Massive Pericardial Effusion due to Mycoplasma hominis in a Newborn

Focal Bacterial Infections

“…The causes of a pericardial effusion in three fetuses with multiple congenital anomalies, myocardial hypertrophy, and pericarditis are uncertain. Although the inflammatory exudate found at autopsy contained polymorphonuclear leukocytes in addition to lymphocytes, no evidence of bacterial infection was found [521].…”

“…A definitive diagnosis of purulent pericarditis can be made only by obtaining fluid at surgery or through needle aspiration. Care and experience are necessary to facilitate aspiration while avoiding the risks of cardiac puncture or laceration [521]. Accurate monitoring of needle position can usually be obtained through CT guidance, with echocardiographic or fluoroscopic imaging, or by attaching the exploring electrode (V lead) of an electrocardiograph to the needle and by looking for injury current if contact is made with the epicardial surface of the heart.…”

Mycoplasma hominispericarditis in a lung transplant recipient: review of the literature about an uncommon but important cardiothoracic pathogen

“…Including our patient, there have been 4 case reports of isolated M. hominis pericarditis published in the English literature (Table 1) (13,14).…”

Constrictive pericarditis secondary to infection with Mycoplasma pneumoniae

“…Kenney et al [23] report that five of 57 adult patients with large pericardial effusions had positive pericardial fluid or tissue cultures for Mycoplasma species, including two patients with M. pneumoniae, two with M. hominis, and one with Ureaplasma urealyticum. This study also refers to a case of culture-positive M. hominis pericardial effusion in a newborn [24]. The same case was included in Paz and Potasman's [25] review of 21 confirmed cases of Mycoplasma-associated carditis.…”
