title: Unusual uptake and retention of I-123 IMP in brain tumors.
abstract: Ten patients with unusual uptake and retention of I-123 IMP in their brain tumors were studied. Of these ten patients, five had meningiomas and the remaining five had glioblastoma, malignant astrocytoma, malignant lymphoma, metastatic brain tumor, and cellular blue nevus. Six tumors (five meningiomas and the glioblastoma) showed short term retention of I-123 IMP. Three tumors (the malignant astrocytoma, the malignant lymphoma, and the metastatic brain tumor) showed a delayed increase of radioactivity and the cellular blue nevus showed a gradual increase and long term retention of the tracer.
