INTRODUCTION: @entity2293 is a rare manifestation of @entity1375 , and a less rare cause of @entity2294 . The accumulation of the pericardial fluid is gradual, and often does not compromise cardiac hemodynamic function. There is a relationship between the severity and chronicity of the disease with the presence of @entity2294 . There are few cases describing associated pericardial tamponade published in the literature. When a tamponade occurs, a concomitant provocative factor such as a @entity1800 may be related. Our @entity1 's case appears to be the youngest @entity1 described so far. CASE PRESENTATION: We report the case of a previously healthy five-year-old Hispanic (non-indigenous) @entity1 who developed @entity5925 with a history of a recent @entity2294 and tamponade two months before that required the placement of a percutaneous pericardial drainage. @entity2294 was considered to be viral. Later on readmission, clinical primary @entity1375 was diagnosed and thought to be associated with the previous @entity2293 . He developed @entity5925 , which was considered to be autoimmune and was treated with @entity230 . The level of @entity1734 kinase and @entity908 kinase MB fraction returned to within the reference rangeone week after our @entity1 was started on @entity230 and three weeks after he was started on thyroid hormones. CONCLUSIONS: Physicians should consider @entity1375 as a differential diagnosis in @entity1 with @entity2294 . @entity2294 may progress and cause a @entity2293 with @entity1344 . The fact that our @entity1 did not have any manifestations of @entity1375 might have delayed diagnosis.
