The left parafalcine/falcine mass measures 19 x 31 x 12 mm, and has internal signal consistent with fat on all sequences. It is surrounded by low signal on all sequences, almost similar presenting calcification/ossification. A similar second but much smaller region projecting on the right side of the falx, more posteriorly and superiorly, measuring only 6 x 12 x 12 mm is noted. Neither region demonstrate any abnormal enhancement, and the remainder of the brain is normal in appearance.
Appearances are characteristic, albeit pronounced, of ossification of the falx with central fatty marrow.
