Abstract

Intracranial lipoma is a rare entity, accounting for less than 0.5% of intracranial tumors, which usually develops in the callosal cisterns. We report a case of lipoma with an unusual location; in the high parietal convexity combined with massive calcification, and no underlying vascular malformation or congenital anomaly.

  Fig. 1 Brain MRI of a 63-year-old male patient with an intracranial convexity lipoma in the right parietal convexity. A. Sagittal T1-weighted magnetic resonance (MR) image shows a hyperintense mass (arrows) in the right parietal convexity. A heterogenous signal intensity of calicification (arrowhead) under the mass is noted in all sequences. B. Coronal T2-weighted MR image shows intermediate signal intensity of the mass (arrows) with heterogenous low signal intensity of calcification (arrowheads). C. Coronal T1-weighted MR image with fat-saturation shows a hypointense mass (arrows) with heterogenous low signal intensity of calcification (arrowheads). D. Contrast-enhanced, coronal T1-weighted MR image with fat-saturation shows no evidence of enhancement and mass shows intermediate signal intensity of mass (arrows) with heterogenous low signal intensity of calcification (arrowheads).
