“…In addition, TRUS is usually used to guide a biopsy to confirm the diagnosis (1). The imaging features of MRI, such as a large size, irregular margins and heterogeneity, are similar to those of TRUS (15,16). Besides that, it has an advantage in detecting metastatic lesions and revealing the adjacent structures (17).…”

Abstract. Prostate sarcoma is a rare malignancy with an extremely poor prognosis. The extremely low morbidity and atypical clinical symptoms contribute to a missed diagnosis. The typical features of prostate sarcoma in transrectal ultrasound (US) and magnetic resonance imaging, such as a markedly enlarged volume and irregular prostatic contours, cannot usually be found until dysuria or even uroschesis occurs, and may then be too late to treat. However, there appears to no specific tumor marker for the disease in the serum. The present study reports a case of a young male patient who was diagnosed with prostate rhabdomyosarcoma. This was, to the best of our knowledge, the first case of this diagnosis using contrast-enhanced US (CEUS) when the symptoms were not severe. In this case, the intralesional non-enhancement areas and rim-like hyper-enhancement around the lesion were considered to be the main CEUS features of prostate rhabdomyosarcoma. The present study also reviews the associated literature.

“…Most patients with prostatic sarcoma, including PSS, present with symptoms of urethral obstruction (1-3, 5, 6), as in the present case. The mass effect of the tumor, mainly located in the central gland, probably caused the early onset of symptoms (17). In previous reports on PSS, age at diagnosis has ranged from 19 to 86 years (mean, 48 years) (1-5, 7-16).…”

MRI Appearance of Prostatic Stromal Sarcoma in a Young Adult

et al. 2011

Prostatic stromal sarcoma (PSS) is quite rare. Herein, we describe magnetic resonance imaging (MRI) features of a PSS identified in a 26-year-old man with dysuria and hematuria. MRI clearly depicted the extent and multinodular appearance of the tumor, which was mainly located in the central zone of the prostate. The tumor appeared as a heterogeneously signal-hyperintense mass with a pseudocapsule on T2-weighted imaging. Contrast-enhanced T1-weighted MRI showed necrotic portions in the gradually enhanced solid mass, and diffusion-weighted imaging permitted the accurate assessment of the local extent of the tumor. Thus, the appearance on MRI was quite different from that of adenocarcinoma of the prostate.
