ABSTRACT

An account is given of the results observed with I-131 MIBG scintigraphy in four patients (1 bladder pheochromocytoma, 3 neuroblastomas) chosen on account of their particular clinical and diagnostic interest from a series of 41 apudoma patients examined by means of this technique. In the first patient, the unusual site of the tumor in the posterior wall of the bladder meant that its detection by I-131 MIBG was only possible after catheterization of the bladder. In the second patient, uptake in the metastasis was only evident after removal of the primary tumor. In the third patient, the scintiscan revealed several metastases (some in bone) not detected by CT. In the fourth patient (congenital neuroblastoma), enhanced uptake accompanied the appearance of high plasma catecholamine and urinary vanillylhandelic acid values, suggesting a functional switch from a nonsecreting to a secreting form. a supplementary In-111 DTPA-Octreotide (OCT) scintiscan of this patient demonstrated the presence of somatostatin receptors on the neuroblasts. Thus, this examination would seem particularly useful for the differentiation of nonsecreting neuroblastomas. Its employment in assessment of the therapeutic capacity of OCT itself is also suggested.
