Short-Term CT and MR Changes in Brain Tumors Following 125I Interstitial Irradiation

Abstract: The behavior of cerebral tumors and their appearance on CT and MR images after interstitial irradiation seem to be variable. Decrease in tumor size may take place at different intervals after therapy. Brachytherapy of tumors with a diameter of > 4 cm may produce space-occupying radionecrosis.

“…The time course in which we see these imaging effects was similar to that seen for central nervous system tumors treated with radiosurgery or interstitial brachytherapy (20)(21)(22). For example, Moringlane et al (22) noted that a ring-like signal on T 1 -positive contrast images developed as early as 1 month in most of their glioma patients treated with interstitial 125 I. This timing is very consistent with our own observations after GliaSite treatment.…”

“…Given that GliaSite treatment often treats the adjoining resection cavity surface to a high radiation dose, our findings are consistent with the T 1 -enhancing lesions we observed as being a type of pseudoprogression that does not signify disease recurrence. The time course in which we see these imaging effects was similar to that seen for central nervous system tumors treated with radiosurgery or interstitial brachytherapy (20)(21)(22). For example, Moringlane et al (22) noted that a ring-like signal on T 1 -positive contrast images developed as early as 1 month in most of their glioma patients treated with interstitial 125 I.…”

“…Even more striking on T 1 -weighted images after administering gadolinium contrast material, than with CT. Numerous papers refer to the radiological lesions after Gamma Knife surgery or interstitial irradiation [2,15,18,22,24,31]. The reactive ring is believed to consist of dilated and proliferating vessels.…”
