1/11. Cardiac metastasis of hepatocellular carcinoma mimicking pericardial effusion on radionuclide angiocardiography.A 51-year-old man presented with exertional dyspnea for two months. He had a history of hepatocellular carcinoma that was totally resected three years earlier. Radionuclide angiocardiography disclosed a large photopenic area separating the heart from the liver, and lung blood pools mimicking a large pericardial effusion. echocardiography and magnetic resonance imaging of the heart, however, showed extensive tumor infiltration of the myocardium of both ventricles. Endomyocardial biopsy confirmed the diagnosis of metastatic hepatocellular carcinoma. There was no evidence of recurrent hepatoma in the liver.- - - - - - - - - - ranking = 1keywords = radionuclide (Clic here for more details about this article) |
2/11. Hepatic hydropericardium.A 41-year-old man with chronic hepatitis c and cirrhosis presented with pericardial effusion and tamponade requiring pericardiocentesis. Nine liters of pericardial fluid was drained with complete resolution of his ascites. He represented with recurrent pericardial effusions despite salt restriction and diuretic therapy. Subsequent radionuclide scans demonstrated a direct connection between the peritoneal and pericardial spaces. A pericardial window was formed but despite this there was recurrence of pericardial effusion and pleural effusion. The patient underwent orthotopic liver transplantation 7 months later and no recurrence of pleural or pericardial effusion was observed following transplantation. We believe this is the first case report of pericardial effusion secondary to cirrhotic ascites and a communication between the peritoneal and pericardial cavities.- - - - - - - - - - ranking = 0.25keywords = radionuclide (Clic here for more details about this article) |
3/11. pericardial effusion following conditioning for bone marrow transplantation in acute leukaemia.We report the details of a young woman in whom pericardial tamponade developed acutely following preparation for allogeneic bone marrow transplantation for acute lymphoblastic leukaemia. The aetiology of the effusion, though uncertain, probably relates to the cumulative cardiotoxicity of cyclophosphamide and irradiation upon a myocardium previously sensitised by anthracycline therapy. As the number of transplant procedures increases, this complication may become more common, and might be avoided by a more critical assessment of cardiac function prior to transplantation, with radionuclide angiography.- - - - - - - - - - ranking = 0.25keywords = radionuclide (Clic here for more details about this article) |
4/11. diagnosis of malignant pericardial effusion during dynamic hepatic scintigraphy.Three clinically unsuspected malignant pericardial effusions were discovered during routine dynamic hepatic scintigraphy. The only common clinical feature shared by the patients was dyspnea. Static scintigrams alone would not have detected these effusions, which points out again the importance of including dynamic scintigraphy in routine radionuclide evaluations of the liver.- - - - - - - - - - ranking = 0.25keywords = radionuclide (Clic here for more details about this article) |
5/11. Two cases of primary isolated chylopericardium diagnosed by oral administration of 131I-triolein.Two cases of isolated chylopericardium, one idiopathic and the other secondary to the lymphangioma of the pericardium are reported here. In both cases, correct diagnosis was made by radionuclide imaging techniques. When imaging the cardiac pool using 99mTc-in vivo, labeled RBC, a large separation between the heart and surrounding organs was demonstrated; this suggested a presence of massive pericardial effusion. On pericardial imaging taken 24 hours after oral administration of 131I-triolein, a donut-like shape was clearly produced, situated in a gap between the separation, suggesting chylous effusion within the pericardial space. On operating, isolated chylopericardium was confirmed in both cases. To our knowledge, this is the first report of preoperative noninvasive diagnosis of chylopericardium in japan.- - - - - - - - - - ranking = 0.25keywords = radionuclide (Clic here for more details about this article) |
6/11. Chylopericardium: a rare cause of pericardial effusion.A 21 year old man presented with asymptomatic, isolated chylopericardium. Despite echocardiography, radionuclide-angiography, computer tomography, and chemical analysis of the chylous effusion, the etiology remained obscure. After patent blue dye infusion into peripheral soft tissues, the appearance of coloring material in the effusion at 4 hours suggested direct communication of the pericardium with an apparently large thoracic duct. Fifteen months later, cardiomegaly persists in site of medium-chain triglyceride dietary restriction.- - - - - - - - - - ranking = 0.25keywords = radionuclide (Clic here for more details about this article) |
7/11. Radionuclide ventriculographic findings in pericardial effusion.We present a patient with a large pericardial effusion, in whom the first-pass radionuclide ventriculogram demonstrated rocking motion of the left ventricle and apparent asynergy of the inferior wall. These abnormalities disappeared after removal of the fluid. Inspection of the cinematic display of the images was useful in explaining the apparent asynergy of the inferior wall.- - - - - - - - - - ranking = 0.25keywords = radionuclide (Clic here for more details about this article) |
8/11. Varying ejection fractions of both ventricles in paradoxical pulses: demonstration by radionuclide study.A noninvasive radionuclide study of the paradoxical pulse in pericardial effusion is described. The study shows complementary changes of the right and left ventricular ejection fractions in a patient with paradoxical pulse, supporting the theory that the inspiratory reduction of the left ventricular stroke volume is an immediate and direct result of the inspiratory increase of the right ventricular filling. The technique may be sensitive to detect early paradoxical pulse and cardiac tamponade.- - - - - - - - - - ranking = 1.25keywords = radionuclide (Clic here for more details about this article) |
9/11. Peritoneopericardial communication after pericardiocentesis in a patient on continuous ambulatory peritoneal dialysis with dialysis pericarditis.A male patient aged 41 years had dialysis pericarditis with massive pericardial effusion in his 6-year on continuous ambulatory peritoneal dialysis (CAPD). Intensive hemodialysis failed to resolve the pericardial effusion. pericardiocentesis via a subxiphoid approach was performed with placement of a pigtail catheter for drainage. A communication between peritoneal and pericardial cavities occurred, resulting in the leakage of the peritoneal dialysate into pericardial sac which was confirmed by a 99mTc radionuclide scan. The fistula healed after removal of the catheter and discontinuation of CAPD. We suggest that pericardiocentesis via a subxiphoid approach for pericardial effusion should be cautiously exercised in CAPD cases for fear of peritoneopericardial fistula.- - - - - - - - - - ranking = 0.25keywords = radionuclide (Clic here for more details about this article) |
10/11. Severe right ventricular contraction asynchronism revealing a large pericardial effusion.A gated blood-pool equilibrium radionuclide angiography was performed in a patient to determine the ejection fraction for doxorubicin cardiotoxicity evaluation. The phase image of the first harmonic of the fourier analysis revealed a severe delay of the right ventricular contraction compared with that of the left ventricle. This right ventricular contraction asynchronism was due to a large pericardial effusion, confirmed by the presence of the halo sign on the summed gated images and by echocardiography. The phase delay moves towards normalization after pericardiocentesis. Although radionuclide angiocardiography is not the best method for identification of pericardial effusion, this diagnosis should be evoked when a severe homogenous delay of the right ventricular contraction is observed.- - - - - - - - - - ranking = 0.5keywords = radionuclide (Clic here for more details about this article) |
