Abstract : Lung squamous cell carcinoma (SCC), a major subtype of non-small cell lung cancer (NSCLC), typically metastasizes to the brain, bone, adrenal glands, and liver. Axillary lymph node metastasis (ALNM) is exceedingly rare and often mimics breast malignancy, risking misdiagnosis. We present a rare case of a 74-year-old chronic smoker with isolated ALNM, brain, spinal, and retroperitoneal metastases without mediastinal involvement. Diagnosis was confirmed through ultrasound, mammography, contrast-enhanced CT (CECT), MRI, and fine-needle aspiration cytology (FNAC). Conclusion: This case underscores the need for radiologic vigilance to identify atypical metastatic patterns and avoid diagnostic errors.

Keywords : Axillary Lymph Node Metastasis, Lung Cancer, Brain Metastasis, Radiologic Correlation.
