“…We reviewed 16 cases of pathogenic negative tuberculous meningitis since 2020 [ 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ] (see Supplementary Table S4 ). These case reports are similar to our cases, mainly because of their atypical clinical manifestations or lesion sites, such as one-and-a-half syndrome [ 35 ], nonconvulsive status epilepticus [ 36 ], oculomotor palsy [ 38 ], lesions involving clivus [ 31 ], and midbrain [ 32 ]. Although there was no etiological diagnostic evidence, clinicians highly suspected tuberculous meningitis based on the general symptoms of tuberculosis, CSF examination, and imaging findings, and began empirical ATT treatment, which ultimately led to a good clinical outcome for most patients.…”
