Primary renal neuroblastoma in adults

A 79-year-old woman was admitted to the hospital with a closed intertrochanteric femoral neck fracture after a fall and underwent dynamic hip screw fixation. Postoperatively, she developed painless hematuria but was hemodynamically stable. She had no significant medical history, apart from hypertension, which had been managed with antihypertensive medications for the previous 20 years. Her blood test and urine cytology results did not show any obvious abnormality. However, computed tomography of the abdomen and pelvis showed an enhancing mass measuring 5.4 x 6.1x 6.0 cm in the lower pole of the left kidney . She underwent additional staging examinations with computed tomography of the chest and a bone scan, the findings of which were unremarkable.
