pneumopericardium, pericardial, and pneumopericardium with the term \"fistula\" added to each term. The search was limited to January 2000-October 2015 and English language publications.
Thirty five cases were identified. The most common etiology was prior esophageal and/or gastric surgery (80% of cases; esophagectomy = 26%/gastrointestinal reflux disease associated surgery = 23%/bariatric surgery = 11%/partial gastrectomy = 6%/other = 20%). The average duration between presentation and surgery was 7.3 ± 6.2 years (SD). Radiology typically played a crucial role in diagnosis with computed tomography most commonly demonstrated to be the most appropriate modality to demonstrate the fistula and assist in surgical planning. Contrast studies were frequently helpful to confirm the diagnosis. Chest x-ray findings including pneumopericardium and pericardial thickening were contributory but nonspecific. Esophagoduodenoscopy characterized the fistula in cases where imaging was equivocal and may provide therapeutic options.
We present the clinical radiologic findings of the 35 cases of gastropericardial fistula reported. This is the first literature review of gastropericardial fistula to focus on the effectiveness of these various diagnostic modalities and to present an algorithm for diagnosis.
