[Contribution of ultrasonography to the study of retroperitoneal tumors in children (author's transl)]. 1982

L Cadier, and B Broussin, and A Calabet, and P Baudain, and F Diard

Ultrasonography investigations of retroperitoneal tumors in children were conducted in 25 cases: 11 nephroblastomas, 11 neuroblastomas, 2 ganglioneuromas, and 1 rhabdomyosarcoma. Ultrasonographic exploration of such tumors should include analysis of the mass: echostructure, limits, interfaces and dimensions, and analysis of its extension. The latter should determine the position in relation to the median line, the condition of the large vessels (inferior vena cava and aorta), the homolateral renal cavities and the contralateral kidney, and the presence or absence of glandular spread and hepatic metastases. The semiology of each of these elements is described and discussed, to determine their individual diagnostic value.

UI MeSH Term Description Entries

D009396 Wilms Tumor A malignant kidney tumor, caused by the uncontrolled multiplication of renal stem (blastemal), stromal (STROMAL CELLS), and epithelial (EPITHELIAL CELLS) elements. However, not all three are present in every case. Several genes or chromosomal areas have been associated with Wilms tumor which is usually found in childhood as a firm lump in a child's side or ABDOMEN.

D009447 Neuroblastoma A common neoplasm of early childhood arising from neural crest cells in the sympathetic nervous system, and characterized by diverse clinical behavior, ranging from spontaneous remission to rapid metastatic progression and death. This tumor is the most common intraabdominal malignancy of childhood, but it may also arise from thorax, neck, or rarely occur in the central nervous system. Histologic features include uniform round cells with hyperchromatic nuclei arranged in nests and separated by fibrovascular septa. Neuroblastomas may be associated with the opsoclonus-myoclonus syndrome.

D005260 Female Females
D005729 Ganglioneuroma A benign neoplasm that usually arises from the sympathetic trunk in the mediastinum. Histologic features include spindle cell proliferation (resembling a neurofibroma) and the presence of large ganglion cells. The tumor may present clinically with HORNER SYNDROME or diarrhea due to ectopic production of vasoactive intestinal peptide.
