MRI findings of intracranial tuberculosis of three cases at different stages and locations

Merkezi sinir sistemi (MSS) tüberkülozu dünyanın belli bölgelerinde yaygın bir endemik sorun olmaya devam eden bulaşıcı bir hastalıktır. Intrakranial tüberküloma genellikle meningeal irritasyon ve artmış intrakranial basınç semptomları ile ortaya çıkan granülomatöz yer kaplayan kitle lezyonudur. Biz farklı aşamalarında ve lokalizasyonlarda intrakraniyal tüberkülozu olan üç olgunun manyetik rezonans görüntüleme (MRG) bulgularını bildirdik. Tüberkülozun MSS tutulumu tüberküloz menenjit ve tüberküloma şeklinde görülür. Tüberküloma formu daha sık görülür. Vücudun başka yerinde tüberkülozu olan ya da tüberkülozun endemik olduğu bölgede yaşayan hastaların MRG sinde halkasal şekilde kontrast tutan düşük sinyal intensiteli lezyon ya da T2 ağırlıklı sekanslarda geçici hiperintens sinyallerin görülmesi halinde ayırıcı tanıda MSS tüberkülozu düşünülmelidir.

Farklı evre ve lokalizasyonda intrakranyal tüberkülozu olan üç olgunun MRG bulguları: Olgu sunumu

Central nervous system (CNS) tuberculosis is an infectious disease process that continues to be a prevalent endemic problem in certain world regions. Intracranial tuberculomas are space-occupying masses of granulomatous tissue which generally emerge with the symptoms of meningeal irritation and increased intracranial pressure. We have reported magnetic resonance imaging (MRI) features of three cases of intracranial tuberculosis that were at different stages and locations. The involvement of the CNS by tuberculosis (Tbc) occurs often in the form of the tubercular meningitis and tuberculoma. The tuberculoma form is more common. The presence of a ring enhancing low signal lesions on T1 weighted images or a transient hyperintense signal on T2 weighted images in MRI of the patients who have tuberculosis elsewhere in the body or live in region where tuberculosis is endemic should suggest CNS tuberculosis.
