Abstract:
:The diagnosis of Wilms' tumor is usually made by excretory urography after the patient presents with an abdominal mass. A diagnosis prior to the appearance of an obvious mass might result in an improved cure rate and less morbid therapy. The three cases described illustrate the difficulty in making an earlier diagnosis since pyelograms were "normal" prior to detection of the abdominal mass.

杂志文章abstract:BACKGROUND:Subglottic haemangioma causes progressive and life-threatening stridor, typically manifesting at age 2-3 months. Standard diagnosis is by laryngoscopy. Larynx sonography is rarely used but allows assessment of the presence and extension of a mass that impinges on the subglottic airway. The additional use of ...
