Objective To discuss the ultrasonographic characteristics of schistosomal appendicitis lesions. Methods Among the patients with schistosomal hepatopathy who were discovered by Color Doppler ultrasound in Huzhou Central Hospital from January 2012 to December 2015,50 cases with clear history of schistosomiasis and treatment were chosen as a schistosom?al hepatopathy group,meanwhile,50 normal people,who came from non?endemic areas,without schistosomal hepatopathy and schistosomiasis history were chosen as a control group. The two groups were examined by ultrasound scan of the appendix ,and the data of the largest diameter of the appendix and the thickness of the appendix wall were collected,and the sonographic char?acteristics of their appendixes,such as whether the echo of the appendix wall was even or not,were observed. Results The minimum internal diameter of the appendix cavity and the thickness of the appendix wall of the schistosomal hepatopathy group were(2.090 ± 0.790)mm and(1.332 ± 0.313)mm ,respectively,the former was significantly narrower than that of the control group,while the latter was significantly thicker than that of the control group(t=2.647,-4.526,respectively,both P<0.05). The proportions of those with inhomogeneous echo,indistinctness structure,uneven thickening of the appendix wall,as well as having intestinal contents in the appendix cavity in the schistosomal hepatopathy group were higher than those in the control group(χ2=12.000,18.537,24.008,4.244,respectively,all P<0.05). Conclusions Schistosomal appendicitis lesions have obvious ultrasonographic characteristics under ultrasound. Ultrasound can play an important role in judging whether the appen?dix of schistosomiasis patients is involved and discovering the lesion of appendix early.

Mild encephalitis/encephalopathy with reversible splenial lesion has special clinical-imaging features. According to the extent of lesion involvement, it can be divided into type Ⅰ and type Ⅱ. Clinically, type Ⅰ is more common, and type Ⅱ is rare. A rare case of recurrent type Ⅱ mild encephalitis/encephalopathy with reversible splenial lesion is reported. The patient presented with typical type Ⅱ mild encephalitis/encephalopathy with reversible splenial lesion for the first time, involving the corpus callosum and the deep white matter, and the lesions disappeared after a short-term reexamination. Two years later, the lesions recurred, and the scope of the lesions was similar to that of the first time, and the lesions disappeared after a short-term reexamination. The clinical and imaging findings are analyzed in combination with relevant literatures review in order to deepen the understanding of the disease and improve the level of diagnosis and treatment.
