[False-positive findings of 67-gallium scintigraphy in staging/restaging of malignant lymphoma].
Gallium scintigraphy has been an established method for the diagnosis of malignant lymphomas for some years. If properly interpreted, the value of the method is not necessarily reduced by the lack of tumour specificity and the well known property of 67Ga to accumulate in inflammatory and granulomatous conditions. A retrospective analysis of 123 patients with malignant lymphomas showed false positive 67Ga scintigrams in 7%. These cases demonstrate the spectrum of possible errors. 'False positives' were all those localised areas of uptake which were due to some pathological condition which was not lymphomatous. All the positive gallium findings could be elucidated by clinical, radiological and histological investigations.
