[Silent brain metastasis in the initial staging of lung cancer: evaluation by computed tomography and magnetic resonance imaging].

Objective: Brain metastases are common in patients with lung cancer and influence both prognosis and treatment decisions. The aim of this study was to evaluate the incidence of silent brain metastasis during the initial staging of lung cancer using cranial computed tomography (CT) and magnetic resonance imaging (MRI).

Patients And Methods: We performed a retrospective analysis of lung cancer patients with no neurologic signs or symptoms who were evaluated by cranial CT, MRI, or both at the time of diagnosis.
