概括

主要骨内膜瘤 (PIMs) 是一种罕见的头骨瘤. 图像显示CT上具有高静止病变的明确病变,MRI上显示特定信号强度,有助于诊断.

科学领域:

神经辐射学神经辐射学
在瘤学瘤学.
骨辐射学骨辐射学

背景情况:

主要骨内膜瘤 (PIMs) 是一种罕见的瘤,来自骨内的异位膜细胞.
这些瘤通常发生在老年人中,并且经常涉及calvaria.

研究的目的:

确定PIM的特征成像特征.
为了协助PIMs的精确放射性诊断.

主要方法:

从9个病理确认的PIM病例的临床和放射学数据的回顾性审查.
计算机断层扫描 (CT) 和磁共振成像 (MRI) 发现的全面分析.

主要成果:

病变通常会影响体内外板,看起来很周围.
CT显示过弱化/异弱化固体成分与频繁的高静止.
核磁共振显示T1,T2,FLAIR,DWI和ADC序列上的特征信号强度,具有激烈的对比后增强.

结论:

PIMs具有明显的成像特征,包括CT上的关参与和超静止症.
特定的MRI信号特征和增强模式对于诊断至关重要.
识别这些特征会引起对PIM的怀疑,从而促进及时诊断.

Cranial Bones: Superior and Posterior View

Cranial Bones: Superior and Posterior View

The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
