Scintigraphy in lymphomas and leukemia of the brain.

Scintigraphy with 99mTc-pertechnetate made it possible to detect focal brain lesions in 4 patients with primary malignant lymphomas of the brain, one patient with CNS involvement with lymphatic immunoblastoma, one patient with Sézary syndrome (mycosis fungoides and T cell leukemia) and one child with a space occupying infiltration of myeloblastic leukemia. The scintigraphic results were verified by morphological data from biopsy or autopsy.
