| Abstract: |
| Objective?The aim of this study was to analyze the imaging features of alveolar soft part sarcoma (ASPS).
Methods?The imaging features of 11 cases with ASPS were retrospectively analyzed.
Results?ASPS mainly exhibited an isointense or slightly high signal intensity on T1-weighted imaging (T1WI), and a mixed high signal on T2-weighted imaging (T2WI). ASPS was partial, with rich tortuous flow voids, or “line-like” low signal septa. The essence of the mass was heterogeneous enhancement. The 1H-MRS showed a slight choline peak at 3.2 ppm.
Conclusion?The well-circumscribed mass and blood voids, combined with “line-like” low signals play a significant role in diagnosis. The choline peak and the other signs may be auxiliary diagnoses.
