ABSTRACT. Low-grade fibromyxoid sarcoma (LGFMS) is a rare soft-tissue sarcoma characterised by a deceptively bland histological appearance and a paradoxically aggressive behaviour.LGFMS usually presents in young-to-middle-aged adults as a painless, slow-growing mass with the potential for local recurrence and metastasis despite low-grade histology. Several case reports have described variable MR findings of LGFMS without haemorrhage or necrosis. We report here on the MR findings in two young women with haemorrhagic LGFMS in the thigh.
