A 4-year-old castrated labrador retriever presented for cardiac evaluation to determine the etiology of cardiogenic pulmonary edema diagnosed 1 month prior. A large pedunculated mass involving the ventral aspect of the mural mitral valve leaflet and the endocardial surface of the left ventricular free wall, resulting in severe mitral regurgitation, was identified on echocardiogram. Histopathology and immunohistochemistry of this mass and other endocardial masses identified at necropsy for S-100 protein were consistent with a diagnosis of schwannoma. To the authors' knowledge, this is the first case of a benign intracardiac schwannoma described in the left heart of a dog.
一只4岁去势的拉布拉多猎犬因心脏评估前来就诊，以确定1个月前诊断的心源性肺水肿的病因。超声心动图检查发现一个带蒂的大肿块，累及二尖瓣壁叶腹侧和左心室游离壁的心内膜表面，导致严重二尖瓣反流。该肿块及尸检时发现的其他心内膜肿块的组织病理学和免疫组织化学检查显示S-100蛋白，与神经鞘瘤的诊断一致。据作者所知，这是首例在犬左心描述的良性心内神经鞘瘤病例。
