Paraspinal Neuroblastoma vs. Adrenal Gland Neuroblastoma
Left picture: From the coarse and irregular calcifications in the x-ray a retroperitoneal teratoma can be expected; in fact, a paraspinal neuroblastoma was present in this case. Right picture: The diagnosis in this 11-month-old infant is a neuroblastoma of the right adrenal gland with skull metastasis. The operative preparation shows multiple scattered calcifications corresponding to the multiple fine and wispy calcifications of the tumor x-rays, and which are pathognomonic for a retroperitoneal neuroblastoma, which is illustrated best by the third picture from the top.
Left picture: Lateral picture of a contrast enema in a girl just after infancy; the colon is displaced forward, and some relatively large, coarse calcifications are recognizable in the retroperitoeal space. Right picture: 11-month-old boy with a palpable mass in the right upper belly and a protrusion of the bulbi. In the IVU a displacement of the right kidney in a caudal direction is visible which is recognizable by the horizontal limits of the renal pelvis in comparison with the left side, and a mass cranially of the kidney with fine wispy calcifications. They are recognizable even better on a lateral skull x-ray in the fronto-parietal region which is shown in the second picture from the top. The incised preparation of a retroperitoneal tumor with the same diagnosis in another child in the third picture from the top shows countless punctated white scattered deposits.
