Cardiac Neurilemmoma, Rat

摘要: This neoplasm is often an incidental finding at necropsy and in its early stages may not be grossly evident even when the heart cut to reveal interiors of chambers. The lesion consists a firm, white gray coating over all or part lining one chamber, most left ventricle. More advanced tumors are as firm , grayish-white masses that partially fill more chambers diffusely invade myocardium. Rarely, tumor grow through myocardium expand exophytic mass on external surface heart. Infiltrative growth then extend along major blood vessels within beyond mediastinal cavity involve lungs soft tissues neck head, some exceptional cases extending far orbit. Photographs illustrating both lesions have been published (Ivankovic 1976).
