An instructive false diagnosis: steroid-induced complete remission of a CNS tumor--probably lymphoma.
1998
In recent years the incidence of primary cerebral lymphomas has increased. Diagnosis by imaging techniques (CCT, angiography MRT) and stereotactic biopsy are considered as reliable diagnostic tools. Therapeutically a combination of radio-, steroid- and chemotherapy is recommended. We report a case of space-occupying CNS lesion in which the radiopaque enhancing process completely disappeared after biopsy and steroid therapy. A year later the tumor recurred on the other side and again regressed after steroid therapy. The first biopsy showed signs of a papillar tumor, so a choroid plexus papilloma was suspected. On examination of the treatment history, however, this diagnosis had to be revised. A primary CNS lymphoma seems most probable. The phenomenon of a tumor remission under steroid administration and the problems related to the differential diagnosis are discussed.
