Question: What does this MRI mean/say? This is the findings & impression of a MRI of my brain. I have lung cancer in my right upper lung & the lymph nodes between the lungs. Is this saying it is in the right & left sides of my brain & is there a total of 6 or more, etc.?
FINDINGS:
"Compared with the prior CT of the head from 2/9/2016, again noted are multiple intracranial enhancing lesions with mild surrounding FLAIR signal abnormality compatible with metastases. These measure 4 mm in the right superior frontal gyrus (slice 25 of series 10), Additional wound in to millimeter T2 hyperintense lesion in the right superior frontal gyrus medially (series 3 image 25) 3 mm in the left frontal lobe (slice 20 of series 10), 4 mm in the paramedian posterior left parietal lobe (slice 20 of series 10), Two lesions within the right occipital lobe measure up to 3 mm each on slices 16 and 9 of series 10. 2 mm in the left occipital region (best visualized on coronal acquisition imaging 5 of series 11). 6 mm enhancing lesion in the subependymal region of the right lateral ventricular body (slice 19 of series 10) also demonstrate susceptibility artifact, consistent with hemorrhagic products. Lesions in the right cerebellar hemisphere is likely artifactual due to pulsation artifact. (slice 9 of series 10). A linear enhancing focus extending through the right precentral gyrus likely represents a developmental venous anomaly ( slice 25 of series 10). There is no evidence of midline shift or mass effect associated with any of these lesions. The basilar cisterns remain patent. Ventricles are normal in caliber. No hydrocephalus. No extra-axial fluid collection. There is no restricted diffusion to indicate acute intracranial infarction. Orbital contents are normal in appearance. There is mild mucosal thickening in the ethmoid air cells. The mastoid air cells are clear. There is preservation of expected intracranial vascular flow voids. There is preservation of normal T1 calvarial marrow signal."
IMPRESSION:
Findings compatible with multiple small supratentorial parenchymal metastases as described above. The largest measures 6 mm along the right lateral ventricular subependymal region and demonstrates mild associated blood products. No midline shift or significant mass effect.
