Imaging findings in ten patients with adult fibrosarcoma.

Patient/age/ sex	CT/MRI image	CT Attenuation	MRI					Adjacent bone infiltration	Necrosis or cystic	Fibrous septum
			T1	T2	DWI	Enhancement pattern	Muscles edema
1/47/F	Yes/yes	Iso	Hypo	Mixed		Peripheral enhancement	No	No	No	Yes
2/18/F	No/yes		Hypo	Mixed		Spokes-like enhancement	Yes	No	No	Yes
3/43/F	No/yes		Hypo	Mixed			Yes	No	No	Yes
4/45/F	No/yes		Hypo	Mixed			Yes	No	Yes	Yes
5/51/F	Yes/yes	Iso	Hypo	Mixed		Peripheral enhancement	Yes	No	No	Yes
6/58/F	Yes/yes	Iso	Hypo	Mixed			Yes	No	Yes	Yes
7/46/F	Yes/yes	Iso	Hypo	Mixed	Hyper		Yes	Yes	No	Yes
8/71/F	No/yes		Hypo	Mixed			Yes	No	Yes	Yes
9/75/M	Yes/no	Iso					----	No	No	Yes
10/48/F	Yes/yes	Iso	Hypo	mixed	Hyper	Peripheral enhancement	Yes	No	No	Yes

Iso: isointense; Hyper: hyperintense; Hypo: hypointense; mixed: mixed hyperintense and hypointense signal intensity; the CT attenuation or MRI intensity is in comparison with adjacent muscle.
