title: The role of echocardiography in diagnosis and management of isolated meningococcal pericarditis.
abstract: Although pericarditis may complicate the course of meningococcemia, it is distinctly unusual as a presenting sign. Herein we report a case of a previously healthy 16-year-old male with isolated meningococcal pericarditis, in which transthoracic echocardiography was of great importance for the initial diagnosis and for guiding the therapeutic approach during the hospitalization period. The patient presented with symptoms of chest pain and fever that deteriorated into cardiac tamponade. Pericardiocentesis was successful and Neisseria meningitidis was identified as the causative agent in the pericardial fluid. Because of failure of clinical resolution, echocardiogram was repeated and showed evidence of maintenance of large echo dense content in pericardial space. The presence of purulent content was confirmed during open-chest surgery. The role of echocardiography for the correct management of this rare form of pericarditis is discussed.
