Material and methods. A case of using computed tomography in a 19-month-old patient with inconclusive ultrasound findings and scintigraphy with I123-MIBG is presented. Computed tomography was performed with a bolus injection of a contrast agent. A lesion was revealed in the projection of the right adrenal gland, regarded as neuroblastoma (NB). Based on the data obtained, laparoscopic tumor-adrenalectomy with removal of the tumor was performed. In the control CT scan performed after surgery, additional formations in the right retroperitoneal space were not detected.

Results. In the case of negative or doubtful results of ultrasound examination and scintigraphy with I123-MIBG, CT scan with bolus injection of a contrast agent revealed an additional small lesion in the projection of the right adrenal gland. The data obtained predetermined the choice of treatment tactics. Control CT scan after laparoscopic surgery showed the absence of formation and risk factors.

Discussion. Computed tomography with a bolus injection of a contrast agent made it possible to accurately identify the mass of the right adrenal gland with a volume of 0.13 cm3, to choose an adequate treatment strategy and to monitor the surgical benefits.

Conclusion. The usage of contrast-enhanced computed tomography in the diagnostic algorithm made it possible to determine the treatment tactics and perform a minimally invasive operation with complete removal of the mass. Postoperative CT monitoring confirmed the absence of a mass lesion and risk factors IDRF.
