Summary
Adult prostate sarcoma presents as large, heterogeneous masses on imaging, often causing urinary obstruction. Key features include rapid, avid enhancement and increased choline:citrate ratios on magnetic resonance spectroscopy.
Area of Science:
- Urology
- Radiology
- Oncology
Background:
- Prostate sarcoma is a rare and aggressive malignancy in adults.
- Understanding its imaging characteristics is crucial for diagnosis and management.
Purpose of the Study:
- To describe the imaging features of adult prostate sarcoma.
- To correlate these imaging findings with clinical and pathological data.
Main Methods:
- Retrospective analysis of radiological data from seven adult male patients with pathologically confirmed prostate sarcoma.
- Correlation of imaging features with clinical and pathological findings.
Main Results:
- Mean patient age was 45.8 years; mean PSA was 1.59 ng/ml.
- Common imaging findings included large, heterogeneous masses with cystic areas and avid enhancement on CT and MRI.
- Leiomyosarcomas (n=5) and rhabdomyosarcomas (n=2) were identified. Clinical presentation often involved urinary obstruction.
Conclusions:
- Adult prostate sarcoma typically appears as a large, heterogeneous, hypervascular mass on CT and MRI.
- Magnetic resonance spectroscopy may show an elevated choline:citrate ratio.
- Clinical symptoms are primarily related to local mass effect and invasion.
