Idiopathic right atrial enlargement is a rare cardiac anomaly presenting as a giant right atrium. A 20-year-old woman presenting for pneumothorax was found to have a pericardial mass compressing right ventricle. Echocardiography and magnetic resonance suggested the diagnosis of lone right atrial appendance enlargement. The mass was surgically removed and histopathology confirmed the diagnosis of right atrial appendance aneurysm. The case is notable for its rarity.
The present report describes the case of a 55-year-old woman who suffered from cardio-embolic stroke originating from malignant fibrous histiocytoma (MFH) localized on the mitral valve. The patient underwent transthoracic two-/three-dimensional and transoesophageal echocardiography which demonstrated the mass protruding in the outflow tract of the left ventricle. Differential diagnosis had to be made with other masses in the left ventricle, such as thrombi, vegetations, and cardiac tumours. Surgery was performed to remove the tumour and the surgery findings confirmed echocardiographic images. Primary cardiac tumours are a rare entity, and their incidence is approximately 0.0017-0.019%. The majority of them are benign, but in a quarter of cases they are malignant. This case is an example of an MFH which caused embolism to the central nervous system.
Thoracoscopic sympathecotomy clamping is a successful treatment for hyperhidrosis. Local hyperhydrosis does not reoccur after 17 months, but there is some degree of compensatory hyperhidrosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
