[MRI features of ventricular system tuberculosis].
OBJECTIVE
To study the MRI features of ventricular system tuberculosis.


METHODS
Nineteen patients with ventricular system tuberculosis in our hospital from Mar. 2009 to Sep. 2014 were retrospectively identified. Their clinical features and cranial MRI characteristics were reviewed.


RESULTS
There were 13 males and 6 females, aged from 15-81 years(mean 37±16). Eight patients had intraventricular tuberculosis, with 5 long striped or irregular shaped intraventricular tuberculosis and 3 with ventricular tuberculoma. Six patients had tubercular ependymitis and 5 had intraventricular tuberculosis along with tubercular ependymitis. The lesions of 14 patients were in the lateral ventricle; 13 in occipital or temporal horn of lateral ventricle, 9 complicated by tubercular meningitis, and 10 complicated by brain tuberculoma. The lesion of 5 patients were in the fourth ventricle, 5 in the postmedian of the fourth ventricle, 5 complicated by tubercular meningitis and 4 complicated by hydrocephalus. There were 4 cases with ring-enhancement and 15 with heterogeneous enhancement. Ten cases were complicated by peripheral edema.


CONCLUSIONS
The diagnosis of ventricle system tuberculosis is difficult due to its low incidence. The site, cranial MRI characteristics, the patterns of enhancement and complications have certain specificity and are useful in the diagnosis of ventricular system tuberculosis.
