ABSTRACT

Objetivo: Estudiar el valor del SPECT cerebral en el diagnóstico y control evolutivo del compromiso del SNC en las enfermedades colágenovasculares (ECV) con sintomatología neuropsiquiátrica (SNP). Materiales y métodos: Se analizaron retrospectivamente 31 pacientes consecutivos portadores de ECV con SNP evaluados mediante SPECT cerebral con 99mTc-ECD y mapas estadísticos de superficie cortical. Veintiuno de ellos presentaban LES y 6 una enfermedad de Behçet. A 18 pacientes se efectuó además TC, a 8 RM y a 10 estudio neuropsicológico (ENP). Seis pacientes se realizaron SPECT de control. Resultados: Veintiocho pacientes presentaron SPECT patológico. La TC fue anormal en sólo 3/18 (sensibilidad 90,3 por ciento vs. 16,7 por ciento; p<0,001). La RM mostró alteraciones en 5/8 pacientes y el ENP en 7/10. Aunque todos estos pacientes presentaron SPECT patológico, los valores de sensibilidad no difirieron significativamente. Los pacientes con mayor SNP presentaron trastornos de perfusión más extensos (p<0,035). Los pacientes estudiados evolutivamente mostraron mejoría de los defectos con la respuesta al tratamiento y agravamiento con la reaparición de síntomas. Conclusiones: El SPECT cerebral presenta elevada sensibilidad en la detección del compromiso neuropsiquiátrico en las ECV. Su utilidad podría extenderse al control evolutivo y la evaluación de la respuesta terapéutica.


Objetive: To study the value of brain SPECT in the diagnosis and follow up of SNC involvement in systemic connective tissue diseases (SCTD) with neuropsychiatric symptoms (NPS). Materials and methods: We retrospectively analyzed 31 consecutive patients with SCTD presenting with NPS who underwent 99mTc-ECD SPECT and statistical surface maps. 21 patients had systemic lupus erythematosus and 3 had Behçet disease. Results were compared to those of CT (18/31), MRI (8/31) and neuropsychological examination (NPE). 6 patients had follow-up SPECT scans. Results: Twenty-eight patients had abnormal SPECT studies. CT was abnormal in 3/18 patients (sensitivity 90.3 percent vs. 16.7 percent; p<0.001). MRI showed alterations in 5/8 patients and NPE in 7/10. Although all these patients presented abnormal SPECT scans, sensitivity values were not statistically different. Patients with major NPS presented more extensive perfusion defects (p<0.035). Patients with follow-up SPECT scans showed perfusion improvement with response to treatment and progression of the alterations when symptoms relapsed. Conclusion: Brain SPECT presents high sensitivity for the detection of neurological involvement in SCTD. SPECT usefulness may extend to follow-up and evaluation of response to treatment.
