Figure 2. Contrast-enhanced abdominal CT scan showing a 3.5 cm, heterogenous left adrenal mass.
Figure 3. Sectioned surface of the left adrenal gland showing the tumor surrounded by a thin yellow rim of residual adrenocortical tissue.

Paraneoplastic (Neuroblastoma) Opsocolonus
Opsoclonus herald sign 2-3%
Mean age at onset 16 years
Youngest 4 months of age
Older than 2 years in only 13%
Mediastinal tumor in 49-61%
Tumor found within 3 months in 60%
Rarely associated with elevated catecholamines (VMA, HVA metabolites)
Anti-neurofilament protein antibodies (M V 210 K) ± in sera
Paraneoplastic (Neuroblastoma) Opsocolonus
Survival rate 90% two-year c.f. 30-34% other neuroblastoma cases
Tumor removal may decrease, have no effect or exacerbate opsoclonus
Spontaneous resolution may take months or years
