目的 探讨B超、CT和MRI检查对眼囊尾蚴病的影像学诊断价值。方法 2 9例眼囊尾蚴病患者 ,B超检查 2 1例 ,CT检查 19例 ,MRI检查 6例。结果 眼囊尾蚴病活动期 ,B超检查可探及眼内和眶内寄生虫囊泡、囊尾蚴蠕动及眼外肌不规则增粗 ;CT检查可发现眼眶内寄生虫囊泡及病变的眼外肌 ;MRI检查可发现眼内和眶内寄生虫囊泡及病变的眼外肌。眼囊尾蚴病非活动期 ,B超及CT检查均可发现眼内或眼外肌内的钙化斑。结论 眼囊尾蚴病影像表现随囊尾蚴在眼内的寄生部位和存活状态而不同。B超检查可作为诊断眼囊尾蚴病的首选方法 ,MRI和CT检查可分别作为诊断活动期及非活动期眼囊尾蚴病的补充方法。
Objective To investigate the diagnostic value of ultrasound, CT and MRI in the diagnosis of ophthalmicercosis. Methods Twenty-nine patients with cysticercosis were examined with B-ultrasound in 21 cases, CT in 19 cases and MRI in 6 cases. Results Ocular cysticercosis in the active phase, B-ultrasound can detect intraocular and orbital parasitic vesicles, cysticercosis and extraocular muscle irregular thickening; CT examination can be found in orbital parasites vesicles and lesions of the eye Outer muscle; MRI examination can be found intraocular and orbital parasites vesicles and lesions of extraocular muscles. Ocular cysticercosis inactivity, B ultrasound and CT examination can be found intraocular or extracranial calcified plaque. Conclusion The manifestations of cysticercosis are different with the cysticercus parasites in the eye and their survival status. B-ultrasound diagnosis of cysticercosis can be used as the preferred method of MRI and CT examination can be used as diagnosis of active and inactive cysticercosis method of supplement.
