| Case 1 Presentation |
|---|
Prior to this episode, he has been well, developing normally and growing along the 10th percentile for height and weight. He has had no recent infections or trauma and is receiving no medications.
On physical examination, his temperature is 99.0°F (37.2°C), heart rate is 104 beats/min, respiratory rate is 22 breaths/min, and blood pressure is 93/58 mm Hg. He appears cachectic and weighs 10.4 kg (5th percentile). His abdomen is grossly distended, dull to percussion, and not tender. A solid, firm mass encompasses the left flank, extending 4 cm past midline to the right. The superior and inferior edges cannot be discerned, and the liver and spleen cannot be distinguished as either separate from or part of the mass.
His white blood cell count is 17.0x103/mcL (17.0x109/L) with a normal differential count, Hgb is 11.3 g/dL (113 g/L), Hct is 36.1% (0.361), mean corpuscular volume is 76.1 fL, and platelet count is 653.0x103/mcL (653.0x109/L). Results of serum chemistries and hepatic function tests are normal except for a bicarbonate concentration of 17.0 mEq/L (17.0 mmol/L). C-reactive protein is elevated at 2.2 mg/dL (0.22 mg/dL). Urinalysis yields normal results.
An abdominal radiograph leads to additional imaging, but the final diagnosis is made only after a procedure.
