Unusual presentation of miliary tuberculosis in a 12-year-old girl: a case report.

BACKGROUND: Miliary tuberculosis (TB) is a lethal hematogenous spread form of mycobacterium tuberculosis with approximately 15-20% mortality rate in children. The present report highlights the clinical manifestations of an unusual presentation of miliary tuberculosis in a 12-year-old girl. CASE PRESENTATION: In this case, extensive lung involvement was presented despite the absence of respiratory symptoms. Also, some central hypo-intense with hyper-intense rim nodules were detected in the brain's pons, right cerebral peduncles and lentiform nucleus. CONCLUSION: The results of this study showed that severe miliary TB may occur even in a person who received the Bacille Calmette-Guérin (BCG) vaccine.
