tuberculoza cavitara
Caverna de gradul I

Imagine hipertransparenta, cu contur anfractuos, in masa infiltratului

TUBERCULOZACAVITARA
tb cavitara
Caverna grad II (elastica)

Are perete propriu, subtire, elastic

Contur net

Caverna grad III (scleroasa)

Pereti grosi, rigizi, fibrozati

Contur neregulat

Scleroza pericavitara si leziuni combinate in jurul ei

TB CAVITARA
tuberculom apical
Apare si in tuberculoza primara si in cea secundara

La 5% dintre pacienti este singura leziune care apare pe Rx

Opacitate rotunda , ovalara , incapsulata, structura omogena sau neomogena, central poate prezenta cazeificare

Poate fi solitar sau multiplu

Diametru intre 0,5-4cm

Contur net

Calcificari in 20-30%din cazuri cu aspect nodular sau concentric

Rx seriate arata stabilitatea leziunii in timp

Leziuni satelite in proportie de >80%

TUBERCULOM APICAL
tb miliara
Poate aparea la orice varsta

Se produce prin diseminare hematogena

Nodulii au 1-3 mm, bine individualizati

Localizati bilateral, omogen distribuiti

Initial mai numerosi la nivelul bazelor , ulterior vizibili si in lobii superiori

Nodulii reprezinta granuloame TB

Tuberculoza miliara poate fi discreta la persoane cu status imun bun

TB miliara
