Abstract:
Objective To analyze and evaluate the characteristics of cerebral sparganosis on MRI. Methods MRI appearances of 15 cases of cerebral sparganosis proven by pathology or serological test were retrospectively studied.Results A total of 21 lesions were found,some of them were single and some were multiple but asymmetrical.8 lesions were found in parietal lobe,6 in frontal lobe,2 in temporal lobe,2 in oceipital lobe,1 in basal ganglia,1 in cerebellar hemisphere and 1 in pons.The lesions carried slightly hypointense on T_1-weighted images and moderate hyperintense on T_2-weighted images.Most lesions showed pefilesional brain parenchyma edema.Enhanced MRI was performed in 10 cases,and all of them demonstrated abnormal enhancement such as peripheral ring-type,tortuous beaded shape or serpiginons tubular shape enhancement.Follow-up MR images in 6 eases were analyzed,and the location and shape of the lesions changed in 2 of them.Conclusion There are some specific MRI findings on cerebral sparganosis.Enhanced MRI and follow-up examination are important for the diagnosis of cerebral sparganosis.
