US of the pediatric female pelvis: a clinical perspective.

When investigating pelvic pathologic conditions in female pediatric patients, one needs to be aware of the developmental changes that take place around puberty. The prepubertal uterus is thin, with a fundus equal in size to the cervix. Owing to the hormonal stimulation of puberty, the uterus enlarges and the fundus becomes prominent. The ovaries are demonstrated with ultrasonography (US) at all ages. Ovarian volume increases after 6 years of age. Microcystic follicles are normally seen throughout childhood. US is the modality of choice for imaging the pediatric female pelvis. The main indications for pelvic US in the pediatric age group are pubertal precocity or pubertal delay, pelvic pain or pelvic masses, and ambiguous genitalia. Vaginal bleeding in the prepubertal child can be due to a vaginal foreign body, vaginal rhabdomyosarcoma, or precocious puberty. Common causes of primary amenorrhea in teenagers include gonadal dysgenesis (Turner syndrome) and müllerian (uterovaginal) anomalies. Pelvic pain or pelvic masses in pediatric patients can be due to ovarian torsion, hemorrhagic ovarian cyst, pelvic inflammatory disease, or ectopic pregnancy.

Diffuse arterial calcified elastopathy--a new cause of renovascular hypertension in children.

Diffuse arterial calcified elastopathy was observed in 6 pediatric patients presenting with severe renovascular hypertension. Renal ultrasonography showed a characteristic pattern, the dotted corticomedullary junction, related to the increased echogenicity of the interlobar and/or arcuate arteries. Superficial temporal artery biopsy demonstrated the presence and the extension of the calcifying process involving the elastic layers of the muscular arteries. This clinicopathological syndrome may be heterogeneous from an etiological point of view: etiologic investigations led to the diagnosis of pseudoxanthoma elasticum in 2 patients; no etiologic cause could be found in the others.

[Multiple chondroma affecting the spine: spondylo-enchondroplasia and other forms (author's transl)].

When reviewing the published literature on constitutional bone diseases, for inclusion in a data-processing system, the authors discovered six cases of enchondroplasia affecting the spine. Similar observations have been reported under the name of spondylo-enchondroplasia. Radiological signs and genetic information suggest that this group of affections is a heterogenous one. Vertebral lesions vary greatly in extent, reaching in some case the level of a spheno-occipital synchondrosis.
