CTICasesSparse Miliary Tuberculosis with a Near-Normal Chest Radiograph
Imaging findings
A patient's chest radiograph is nearly unremarkable, with only subtle, sparse small nodules that are easy to overlook and no definite lymphadenopathy; a thin-walled cystic space is also noted, possibly a sequela of prior disease.
Key takeaways
Even a chest radiograph that appears largely unremarkable, with only very sparse small nodules, can represent active miliary tuberculosis -- this patient tested positive for TB despite the deceptively mild radiographic findings, reinforcing that low nodule burden does not exclude active mycobacterial disease.
