CTICasesMiliary Tuberculosis with Retroperitoneal Lymphadenitis
Imaging findings
Chest radiograph and CT in a 26-year-old female show a 'spray paint' pattern of diffuse, tiny, homogeneous miliary nodules throughout both lungs, accompanied by necrotic retrocrural and retroperitoneal lymphadenitis, representing disseminated tuberculosis.
Key takeaways
Miliary tuberculosis represents hematogenous dissemination of Mycobacterium tuberculosis. On radiographs, it presents as a fine, diffuse reticulonodular pattern (spray paint sign). necrotic abdominal lymphadenitis is a classic coexisting feature.
