Assess for metastasis: Newly diagnosed lung cancer. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and mastoid air cells are grossly unremarkable. There appears to be diffuse enhancement along the left temporalis tendon.
1. No evidence of intracranial metastases. 2. Apparent diffuse enhancement along the left temporalis tendon may be inflammatory rather than neoplastic in nature. However, imaging follow up may be useful.
