Transrectal ultrasound in the evaluation of rhabdomyosarcoma involving the prostate.
OBJECTIVE
To evaluate transrectal ultrasound as a means of diagnosis and of monitoring patients with rhabdomyosarcoma involving the prostate.


METHODS
Serial transrectal ultrasonography was utilized to evaluate prostatic rhabdomyosarcoma in three patients.


RESULTS
Unlike prostatic adenocarcinoma and transitional cell carcinoma involving the prostate, which are predominantly hypoechoic, the echogenicity of rhabdomyosarcoma is similar to that of the normal prostate. Transrectal ultrasound provided a simple means of monitoring prostate size and sampling tissue in these patients.


CONCLUSIONS
Transrectal ultrasound imaging can be useful in both diagnosis and evaluation of treatment response as well as provide easy access for biopsies in patients with rhabdomyosarcoma involving the prostate.
