概括
皮质瘤是罕见的软组织瘤. 这项研究详细介绍了三个异常MRI发现的病例,强调了由于纤维化和软骨转化等二次变化而需要活检的必要性.
科学领域:
- 整形外科 整形外科 整形外科
- 放射学 放射学是一门学科.
- 病理学 病理学 病理学
背景情况:
- 脂质瘤是常见的软组织瘤,但低皮脂肪 (IFP) 脂质瘤很少见.
- 这些罕见的IFP脂瘤可以穿透关节囊并通过皮下扩散.
- 患者经常出现膝盖质量,但没有疼痛或运动范围有限,诊断延迟很长.
研究的目的:
- 报告三个罕见的IFP脂瘤病例,表现异常.
- 描述这些案例中磁共振成像 (MRI) 发现的特征.
- 强调诊断的挑战和活检的必要性,以准确诊断.
主要方法:
- 一系列病例报告了三名IFP脂瘤患者.
- 详细分析患者人口统计,临床表现和症状持续时间.
- 综合审查MRI发现,包括T1加权成像特征.
- 手术切除和随后的切除瘤的组织病理学检查.
主要成果:
- 三名女性患者 (63,74,64岁) 呈现出来自IFP的膝盖质量.
- 核磁共振扫描显示了通过关节囊的皮下延伸,脂质瘤在T1加权成像上显示分散的低信号区域.
- 切除的瘤大约为6-7厘米; 组织病理学证实了带有部分纤维化的脂质瘤,并在一个案例中证实了软骨转化.
结论:
- IFP脂瘤可能表现出二次变化 (纤维化,软骨转化),导致非典型的MRI发现.
- 这些发现可以模仿其他疾病,需要活检来区分非典型的脂质瘤或霍法病.
- 精确的IFP脂瘤诊断需要对临床,成像和病理数据进行仔细的关联.

External Anatomy of the Kidney
4.4K
The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

Bones of the Lower Limb: Femur and Patella
9.0K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Hypodermis
8.3K
The hypodermis (the subcutaneous layer or superficial fascia) is present directly below the dermis. It connects the skin to the underlying fascia (fibrous tissue) of the bones and muscles. It is not strictly a part of the skin, although the border between the hypodermis and dermis can be difficult to distinguish. The hypodermis consists of well-vascularized, loose, areolar connective tissue and adipose tissue, which functions as a mode of fat storage and provides insulation and cushioning for...
