Imaging the pediatric prostate.

The prostate gland is not often the target of imaging in children but may be imaged during investigation of symptoms related to the lower genitourinary tract such as hematuria, urinary retention, dysuria, and incontinence or during an evaluation for suspected congenital anomalies. Ultrasound and voiding cystourethrography are useful for initial evaluation of congenital and neoplastic disorders of the prostate. MR imaging and CT are useful in delineating more detailed anatomy before surgical planning and in determining the organ of origin in a patient who has a large pelvic mass.

Desmoplastic small round cell tumor in the abdomen and pelvis: report of CT findings in 11 affected children and young adults.

OBJECTIVE: Our objective was to evaluate the CT features of desmoplastic small round cell tumor (DSRCT) of the abdomen and pelvis in pediatric and young adult patients. CONCLUSION: Characteristic CT features of DSRCT include bulky intraabdominal soft-tissue masses that involve omental and serosal surfaces, without a distinct organ of origin; solid, dominant, heterogeneous pelvic masses in the retrovesical or rectouterine spaces; and concurrent metastases, common at the time of diagnosis, particularly those involving lymph nodes and liver.

The utility of ultrasound site selection for pediatric percutaneous liver biopsy.

BACKGROUND: The site for percutaneous liver biopsy is determined by physical examination and anatomic landmarks. The authors compared physical examination with ultrasound examination to determine liver location, size, and an optimal biopsy site. METHODS: A pediatric gastroenterology fellow or attending gastroenterologist initially selected a biopsy site by physical examination. An ultrasonographer performed a limited ultrasound examination to evaluate this site. RESULTS: Sixty biopsy sites from 58 patients were evaluated. Forty-six patients had no previous liver surgery. Two patients had had a Kasai procedure. Ten patients had had orthotopic liver transplantation. The mean age of the patients was 11.1 +/- 7.6 years. Ultrasonography detected the following potential complications of percutaneous biopsy at the site determined by physical examination: insufficient liver (7 of 15, 47.0%), diaphragm injury (4 of 15, 27.0%), bowel perforation (2 of 15, 13.0%), kidney laceration (1 of 15, 7.0%), and large blood vessel laceration (1 of 15, 7.0%). These ultrasound findings directed a change in biopsy site for 15 (25.0%) physical examination sites. Major biopsy complications were rare (1.7%). CONCLUSION: Ultrasound examination resulted in a location change to a more optimal site in 25.0% of the sites determined by physical examination. Ultrasound determination of the biopsy site should be considered before pediatric percutaneous liver biopsy.
