We report herein the case of a 77-year-old man with a left ventricular tumor originating from the papillary muscle of the left ventricular wall, in whom a successful tumor resection with mitral valve replacement was performed. The pathological diagnosis of the tumor was confirmed as cardiac fibroma. His postoperative course was uneventful and he is currently well with no signs of recurrence 2 years after surgery. 相似文献

目的:评价X线平片和CT扫描在诊断长骨非骨化性纤维瘤中的作用,旨在提高对该病的诊断与鉴别诊断水平。方法:对16例经手术病理证实的非骨化性纤维瘤的X线平片和CT特征进行回顾性分析。结果:肿瘤部位为胫骨9例,股骨6例,腓骨1例。肿瘤形态为卵圆形,肿瘤的长径2.0~8.0cm,肿瘤边缘均有硬化边。根据X线平片及CT所见分为2型:皮质型或偏心型(12例)和骨髓型或中心型(4例)。讨论:非骨化性纤维瘤的X线平片和CT表现具有特征性,对诊断和鉴别有重要作用。 相似文献

Fibrous metaphyseal defects — determination of their origin and natural history using a radiomorphological study 总被引:5,自引:0,他引:5
The radiomorphological appearance of fibrous metaphyseal defects (FMDs) is demonstrated by long-term follow-up studies. A characteristic radiomorphological course rather than a typical single appearance can be established. These findings correlate well with the duration of these tumor-like lesions; therefore, the radiological findings allow conclusions to be made about the age of a fibrous metaphyseal defect. In addition, the characteristic locations of FMDs will be explained in respect of their origins at insertions of tendons and ligaments. 相似文献

The case describes a 38-year-old woman presenting a multilocular radiolucency affecting the entire right half of the lower jaw, with an unerupted third molar displaced to the region of the coronoid process. The histological study showed the presence of fibroblasts, focally with pleomorphic nuclei, dense collagen and an odontogenic epithelium with dystrophic calcifications. A cyst with an important inflammatory infiltrate was, moreover, observed. 相似文献

Since peripheral odontogenic fibroma (POF) is characteristically described as a solitary lesion and no diffuse POF had been reported in the literature, our cases should be considered as extremely unusual. Three diffuse cases of POF are described of which one case was seen in association with ocular and skin lesions. The question arises whether POF should be considered as a true odontogenic tumor rather than a diffuse hamartomatous lesion caused by uncontrolled induction of the gingiva. It is also possible that such lesions could be part of a yet undescribed syndrome. 相似文献

The intraperitoneal mass most commonly encountered after blunt abdominal truama is a hematoma. However, one must also consider
unusual bulky tumors that can have imaging characteristics similar to those of hematoma. The most typical of these neoplasms
is lymphoma, but a desmoplastic small cell tumor also may be observed. The presentation and imaging findings of a desmoplastic
small tumor are described. 相似文献
