Biópsia estereotáxica para linfomas primários do sistema nervoso central

Stereotactic biopsy for primary lymphomas of the central nervous system

Resumos

Os linfomas primários do SNC são raros, mas sua incidência tem aumentado nos últimos anos, Estes tumores frequentemente se localizam nos gânglios da base e tálamo ou se apresentam de forma multifocal. O tratamento atual para eles é a radioterapia, associada ou não a quimioterapia. Devido à sua extremamente baixa morbidade, a biópsia estereo-táxica é o método ideal para determinar o diagnóstico histológico em pacientes com suspeita de linfomas do SNC. Os autores apresentam estudo de 49 casos de linfomas primários do SNC, diagnosticado por biópsia estereotáxica.

Primary lymphomas of the CNS are rare. However the incidence of these lesions has increased recently. These tumors are often situated in the thalamus and basal ganglia, but can be multifocal. The treatment for primary CNS lymphoma is radiotherapy alone or in association with chemotherapy. Because the associated morbidity is very low stereotactic biopsy is an ideal method for determining the histologic diagnosis in patients with suspected CNS lymphoma. The authors present a study of 49 patients with primary CNS lymphomas in which a stereotactic biopsy was performed.

SUMMARY

Primary lymphomas of the CNS are rare. However the incidence of these lesions has increased recently. These tumors are often situated in the thalamus and basal ganglia, but can be multifocal. The treatment for primary CNS lymphoma is radiotherapy alone or in association with chemotherapy. Because the associated morbidity is very low stereotactic biopsy is an ideal method for determining the histologic diagnosis in patients with suspected CNS lymphoma. The authors present a study of 49 patients with primary CNS lymphomas in which a stereotactic biopsy was performed.

Key words: CNS lymphomas, biopsy, stereotaxy, intracranial tumors.
