Clinical and imaging characteristics of cerebral schistosomiasis.

In recent years, there has been a trend for increased incidence of cerebral schistosomiasis. It is often misdiagnosed because of the diversity of clinical symptoms. We wished to explore clinical characteristics and imaging findings in cerebral schistosomiasis. We retrospectively analyzed clinical data, laboratory tests, CT, and MRI results in 11 patients with cerebral schistosomiasis. All patients had chronic cerebral schistosomiasis (five with epilepsy type, five with brain tumor type, and one patient with stroke type). All patients with brain tumor type were misdiagnosed as having gliomas. There were typical findings on CT and MRI. In conclusion, clinical manifestations of cerebral schistosomiasis are variable, and the rate of misdiagnosis is high. For more precise diagnosis, a combination of laboratory and imaging data is required.
