Abstract
Miliary pattern on radiographs are attributed always to tuberculosis even though the differential diagnoses of miliary pattern is very wide. This pattern is most commonly caused by infectious diseases and rarely by malignancies. Primary lung cancers presenting with miliary shadows is extremely rare. Here we report a case of 50-year old female, presenting with 15 days of symptoms and CXR PA view showing bilateral diffuse miliary nodules. HRCT Chest confirmed the miliary pattern and also showed a mass in left lower lobe. Microbiological tests for tuberculosis and fungal infections were negative. CECT Chest gave impression of left lower lobe suspected malignant lung mass with pulmonary metastasis. Malignancy was confirmed by CT guided FNAC as Adenocarcinoma lung. PET scan didnot reveal metastasis in other organs. CONCLUSION : Miliary pattern does not always indicate tuberculosis and other possibilities should be evaluated.
