CT patterns of nodal disease in pediatric chest tuberculosis

Figure 1 Computed tomography chest of a patient (A) showing large, conglomerate rim enhancing nodes, with central necrosis (B) post anti-tubercular treatment, showing resolution of adenopathy, with appearance of perinodal fat.

Figure 2 Pretreatment computed tomography (A) showing conglomerate, inhomogenous paratracheal lymph nodes and follow up computed tomography (B) showing reduction in size of the nodes to < 1 cm size, with reappearance of perinodal fat.

Figure 3 Computed tomography (A) showing conglomerate, homogenous paratracheal lymph nodes and (B) showing reduction in size of the nodes (< 1 cm) after treatment.

Figure 4 Pretreatment computed tomography (A, B) showing calcified precarinal, prevascular, right hilar, and azygoesophageal nodes, with necrotic areas and follow up computed tomography after anti-tubercular treatment (C, D) showing resolution of necrotic areas, with residual calcification.
