Fig 1: CT and MIBG scans and bone marrow aspirates at presentation. (A ) CT scan demonstrating right adrenal mass (open arrow, left panel ) with MIBG avidity (closed arrow, right panel ). (B ) Immunohistochemistry of right (left panel ) and left (right panel ) iliac bone marrow aspirates demonstrating large atypical cells (star ) and clumps of atypical cells (star ), consistent with neuroblastoma constituting less than 10% of the specimen. Scale bars represent 10 µm.
