[A clinical report of five cases of central nervous system miliary tuberculomas first diagnosed by neurologists].

To explore the clinical characteristics and imaging features of miliary tuberculomas in central nervous system(CNS). A total of 5 cases diagnosed with tuberculosis in CNS first diagnosed by neurologists in Navy General Hospital of PLA were enrolled in the study. All clinical and imaging data were collected and analyzed retrospectively. The main initial symptoms were fever and headache (4/5). Multiple diffused miliary lesions were shown by brain MRI, with maximum diameter ranged from 1-4 mm and ring-shape or nodular enhancement after gadolinium injection. As mycobacterium tuberculosis could seldomly be found in serum and cerebrospinal fluid, contrast MRI remains the effective method for detecting miliary tuberculomas in CNS.
