ABSTRACT

OBJECTIVE:

The purpose of this paper was to investigate the role of two three-dimensional magnetic resonance (MRI) sequences enhanced spoiled gradient recalled echo (SPGR), and fast imaging employing steady-state acquisition (FIESTA) in the evaluation of intraventricular neurocysticercosis cysts and scolices.

METHOD:

Seven neurocysticercosis patients suspected of presenting intraventricular lesions were evaluated by magnetic resonance imaging using enhanced SPGR, and FIESTA.

RESULTS:

Enhanced SPGR detected eight cystic lesions, with scolices in four. Contrast enhancement was observed in three cysts. FIESTA also detected eight cystic lesions with the presence of scolices in seven of those cystic lesions. Four patients presented parenchymal involvement, while the remaining three presented the racemose form.

CONCLUSION:

FIESTA and SPGR are sequences that can detect intraventricular cysts of neurocysticercosis, and FIESTA also is good for the detection of the scolex. Considering this information we suggest that FIESTA and SPGR should be included in the MRI protocol for the investigation of intraventricular neurocysticercosis.
RESUMO

OBJETIVO:

O objetivo deste trabalho foi investigar o papel de duas sequências de ressonância magnética (RM) volumétricas tridimensionais spoiled gradient recalled echo (SPGR) pós-contraste e fast imaging employing steady-state acquisition (FIESTA) na avaliação de cistos e escólex na neurocisticercose intraventricular.

MÉTODO:

Sete pacientes suspeitos de neurocisticercose intraventricular foram avaliados pela ressonância magnética com SPGR pós-contraste e FIESTA.

RESULTADOS:

SPGR pós-contraste evidenciou oito lesões císticas com presença de escólex em quatro. Realce foi observado em três destes cistos. FIESTA também detectou oito lesões císticas, com presença de escólex em sete destas lesões. Envolvimento do parênquima cerebral foi observado em quatro pacientes e forma racemosa em três.

CONCLUSÃO:

FIESTA e SPGR são sequências que permitem a detecção de cistos intraventriculares de neurocisticercose e FIESTA é uma boa sequência para a detecção de escólex. Considerando estes achados nós sugerimos que estas sequências (FIESTA e SPGR) devam ser incluídas no protocolo de RM na investigação de neurocisticercose intraventricular.
