“…3). This imaging feature of prostate sarcomas has also been previously described in the literature and is best seen at the border with the pelvic fat on the superior and posterior aspects of the mass [ 9 , 11 , 12 ] . The pseudocapsule results from the interface formed between tumour that has extended beyond the prostate and the adjacent compressed periprostatic soft tissues.…”

Sarcomas of the prostate are rare tumours. Their clinicopathologic features are well described, however, the imaging features of these tumours have rarely been documented. The purpose of this article is to illustrate the imaging findings of prostate sarcomas, with an emphasis on their appearance on magnetic resonance imaging and to identify features that may help to differentiate them from the commoner prostate adenocarcinomas.

“…PSS may differ from a typical adenocarcinoma with respect to shape, vascularity on DCE-MRI, and signal intensity on T2-weighted imaging, thus reflecting tissue construction and cellular structure. Conversely, these PSS findings resemble those of leiomyosarcoma and rhabdomyosarcoma, which are a more common form of sarcoma involving the prostate (22,23). Furthermore, DWI clearly demonstrated both central gland and peripheral zone parts of the tumor as showing marked high signal intensity, suggesting the usefulness of this modality for determining the local extent of the lesion.…”

“…In one report, a well-defined pseudocapsule, evident on both T1-and T2-weighted sequences, has been described at the interface of the mass with adjacent fat (9). The enhancement pattern of rhabdomyosarcomas has been described as heterogeneous or speckled, corresponding to intratumoral septum-like structures seen at histopathological analysis (8,10).…”

We report the magentic resonance (MR) findings of sarcoma botryoides in two young pediatric patients with this tumor. There has been very little literature regarding the MR appearance of this subtype of rhabdomyosarcoma. In both cases, the tumor was vaginal in origin, as would be expected in this age group. We found areas of bright T2 signal within these lesions, intermixed with areas of lower T2-signal tissue, which showed considerable enhancement. These imaging findings are reflective of the histologic architecture of these lesions, which are composed of separate myxoid and subepithelial cellular zones. In both cases, the extent of the tumor and lack of local invasion or metastatic disease were confirmed surgically, and both patients have undergone multiple postoperative MR studies that have shown lack of residual, recurrent, or metastatic disease.
