Figure 3
A 53-year-old woman with spindle cell lipoma. (a) Axial T1- and (b) T2-weighted images of the left shoulder showing a deep-located mass with mean size of 6.4 cm. Scattered areas of high signal intensity on T1-weighted image are noted, suggesting intratumoral fat component (arrows). (c) Axial fat-suppressed contrast-enhanced T1-weighted image revealed heterogeneous enhancement. (d) Split fat sign was observed between the tumor and triceps brachii muscle on sagittal T2-weighted image (arrowheads). (e) The mean and minimum ADC values of the lesion were measured to be 2.60 × 10−3 mm2/s and 1.90 × 10−3 mm2/s, respectively. The probability of malignancy was calculated to be less than 0.1 by both models I and II.
