Isolated pontine tuberculoma presenting as “fou rire prodromique”

Case report

Restricted access

The authors present the case of a young child with “fou rire prodromique” as an initial manifestation of pontine tuberculoma. This report is the first description of fou rire prodromique as the presenting sign of CNS tuberculosis. The combination of clinical information and CT findings allowed for precise localization of the lesion and suggested tuberculoma as the possible etiology.
