54-year-old male history of newly diagnosed stage IV non-small cell lung carcinoma. Evaluate for metastatic lesions. There are no areas of restricted diffusion to suggest an acute ischemic infarct. There is mildly increased confluent T2/flair signal abnormality within the periventricular white matter, nonspecific. No evidence of acute or chronic intracranial hemorrhage. No abnormal enhancement is appreciated to suggest metastatic disease to the brain. The basal cisterns are intact. The ventricles and sulci are symmetric. The left frontal sinus is opacified. Flow-voids are appreciated in the major intracranial vessels. There is a 3.9 x 1.7 cm T1/T2 bright smoothly marginated ovoid lesion located within the soft tissues of the right occipital scalp which represents a subcutaneous lipoma. The mastoid air cells are unremarkable. The calvarium and remaining soft tissues of the scalp are within normal limits.
1. No evidence of metastatic disease to brain.2. Mildly increased T2/FLAIR signal abnormality within the periventricular white matter which is nonspecific but likely related to chronic small vessel ischemic disease.3. Left frontal sinus opacification.4. Small lipoma in the right occipital soft tissues.
