摘要

背景:包虫病是一种寄生虫感染,常见于地方病流行地区。目的:描述肌肉骨骼包虫病的磁共振成像(MRI)特征,并强调诊断包虫囊肿的特殊发现:回顾性分析了 2000 年至 2022 年期间被诊断为肌肉骨骼包虫病的 29 例病例的 MRI 扫描结果。对包虫囊肿的定位、大小、外观(单球形或多球形)、信号特征、边缘征、内隔膜和膜的存在以及钆增强模式进行评估:研究共纳入 29 名确诊为包虫囊肿的患者。其中,18 例病变位于骨骼,11 例位于软组织。骨水瘤囊肿在核磁共振成像中的 T1 加权图像上显示为异质的低至中等信号强度,而在髓质骨的 T2 加权图像上显示为高信号强度。15/18例患者的骨皮质也受到破坏,并扩展到邻近的软组织平面。在 8/11 例囊肿位于肌肉组织的病例中,MRI 观察到 "囊肿或囊肿内囊肿 "的表现。7/11例中观察到边缘征,2/11例中观察到 "睡莲 "征:结论:磁共振成像以其独特的成像特征为包虫病的诊断提供了有价值的信息。了解水包虫囊肿在核磁共振成像上的不同形态可能有助于该疾病的诊断。

Magnetic resonance imaging characteristics of musculoskeletal hydatid disease.

Background: Hydatid disease is a parasitic infection seen in endemic areas. Musculoskeletal hydatid disease is rarely reported.

Purpose: To describe the magnetic resonance imaging (MRI) features of musculoskeletal hydatid disease and to highlight the specific findings in the diagnosis of hydatid cysts.

Material and methods: The MRI scans of 29 cases diagnosed as musculoskeletal hydatid disease between 2000 and 2022 were retrospectively analyzed. The localization, size, appearance (unilocular or multilocular), signal characteristics, rim sign, presence of internal septa and membrane, and gadolinium enhancement pattern of hydatid cysts were evaluated.

Results: A total of 29 patients diagnosed with hydatid cyst were included in the study. Of the lesions, 18 were localized in bone and 11 were in soft tissue. The bone hydatid cysts on MRI showed heterogeneous low to intermediate signal intensity on T1-weighted images and high signal intensity on T2-weighted images in the medullary bone. In 15/18 patients, there was also cortical destruction and extension into the adjacent soft tissue planes. In 8/11 cases where the cyst was located in muscle tissue, the "cyst or cysts within a cyst" appearance was observed on MRI. The rim sign was observed in 7/11 cases and the "water lily" sign was noted in 2/11 cases.

Conclusion: MRI provides valuable information for the diagnosis of hydatid disease with its distinctive imaging features. Knowledge of the different patterns of hydatid cysts on MRI may be helpful in the diagnosis of this disease.
