New lung cancer diagnosis. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are subcentimeter areas of enhancement superficially along the cortex of the right precentral and postcentral gyri, with associated high T2 signal in the cortex. 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, paranasal sinuses, and scalp soft tissues are grossly unremarkable. However, there is a subcentimeter enhancing lesion in the right frontal bone and a partially imaged lesion in the left C3 vertebra.
1. Subcentimeter areas of enhancement superficially along the cortex of the right precentral and postcentral gyri are compatible with metastases, perhaps leptomeningeal in nature.2. A right frontal bone lesion and a partially imaged lesion in the left C3 vertebra is also compatible with metastatic disease.
