BACKGROUND: @entity1636 ( @entity1636 ), a @entity5 that is rare among @entity1 , causes clinically evident hormonal disturbances. Imaging methods are used to stage disease and to plan surgical resection. OBJECTIVE: To describe the findings of the various imaging methods used to evaluate @entity1636 . MATERIALS AND METHODS: We reviewed the records of ten consecutive @entity1 (mean age, 8.1 years) who presented from 1987 to 1998 with @entity1636 . All @entity1 underwent computed tomography (CT) scanning; five underwent magnetic resonance (MR) imaging; four underwent ultrasonography (US); and eight underwent radionuclide bone scans. RESULTS: Seven @entity1 presented with signs of hormonally functional @entity5 . Typical imaging findings consisted of a large, well-defined suprarenal @entity5 , containing @entity730 (seven @entity1 ) with a thin capsule and central @entity39 or @entity548 (six @entity1 ). The inferior vena cava (IVC) was compressed by @entity5 in three @entity1 , and ultrasonography demonstrated invasion of the IVC wall in one of these. Three @entity1 ' bone scans showed that the @entity5 took up radioactive tracer. Spread to lungs or liver or both was demonstrated in six @entity1 . CONCLUSIONS: CT, US and MR imaging are effective methods of imaging the @entity5 . Chest CT and bone scintigraphy should be performed to detect metastases. The presence of a thin @entity5 capsule, a stellate central zone of @entity39 , and evidence of hormonal function help distinguish @entity1636 from @entity521 .
