The authors reviewed the prenatal (11 infants) and postnatal (17 infants) sonograms and the clinical, surgical, and pathologic findings in 17 infants with an ovarian cyst to determine the sonographic features and natural history of neonatal ovarian cysts. An uncomplicated cyst (nontwisted, nonhemorrhagic) was completely anechoic and the cyst wall was(More)
The uterus in the neonate is prominent and readily identified on ultrasonography (US). The neonatal uterus is larger than the prepubertal uterus as a result of residual stimulation from maternal hormones. The uterus was visualized in 31 of 35 (89%) infant girls examined with real-time US. Mean uterine length was 3.4 cm. The majority of the uteri were(More)
Ten immunosuppressed patients with right lower quadrant pain were examined by CT. Underlying conditions responsible for immunosuppression included acute myelogenous leukemia (n = 2), acute lymphocytic leukemia (n = 2), aplastic anemia (n = 2), AIDS (n = 3), and cystic fibrosis combined with prolonged steroid therapy for bronchospasm (n = 1). CT suggested(More)
The sonographic findings in a patient with typhlitis are presented. Sonography showed a solid mass with a "target" sign in the right lower quadrant, continuous with the ascending colon. In addition to suggesting the diagnosis, sonography was helpful in the follow-up examination of the patient because it was able to assess the gradual decrease in the(More)
The sonographic findings in eight children with surgically proved cystic hygroma were reviewed and correlated with the pathologic specimens. Six tumors occurred in the neck, one occurred in the axilla, and one involved the soft tissues of the thigh, scrotum, and pelvis. A cystic hygroma characteristically appears as a multiloculated cystic mass with septa(More)
The Klippel-Trenaunay-Weber syndrome consists of cutaneous port wine hemangiomas, superficial venous varicosities, and soft tissue and bony hypertrophy of an extremity. We describe three patients with this syndrome with hypodense lesions in the spleen which in one case became isodense after bolus contrast CT. In one case ultrasound found numerous echopenic(More)
The sonographic examinations of four patients with simple ectopic ureters and 11 with ectopic ureteroceles were reviewed to determine distinguishing characteristics. Ectopic ureters, in cases of extreme dilatation and tortuosity, sometimes mimic multiseptated, cystic abdominal masses. However, the proximal portions of some severely dilated ureters are(More)
When an interlabial mass is seen on physical examination in a little girl, there is often confusion about its etiology, its implications, and what should be done next. Five common interlabial masses, which superficially are strikingly similar, include a prolapsed ectopic ureterocele, a prolapsed urethra, a paraurethral cyst, hydro-(metro)colpos, and(More)
