Brain metastasis appears in 40% of patients with primary lung cancer and it is the most common setting in which radiosurgery is employed. The trials showed a survival benefit for patients with a single brain metastasis treated with whole brain radiotherapy and stereotactic radiosurgery. This case is presented to show the radiosurgical approach for brain metastasis.

67 years old male patient was operated for the right lung upper lobe mass in October 2011. Histopathology turned out non small cell lung cancer and the immunophenotype was adenocarcinoma, with a staging 2A (T2bN0M0). A 1,4x1,6 cm diameter mild enhancing lesion was established at the right frontal lobe with cranial MRI and we decided to follow up. When a progression was determined in the lesion (to 3 cm) on control MRI performed in January 2013, surgery was recommended but the patient was medically unfit so he was send to our clinic. In our clinic, whole brain radiotherapy, systemic chemotherapy and stereotactic radiotherapy to the solitary brain metastasis treatments were given, respectively.

20% to 40% of patients with cancer develop metastasis to brain during the course of their illness, representing a significant healthcare problem. Presenting symptoms include headache (49%), focal weakness (30%), mental disturbances (30%), gait ataxia (20%), seizures (18%), speech and visual difficulty (10%).
