case_images: Unenhanced axial CT image shows a large homogeneous right sylvian fissure lipoma with CT value of fat (white arrow). Thick linear calcification is seen at its periphery (black arrow).

case_images: The lesion was surrounded by abnormally thick cortex along its medial border (Figure 1).
case_images: T1-weighted right parasagittal image shows the lesion having typical T1 shortening with bright signal specific of lipomas (white arrow). Multiple linear flow voids are also seen within the lesion (black arrow).

case_images: On MR, the lesion was hyperintense on both T1 and fast spin echo (FSE) T2-weighted images, and showed multiple flow voids (Figures 2 and 3, respectively).
case_images: FSE T2-weighted axial image shows hyperintense lesion with flow voids in right sylvian fissure (white arrow) located within a thickened layer of infolding cortex (black arrow). Subfalcine herniation is also seen (dashed white arrow).

case_images: On MR, the lesion was hyperintense on both T1 and fast spin echo (FSE) T2-weighted images, and showed multiple flow voids (Figures 2 and 3, respectively).
case_images: Post contrast fat sat T1- weighted image shows enhancing vessels within the lesion which are extending up to hemispheric surface (white arrow). There is a marked suppression of the bright signal of the lesion.

case_images: On post contrast fat suppressed T1-weighted images, marked suppression of signal intensity of the lesion was seen consistent with lipoma along with enhancing vasculature within the lesion with its extension to the hemispheric surface (Figure 4).
