MRI findings in tuberculous meningo-encephalitis

[Normal and abnormal meningeal enhancement: MRI features]

The authors describe normal imaging of the meninges and meningeal spaces and MR (magnetic resonance) imaging findings in tumoral and nontumoral diseases. Dural or/and pial enhancement may be related to tumoral, infectious or granulomatous diseases.

Tuberculous meningitis in native Dutch children: a report of four cases

Although it is believed that in the western countries tuberculosis is a disease confined to high-risk groups such as immigrants, we describe four cases of tuberculous meningitis (TBM) in native Dutch children. The inverse relation between the delay in starting therapy and the clinical outcome makes early diagnosis of TBM essential. The often non-specific presenting symptoms and laboratory results, the time-consuming character of cultures and the unfamiliarity of western medical staff with the disease all may contribute to a delay in diagnosis of TBM. We believe that especially gadolinium-enhanced MRI or contrast-enhanced CT can be very helpful in the early diagnosis. Although not specific, hydrocephalus and basal meningeal enhancement on MRI or CT, together with the clinical suspicion can suggest the diagnosis to such an extent that there is enough reason to start antituberculous treatment.
