1/18. Intracardiac juvenile xanthogranuloma in a newborn.Juvenile xanthogranuloma (JXG) presents a normolipemic non-langerhans cells histiocytosis. JXG usually presents with cutaneous lesions. Visceral involvement is rare but may affect various organs. Deep JXG differs histologically from the cutaneous form by its tendency to consist solely of homogeneous proliferation of histiocytes without any xanthomatous or Touton giant cells. awareness of the possibility of this atypical presentation of JXG helps in making the correct histologic diagnosis, which is supported by proving adequate immunomarkers on histiocytes (mainly PG-M1, an antibody against the CD68 antigen). JXG may present with intramuscular lesions only; however, rarely JXG has been reported to affect the heart but not without the typical cutaneous manifestations. We present an unusual case of deep JXG without systemic disease or metabolic abnormalities. To our knowledge, this is a first reported case of intracavitar JXG without skin lesions.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/18. T-wave alternans associated with heart failure and hypomagnesemia in alcoholic cardiomyopathy.Marked T wave abnormality developed in a patient with alcoholic cardiomyopathy. The T negativity was of giant size and occurred in an alternating sequence in the presence of sinus rhythm. This change was rapidly transient, disappearing in 3 days. The complete electrocardiographic recovery was temporally related to successful treatment of severe heart failure, normalization of initially low serum magnesium level, and abolition of recurrent ventricular fibrillation.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
3/18. Displacement of the heart by a giant mediastinal cyst.A giant mediastinal cyst caused marked cardiac displacement, factitious cardiomegaly and clinical and hemodynamic findings suggestive of constrictive pericarditis. The correct diagnosis was established with echocardiography and confirmed with angiography and surgery.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
4/18. Solitary pericardial hydatid cyst.Hydatid cyst of the heart is an uncommon presentation of human echinococcosis which may lead to life-threatening conditions. diagnosis should be suspected in every case of cyst-like mass in persons coming from areas where echinococcus granulosus is endemic. echocardiography, computed tomography and magnetic resonance imaging can help in the differential diagnosis of the lesion. Even if some reports of successful therapy with benzimidazoles have been described, the treatment of choice is the surgical excision of the cyst. pericardiectomy with cyst removal is feasible with low morbidity and mortality rates even in elder patients. The authors describe the successful surgical management of a single giant pericardial hydatid cyst in a 78-year-old woman from North africa.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
5/18. Acute respiratory insufficiency and giant coronary artery aneurysm with fistula.Several causes of acute respiratory insufficiency have been reported in the literature. We describe a case in which it was caused by a rare combination of a giant right coronary artery aneurysm with fistula that occurred in a 56-year-old woman with concomitant congenital hypothyroidism. Diagnostic tools, differential diagnosis, surgical techniques, and follow-up at 1 year are discussed.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
6/18. rupture of a giant coronary artery aneurysm due to Kawasaki disease.Coronary artery aneurysm requiring surgery is rare. We report a case of a ruptured giant coronary artery aneurysm due to Kawasaki vasculitis which presented with cardiac arrest and was successfully treated by emergency coronary artery bypass grafting. The controversies surrounding the management of this disease are also discussed.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
7/18. mitral valve replacement in a patient with a collapsed lung and a giant abscess.mitral valve replacement was performed on a 75-year-old man with a history of pulmonary tuberculosis. Computed tomography showed a collapsed left lung and counterclockwise rotation of the heart due to a hard abscess. Surgery was performed through a median sternotomy, and extensive pericardial suspension was useful for obtaining an adequate view. Despite poor pulmonary function, the patient was extubated on the day of surgery and had an uneventful postoperative course. Cardiac surgery can be performed in patients with a single functional lung if their preoperative respiratory function is good enough to have daily life without dyspnea.- - - - - - - - - - ranking = 4keywords = giant (Clic here for more details about this article) |
8/18. Dynamic electrocardiographic changes due to cardiac compression by a giant hiatal hernia.A 79-year-old woman was admitted due to chest pain with T wave inversion and anasarca. echocardiography demonstrated a mass compressing the heart and computed tomography revealed a giant hiatal hernia within the intrathoracic stomach located just behind the heart. After drainage of the gastric contents, the T wave inversion disappeared, but subsequent ST elevation in leads V1-V6 was noted. After surgical correction of the hiatal hernia, the ST segment elevation returned to a nearly normal level. The changes in the compressed heart induced by hiatal hernia may cause pericarditis resulting in electrocardiographic changes.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
9/18. A giant thrombus in the right ventricle of a newborn with down syndrome: successful treatment with rt-PA.An association between thromboembolic events and down syndrome (DS) has been increasingly reported in the literature. It is not clear whether patients with DS have increased risk for thrombotic disorders or there is a coincidence. We present a case of giant right ventricular thrombus in a neonate with DS. risk factors for thrombosis in the present case were neonatal sepsis and dehydration. There was no congenital heart anomaly. The patient was treated successfully using recombinant tissue plasminogen activator. Recombinant tissue plasminogen activator seems to be a safe and effective thrombolytic therapy in neonates.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
10/18. Giant gastric ulcer penetrating into the heart as a late complication of Nissen fundoplication. Case report.A case of fatal hemorrhage from a fistula penetrating into the right ventricle is reported. The source of the bleeding was a giant ulcer on a Nissen fundoplication performed 5 years previously to relieve gastroesophageal reflux. The pathologic sequence does not seem to have been previously described.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
