Hello I had a ct scan and was wondering what a portion of the findings mean. There is linear high density along the posterior falx in the midline with maximum thickness of approximately 3mm. Extensive artifact in the posterior fossa is present. Hi density is noted about the region of the midbrain which is likely artifactual. Impression Linear area of increased density along the falx posteriorly. this may be owing to asymmetric area of hemorrhage cannot be excluded. additionally , there is extensive artifact at the level of the posterior fossa and midbrain, area of asymmetric high density is noted about the midbrain likely artifactual.
