title: Bilateral orbital metastases from small cell lung cancer: a case report.
abstract: A 46-year-old man with a history of heavy smoking for last 20 years presented with coughing. Computed tomography (CT) scan of the thorax showed a mass in right lung tissue. A fine needle aspiration biopsy (FNAB) confirmed the diagnosis of small cell lung cancer (SCLC), with limited stage at presentation. CT scan and MRI of the orbits demonstrated that the solid masses separately invaded the posterior orbita bilaterally. Then, we made a diagnosis of bilateral posterior orbital metastases from SCLC. Simulation CT imaging was obtained, using head mask. Both of the orbital masses were contoured as the planning target volume. A palliative radiotherapy of 30 Gy was planned, with 3D conformal technique using 12-15 MeV electrons. I presented the case of rare bilateral posterior orbital metastasis due to SCLC.
