title: Plantar fibromatosis may adopt the brain gyriform pattern of a low-grade fibromyxoid sarcoma.
abstract: We report the case of a 42-year-old man with histologically proven plantar fibromatosis (Ledderhose disease) demonstrating an uncommon brain gyriform pattern at MRI, so far exclusively described in the low-grade fibromyxoid sarcoma (LGFMS). An acoustic posterior enhancement at ultrasound, a high intensity on T2w and post-contrast T1wMR images were unusual and related to a high tumor cellularity at histology with no myxoid tissue. The juxtaposition of areas of high and low cellularity (with more fibrous material) in a multilobulated mass built a brain gyriform pattern at MR, similar to what was so far described exclusively in LGFMS. This case demonstrates that the brain gyriform pattern may also be observed in other soft tissue fibrous tumors with no myxoid material but with high cellularity areas alternating with fibrous zones of low cellularity.
