The sonographic appearance of the hemorrhagic ovarian cyst in adolescents.

Pelvic sonography was performed on ten teenaged girls who were proven by surgery to have hemorrhagic ovarian cysts. Pathologically, four were follicular ovarian cysts, while three were corpus luteal cysts, and the exact nature of three was undetermined. At sonography, these masses had variable appearances, ranging from anechoic to moderately echoic with septa and thick walls. All these features are nonspecific and can be encountered in other adnexal masses. The changing sonographic appearance of the hemorrhagic ovarian cyst due to clot lysis is helpful in establishing the diagnosis, and was demonstrated in two cases. These ten cases are discussed, the varied sonographic appearances are described and a review of pertinent literature is included.

Sonography of scrotal masses in healed meconium peritonitis.

Although sonography is the procedure of choice in evaluating testicular masses in infants, x-ray examination can confirm the diagnosis of healed meconium peritonitis by showing scattered intra-abdominal as well as intrascrotal calcifications. Failure to include an abdominal radiograph early in the evaluation of 2 infants admitted with hard scrotal masses resulted in delayed diagnosis of healed meconium peritonitis. The clinical progression of meconium peritonitis involving the scrotum starts with soft hydroceles at birth and progresses, as the meconium calcifies, to hard "tumor-like" masses at age 4-5 weeks. This paper stresses the sonographic characteristics of meconium peritonitis in the scrotum and the need for confirming radiographs of the abdomen.

Sonographic evaluation of non-inflammatory neck masses in children.

A review of the sonographic findings in 17 children with non-inflammatory neck masses suggests that while ultrasound is nonspecific with regard to the differential diagnosis, it can show whether a mass is cystic, solid, or complex. Sonography is also useful in clarifying the anatomical extent of a lesion and involvement of underlying normal structures.

Nonobstructive hydrocolpos: sonographic appearance and differential diagnosis.

Hydrocolpos in the pediatric patient almost invariably occurs secondary to fluid distending the vaginal canal proximal to an obstructive lesion, usually an imperforate hymen. There are, however, other causes for fluid filling and sometimes markedly distending the vagina; many of these are not pathologic. Sonographically, fluid in the vaginal canal often has a confusing appearance and may be mistaken for a pathologic mass. Ways of differentiating hydrocolpos from other normal and abnormal pelvic fluid collections are described. Five adult patients are presented who showed a varied sonographic spectrum of nonobstructive hydrocolpos.

Sonography of vesical and perivesical abnormalities in children.

Pelvic sonograms of 40 children who had abnormalities related to the bladder and perivesical region were reviewed. The lesions detected were categorized into three groups, intramural, intravesical, and perivesical; in each category, conditions not related to vesical or perivesical anomalies that could mimic such anomalies were encountered. Real-time ultrasonography was most helpful in identifying ectopic ureteroceles. Aperistaltic loops of bowel were found to mimic perivesical cysts.

Observations on persistently dilated ureter after posterior urethral valve ablation.

The persistent ureteral dilatation frequently seen months or even years after posterior urethral valve ablation, continues to present a dilemma to the urologist. We have classified these dilated ureters into 3 types: (I) unobstructed with either an empty or filling bladder, (II) unobstructed with an empty bladder but obstructed with a filling bladder, and (III) obstructed with either an empty or filling bladder. The majority of ureters with persistent dilatation were found to be of the type II variety where appropriate treatment is not obvious. Classic ureteral tailoring and reimplantation offers little advantage since in such cases a narrower ureter is passed through a new hiatus in an otherwise unchanged bladder. When high renal pelvic pressures are found only with bladder filling, then consideration must be given to not only reconstructing the ureter but also to affecting the dynamics of the bladder and the large urinary output characteristically found in these patients.

Cryptococcal osteomyelitis. Report of a case amd a review of the literature.

A case is reported of isolated cryptococcal osteomyelitis in an 11-year-old girl without any detectable underlying disease. The patient was successfully treated for six weeks with intravenous amphotericin B and oral 5-flucytosine. There is only one other case of cryptococcal osteomyelitis reported in the English medical literature in a child. Over 50 per cent of individuals with this infection will have an underlying condition which may have predisposed them to acquiring this disease.

Pancreatitis, child abuse, and skeletal lesions.

A case of pancreatitis associated with trauma of child abuse is reported. Skeletal changes secondary to pancreatitis developed and the distribution of the bony lesions included both metaphyseal and epiphyseal growth centers. The coexistence of pancreatitis, child abuse, and subsequent skeletal lesions is again emphasized, as well as the unique occurrence of lesions in the epiphyseal centers.

Kayexalate: a new cause of neonatal bowel opacification.

Two cases of neonatal bowel opacification secondary to oral and rectal administration of Kayexalate (sodium polystyrene sulfonate) are presented. Abdominal radiographs of both infants showed a faint, homogeneous increase in density within the bowel lumen. The properties of Kayexalate and its possible interactions with the gastrointestinal tract are discussed. Kayexalate administration should be included in the differential diagnosis of bowel opacification.

Abdominal lipoblastomatosis: radiographic, echographic, and computed tomographic findings.

Two cases of lipoblastomatosis in infants are described. Radiography, ultrasonography, and computerized tomography showed well-defined soft-tissue densities embedded within large masses of adipose tissue. This appearance, which may be specific for lipoblastomatosis, correlated precisely with the pathologic appearance of lobules of immature adipose tissue surrounding masses of myxoid tissue.

Calcified portal vein thromboemboli in infants: radiography and ultrasonography.

Calcified portal vein thromboemboli (CPVT) in six neonates are reported. Three of the infants had multiple chromosomal abnormalities. Ultrasonography was performed in one patient to confirm the intrahepatic location of the calcification. CPVT, which are usually incidental observations on abdominal radiographs in neonates, should be considered in the differential diagnosis of calcifications limited to the hepatic area. These lesions are usually peripheral, and seem to be associated with multiple anomalies in infants. Ultrasonography is useful in demonstrating the intrahepatic and peripheral location of these calcifications.

The role of sonography in evaluating right upper quadrant disease in children.

Since 1974, grey scale sonography has been used with increasing frequency in evaluating abdominal masses in children. Because sonography is noninvasive and does not involve ionizing radiation, it is of particular value in the evaluation of pediatric patients. This paper focuses on right upper quadrant masses in children. The liver and gallbladder have been easy to image sonographically. It should be noted that sonography cannot accurately differentiate between benign and malignant lesions. The pancreas, previously a difficult organ to appreciate radiographically, can be visualized with both ultrasound and computerized tomography. Both history and physical examination are important to the sonographic evaluation of masses in children.
