case_images: Chest X-ray. This is a posteroanterior chest X-ray taken of the patient at the time of diagnosis. It demonstrates the opacity in the left upper lobe of the lung consistent with lung cancer.

case_images: His general practitioner requested a chest X-ray that demonstrated a large mass in the left parahilar region extending into the anterior segment of the left upper lobe (Figure 2).
case_images: Coronal head computed tomography slice. This image is a coronal slice of the head computed tomography performed on the patient. It demonstrates a single intracranial metastasis with destruction of the parietal bone and extension of the lesion into the extracranial soft tissues.

case_images: A contrast-enhanced computed tomography (CT) of his chest and a non-contrast CT of his head were requested (Figure 3).
case_images: Coronal chest computed tomography slice. This image is a coronal slice of the chest computed tomography taken of the patient. It demonstrates a large squamous cell carcinoma of the lung in the left upper lobe.

case_images: The chest CT demonstrated the presence of a mass in the anterior left upper lobe measuring 8.78x7.40x7.79cm extending to and invading the anterior and lateral pleura (Figure 4).
case_images: Sagittal head computed tomography slice. This image is a sagittal slice of the head computed tomography performed on the patient. It demonstrates the intracranial metastasis.
