“…When fibrous connective tissue appears within the lipoma, the septa will show a decreased signal (hypointense) on all pulse sequences (Fig 3). Fatsuppressed T1-weighted images with contrast will demonstrate signal intensity suppression of the lipoma without enhancement of the lipoma or the septae 15 (Fig 4).…”

“…Nonadipose tissue comprising more than 25% of the lesion is also a feature consistent with welldifferentiated liposarcoma. 15,16 With imaging, characteristics that would exclude the diagnosis of a lipoma include thick septations, soft tissue elements, and nodular enhancing regions. 9 The MRI examination revealed none of these findings.…”

“…To the best of our knowledge, there has been no report of a protruding lipoma like the present cases. Though they were large, and looked heterogeneous in MRI (case 1), pathological examination showed no evidence of malignancy (5,6,7,8,9). The following diseases should be considered in the differential diagnosis based on the tumor location and/or radiological findings: well-differentiated liposarcoma, accessory scrotum, inguinal herniation.…”

“…Magnetic resonance images are more effective than CT on the differentiation of the lipomas and liposarcomas, including the well-differentiated variant 7 . However, the histopathologic exam is essential to conclude the diagnosis 3 .…”
