Can someone explain these findings? This was found on an MRI and reads as follows:
INDICATION: 52 years old Female with abnormal CT reporting a right frontal/renal vein associated mass.
COMPARISON: Non-contrast CT October 31, 2023
TECHNIQUE: MRI of the brain was performed on a 1.5 Tesla magnet with use of 5 mL of intravenous Gadavist contrast
BRAIN: No significant hydrocephalus or extracerebral fluid collection is noted. There is an extra-axial avidly enhancing right lesser sphenoid wing mass (35 x 29.5 x 35 mm ) with adjacent enhancing dural tail. There is associated mass effect and deformity of the right frontal, and anterior right temporal lobes without associated edema or abnormal brain parenchymal enhancement. Biparietal convexity diffusion signal abnormality is noted without associated T1, T2 or post-contrast T1 signal abnormality -- probable artifact.
Approximate 2 mm leftward midline shift is noted. There is no acute brain parenchymal infarct, or hemorrhage. Vascular evaluation is not diagnostic on this routine imaging examination. Small left parietal scalp sebaceous cyst is noted.
1. LARGE LESION ALONG RIGHT SPHENOID WING -- LIKELY MENINGIOMA.
2. APPROXIMATE 2 MM LEFTWARD SHIFT.
Specifically, what does the part about the "biparietal convexity diffusion signal abnormality" mean? And what are the functions of the brain associated with the right frontal and anterior right temporal lobe, and how could the deformity of these areas and leftward shift effect brain function?
I would so appreciate any feedback or answers. I don't see the neurosurgeon until the beginning of January.
Thank you so much!
