RESUMO
BACKGROUND: Neurocysticercosis (NCC) is the most common parasitic infection involving the central nervous system in endemic areas. Notably, spinal involvement occurs in only 0.7%-3% of patients. CASE DESCRIPTION: A 58-year-old female presented with progressive spinal cord compression attributed to multiple cystic intradural extramedullary thoracic lesions. She underwent laminectomy at two separate thoracic levels; this involved excision of the upper T4-T6, and just exploration of the lower T9-T11 lesions. One year postoperatively, she exhibited a residual paraparesis. CONCLUSION: Spinal NCC must be considered among the differential diagnostic considerations for patients presenting with spinal intramedullary or subarachnoid/extramedullary cystic lesions. Although they are typically found in endemic regions, those who have traveled to these locations are also susceptible. Even though it is considered a benign condition, spinal NCC may cause permanent and irreversible neurological damage. Public health policies should, therefore, be developed to help control the spread and transmission of NCC.
RESUMO
OBJECTIVE: To present a retrospective study from patients with spinal cysticercosis (SC), diagnosed within the last 30 years in Mexican and Indian neurological referral centers. METHODS: This is a retrospective and comparative study of the clinical and radiological profile between Mexican and Indian patients with spinal neurocysticercosis during a 30-year period and a review of the literature during the same period. RESULTS: Twenty-seven SC patients were included: 19 from Mexico and 8 from India. SC presented predominantly with motor symptoms (21/27 patients): paraparesis and paraplegia were the most common signs; one-third of patients presented sphincter dysfunction. Imaging studies showed that parasites in vesicular stage were more frequent in patients from Mexico, while degenerative stages predominated in India. Association of subarachnoid cysticerci and hydrocephalus was observed only in Mexican patients. CONCLUSIONS: Despite the limitations of this study, the collected information supports the existence of differences in the clinical and radiological traits of SC patients between Asian and Latin-American hospitals. The possible biological factors that may underlie these differences are discussed.
