“…MRI examination also shows the cyst contains serous fluid that produces low signal intensity on T1weighted MRI and high signal intensity on T2-weighted MRI. In the present case, the CT number of the mass was higher than that of water (15)(16)(17)(18)(19)(20). We also found that the signal intensity was slightly high on T1-weighted MRI and high on T2-weighted MRI.…”

“…Pericardial cysts occasionally cause complications including erosion into adjacent structures such as the right ventricular wall [12] or the superior vena cava [13], cyst rupture [14], cardiac tamponade [15,16], atrial fibrillation [17], obstruction of the right mainstem bronchus [18], and sudden death [19]. We conclude that our patient may have been at risk of pericardial cyst rupture when she felt chest pain.…”

We report here a case of a patient who underwent surgical resection of a giant pericardial cyst that was growing rapidly, causing anterior chest pain. An asymptomatic 56-year-old woman underwent a complete medical checkup in a health-care center. Her chest X-ray showed an unusually large bulge on the left cardiac border, and she was referred to our hospital. The chest X-ray taken 2 years ago in another hospital showed similar bulge on the same left cardiac border, but it was noticeably smaller. Chest CT revealed a 9.5 × 4.5 cm pericardial cyst within the anterolateral aspect of the left cardiac border. The CT number of the mass was approximately 15 - 20 HU. The mass also showed slight hyperintensity on T1-weighted MR images and hyperintensity on T2-weighted MR images. Four weeks later, she experienced anterior chest pain for the first time, and the chest X-ray and CT showed an increase in the size of the pericardial cyst. The CT number of the mass increased to approximately 30 - 40 HU. The cyst was successfully removed by video-assisted thoracic surgery. The pericardial cyst was diagnosed as benign according to the results of histopathology. We conclude that the rapid growth of the pericardial cyst was caused by intracystic hemorrhage that originated from vascularized connective tissue in the cyst wall

“…15,16 Pericardial cysts usually follow a benign course in the majority of cases, although complications have been reported, which include cyst rupture, erosion of the cyst into adjacent structures, such as the right ventricular wall or superior vena cava, cardiac tamponade, mitral valve prolapse, obstruction of right main stem bronchus, atrial fibrillation, and even sudden death. 14,[17][18][19][20][21][22][23] Considering the complications in nonsurgically treated patients, a conservative treatment approach does not appear to be the best option.…”

“…Under these conditions, an excess of polyamines should be expected to interfere with amoeba differentiation into cysts. Alternatively, their effect on encystation may be related to their toxicity, as observed in other organisms [7,[16][17][18].…”

Stimulation of encystation of Entamoeba invadens by incubation of trophozoites under glucose-limiting conditions brought about a dramatic fall of ornithine decarboxylase activity, a key enzyme in polyamine biosynthesis. Levels of enzyme specific activity after 24 and 48 h of encystation represented only 11% and 1.3%, respectively, of those detected at the start of incubation. Induction of encystation in the presence of exogenously added polyamines resulted in a marked reduction in cyst formation. Thus, after 72 h of incubation, 1.0 mM putrescine, 1.0 mM spermidine or 0.5 mM spermine reduced encystation by 48 to 56%. Inhibition was enhanced to 70-73% in response to a two-fold increase in the concentration of either putrescine or spermine. Our results indicate that polyamine biosynthesis from ornithine is rapidly turned off at the onset of encystation.
