Correct Answer � C
Explanation

Ans. C. Metastatic neuroblastoma
Raccoon eyes depicted on the first image and mass arising next to the right kidney along with a retro-orbital metastatic lesion shown in the second image on CT scan is highly suggestive of neuroblastoma.
Though retinoblastoma is the most common orbital malignancy, but an associated renal mass would not be explained RB, orbital cellulitis, and Rhabdomyosarcoma.
