Introduction: We studied computed tomography (CT) features associated with BRAF mutated lung cancer.
Materials and methods: CT features of BRAF mutated lung cancers were compared to stage matched lesions without BRAF mutation.
Results: 47 (25%) patients with BRAF mutation and 141 (75%) without BRAF mutation were included. BRAF lesions were most frequently solid 37 (84%), spiculated 22 (50%), and peripheral 37 (84%). No feature of the primary tumor was significantly different between BRAF and non-BRAF groups. BRAF patients were more likely than KRAS patients to have pleural metastases [5 (11%) vs 0 (0%), p=0.045].
Conclusion: No feature of the primary tumor differentiates BRAF lesions from non-BRAF lesions.
