Juvenile granulosa cell tumor in a 13-year-old girl with enchondromatosis (Ollier's disease): a case report.

Juvenile granulosa cell tumor (JGCT) of the ovary has been reported to occur rarely in conjunction with Ollier's disease. We report a case of a 13-year-old girl who was noted to have a large abdominal mass at the time of excision of a symptomatic enchondroma of the right femur. Subsequent laparotomy at a tertiary care children's medical center identified a JGCT confined to the right ovary. Review of the literature reveals eight previous cases of JGCT in patients with Ollier's disease. The pathophysiology and possible common causes of both disorders is discussed.

Autopsy, radiographic, and prenatal ultrasonographic examination of a stillborn fetus with femoral facial syndrome.

Femoral facial syndrome (FFS) is comprised of cleft palate, micrognathia, short or absent femora, and vertebral and genitourinary malformations. We report on a stillborn fetus with FFS delivered to a mother with gestational diabetes. Prenatal ultrasound examination showed abnormalities at 21 weeks of gestation; prior ultrasound findings were interpreted as normal. Long bone histology showed disorganization of the growth plate with a relative decrease in cartilaginous matrix and vacuolization and binucleation of the chondrocytes.

Radiographic appearance of the pars nuda urethrae in the voiding urethrogram.

The pars nuda is the most anterior segment of the male membranous urethra, extending from the urogenital diaphragm to the urethral bulb. It differs from adjacent urethral segments in being incompletely supported by corpus cavernosum and musculature. Usually, this part of the urethra is difficult to distinguish in a voiding urethrogram. Occasionally, however, it may stand out clearly in certain phases of urethral muscular activity, resulting in a roentgen picture which may mimic an abnormality.

Congenital double pylorus with accessory pyloric channel communicating with an intraluminal duplication cyst of the duodenum.

Congenital double pylorus is a rare anomaly in which two pyloric openings connect the antrum of the stomach to the duodenal bulb. We report an unusual case of congenital double pylorus in which one of the channels led to an intraluminal cystic duplication of the duodenal bulb. An embryologic relation between congenital double pylorus and antroduodenal duplications is suggested.

Diagnosis of synovial cysts in children by magnetic resonance imaging.

Synovial cysts complicating inflammatory joint disease are less common in children than in adults. They may present at sites distant from the joint and be mistaken for other conditions. We present 2 children in whom the diagnosis was made using magnetic resonance imaging at medium field strength (0.35 tesla).

Ureteropelvic junction obstruction presenting with recurrent abdominal pain: diagnosis by ultrasound.

Three cases of ureteropelvic junction obstruction are presented in which the only symptom was recurrent abdominal pain. Results of physical examination and urinalysis were normal. Ultrasound established the correct diagnosis in the two patients in whom it was performed. Because it is safe, involves no radiation exposure, and is useful in evaluating the gallbladder, pancrease, and liver, as well as both kidneys, abdominal ultrasound should be performed prior to contrast radiography in the evaluation of children with recurrent abdominal pain.

Cranial sonography: anatomic and pathological correlation.

Through the acoustic window of the anterior fontanelle, coronal and parasagittal sonograms of the infant and premature neonate are easily obtained. Supplementary axial images are obtained through the lateral skull vault. The normal anatomy of axial, coronal, and sagittal sonograms will be demonstrated by correlating normal infant brain images with cadaver brain slices at similar levels. The relevant anatomical structures will be identified and labeled. Pathological entities, i.e., intracerebral hemorrhage, brain tumors, arteriovenous malformations, hydrocephalus, and congenital malformation syndromes will be included. Neonatal ultrasound is an inexpensive, innocuous, and noninvasive technique for examining the brain of the newborn infant. It does not require sedation and can be performed either within the radiology department or in the newborn intensive care unit.

Sonographic recognition of multiple cystic encephalomalacia.

Multiple cysts in both hemispheres were detected in four children under 1 year of age by real-time sonographic sector scanning. These cysts, typical of multiple cystic encephalomalacia, followed viral encephalitis in two, bacterial meningitis in one, and bacterial meningitis superimposed on intracerebral hemorrhage in one. The diagnosis of multiple cystic encephalomalacia, which has a grave prognosis, is readily made with high-resolution real-time sonography.

Double aortic arch: an orifice projection using angled cineangiography.

Double aortic arches are usually shown angiographically by an injection of contrast in the aortic root with filming in the frontal (PA) and lateral projections. This is not completely satisfactory, however, as superimposition may mask the site of an associated atresia, which dictates the point at which the narrower arch should be divided. An angled view of the orifice of the ring, obtained in a six-week-old boy, showed the complete anatomy of the malformation.

Corrosive esophagitis in children. Assessment by the esophagogram.

The roentgenograms of 27 children aged 10 months to 13 years with endoscopically confirmed corrosive esophagitis were reviewed. The initial barium esophagogram showed 19 to have strictures. The length and irregularity of the strictures were recorded and related to the severity of the illness and the treatment required. In the remaining eight patients, the initial study gave normal results, but two were later shown to have developed strictures.

Neonatal pneumonia associated with medium-chain triglyceride feeding supplement.

The appearance of a similar pattern of multifocal pulmonary consolidation in four neonates receiving undiluted medium-chain triglyceride oil suggested a cause-and-effect relationship. This was supported by the demonstration in rabbits that the transtracheal injection of MCTO caused severe pneumonia. It is suggested that MCTO be mixed with formula before it is given to neonates.

Urography in the child who wets.

Most children who wet have no underlying structural abnormality and will not benefit from urography. However, several conditions may mimic simple enuresis, and in children with clinical clues that suggest these diagnoses, urography can be confirmatory. The urogram should be conducted so as to exclude an anatomic cause for wetting. This is likely in females in the presence of a duplex collecting system, a nonfunctioning kidney, marked vaginal reflux, or a widened interpublic distance. In the urogram of a child of either sex, a spinal anomaly should be sought.
