dc.description.abstractFrom June, 1980, to August, 1983, 131 I MIBG scintiscans were performed in 353 patients with suspected pheochromocytomas. Extra-adrenal pheochromocytomas were identified in 15 of 18 patients who at operation were proven to have such tumors and normal adrenal glands. Conventional localization studies, often repeated, had failed to localize these tumors in nearly all cases. Nine of the extraadrenal pheochromocytomas were found within the middle mediastinum. This group of unique tumors required further specialized localization studies with augmented computed tomography (CT) scans for specific anatomical delineation. These complementary studies allowed for precise planning of surgical excision of the tumors, which required cardiopulmonary bypass in some patients. Extraadrenal pheochromocytomas were identified in a family with no other endocrinopathies. The tumors in 3 patients from 3 different generations all were perirenal and involved the vena cava. 131 I MIBG scintiscans detected metastatic lesions in 40 patients with malignant pheochromocytomas. Metastases were not readily demonstrated in 4 patients. The diagnosis of malignant and metastatic pheochromocytoma was first made by the scintiscan findings in 5 patients. 131 I MIBG scans were not false-positive in any cases and were falsenegative in 10.5% of 95 patients proven to have pheochromocytomas by biochemical evidence or operation. Ten patients have been treated for malignant pheochromocytomas with therapeutic doses of 131 I MIBG. Five patients have had objective responses with diminution in size of metastases or primary malignant tumor and a decrease in the secretion of catecholamines. This agent has been found to be of great value in detecting pheochromocytomas that often have defied all other means of localization. 131 I MIBG concentrates in most malignant pheochromocytomas, and preliminary results suggest that it will be very useful in the treatment of this disease. De juin 1980 à août 1983, 353 malades suspects d'être porteurs de phéochromocytomes ont été soumis à la scintigraphie à l'iode marqué: I 131 métaiodobenzylguanidine (I 131 MIBG). Des phéochromocytomes extra-surrénaliens ont été découverts chez 15 des 18 sujets suspects d'être porteurs de telles lésions extra-surrénaliennes, ce qui fut constaté lors de l'intervention qui démontra que les surrénales étaient normales. Les autres méthodes conventionnelles n'avaient pas permis de localiser ces tumeurs dans la majorité des cas. Neuf des phéochromocytomes extra-surrénaliens furent découverts dans la partie moyenne du médiastin. Ce groupe de tumeurs implique la mise en oeuvre de techniques particulières en plus du scanner pour localiser la tumeur. Ces explorations complémentaires permettent de planifier l'intervention chirurgicale qui peut nécessiter l'emploi d'une circulation extra-corporelle. Des phéochromocytomes extra-surrénaliens ont été découverts dans une famille qui ne présentait pas d'autres endocrinopathies. Les tumeurs chez 3 malades appartenant à 3 générations différentes siégeaient hors de la surrénale et intéressaient la veine cave. La scintigraphie à l'I 131 marqué a permis de découvrir des métastases chez 40 malades porteurs d'un phéochromocytome malin, mais fut en défaut dans 4 cas. Le diagnostic de phéochromocytome malin avec métastase fut porté initialement chez 5 malades. La scintigraphie ne se solda par aucun faux positif mais 10,5% de faux négatifs furent constatés chez 95 malades où la présence d'un phéochromocytome fut prouvée par les données biologiques ou opératoires. Dix malades atteints de phéochromocytomes malins ont été traités par l'I 131 marqué. Cinq d'entre eux accusèrent une diminution de volume de la tumeur et des métastases et une diminution de la sécrétion des catécholamines. L'iode marqué: I 131 méta-iodobenzylguanidine permet de déceler les phéochromocytomes qui échappent aux autres explorations. Le fait qu'il s'accumule électivement au niveau de la tumeur permet de penser qu'il pourra jouer un rôle actif dans le traitement de l'affection. El diagnóstico de feocromocitoma con frecuencia es más simple que establecer la localización anatómica del tumor, lo cual es difícil, especialmente cuando el feocromocitoma es maligno, extraadrenal o bilateral. Aproximadamente el 10% de los feocromocitomas se origina en tejido cromafino ubicado en algún lugar entre la base del cráneo y la vejiga. La tomografía computadorizada de tercera generación es extremadamente precisa en la localización de lesiones intra-adrenales, pero no es muy util en la identificación de feocromocitomas extra-adrenaleso metastásicos. Hasta muy recientemente no existía modalidad alguna capaz de proveer documentación anatómica y funcional del tumor con anterioridad a la intervención quirúrgica. La síntesis de la I 131 metayodo-benzilguanidina (I 131 MIBG) ha hecho posible obtener imágenes scintigráficas de feocromocitomas y de tejido cromafino hiperplásico.en_US
