3. • Fig B 39-1 Liposarcoma. (A) Sagittal T1-
weighted image shows little fat signal in this
intermediate-grade lesion. (B) On the T2-
weighted image, the tumor has high signal
intensity.46

4. • Fig B 39-2 Malignant fibrous histiocytoma. Axial T2-
weighted image shows the lesion to have generally
high signal intensity with some areas of
inhomogeneity.46

5. • Fig B 39-3 Synovial sarcoma. T2-weighted coronal
image shows a large inhomogeneous mass.
Calcifications appear as low-intensity regions in
the medial aspect of the mass, while hemorrhage
is seen inferiorly.46

6. • Fig B 39-4 Rhabomyosarcoma. Coronal
gradient echo image demonstrates the high
signal intensity of this muscle mass.46

7. • Fig B 39-5 Malignant nerve sheath tumor. T1-
weighted contrast image shows peripheral
enhancement of the large tumor and adjacent
nerve.46
