Full history/Diagnosis is available below
41 year old man with prior resection of a right adrenal
pheochromocytoma 5 years ago. Now the patient
has elevated catecholamines and a low attenuation
lesion in the posterior segment of the right hepatic
Intense uptake is seen in a focus within the liver,
corresponding to the lesion seen on the CT examination.
No additional abnormal foci were identified.
At surgery, the liver lesion was confirmed to be
metastatic pheochromocytoma. However, there were
also small peritoneal metastases not visualized on
this I-131 MIBG scintigraphy. It is possible that
they would have been evident on a higher resolution
I-123 MIBG study; however the I-123 version of this
tracer was not commercially available at the time of
this study in the mid 1990's.
