REVIEW
Introdução: “Tumor haltere” é um termo utilizado para descrever tumores que se conectam e possuem duas ou mais regiões distintas, como o espaço intradural, epidural e paravertebral. A incidência desses tumores varia de 6% a 24% em grandes séries de estudos sobre tumores da medula espinhal. Os meningiomas espinhais em haltere são uma ocorrência rara, representando até 5% dos meningiomas espinhais com essa característica, e são relevantes no diagnóstico diferencial. Relato de caso: Paciente do sexo feminino, 55 anos, com cervicobraquialgia esquerda e tetraparesia progressiva, causada por meningioma na transição cervicotorácica. Após realização de exames e uso de medicação para alívio da dor, o paciente foi submetido a laminectomia, facetectomia, ressecção tumoral e correção do defeito da dura-máter com estabilização e artrodese posterior. A análise histopatológica evidenciou meningioma com marcadores de melhor prognóstico. A paciente teve recuperação sem complicações, com melhora completa dos sintomas e sem déficits motores ou sensoriais associados. Conclusão: O caso em questão é um tumor meningioma raro com características peculiares que causa sintomas limitantes. A investigação pré-operatória é essencial para definir o diagnóstico e planejar a cirurgia, o que pode resultar em melhora significativa na qualidade de vida do paciente e baixa chance de recidiva.
Introduction: “Dumbbell tumor” is a term used to describe tumors that connect and have two or more distinct regions, such as the intradural, epidural and paravertebral space. The incidence of these tumors ranges from 6% to 24% in large series of studies on spinal cord tumors. Dumbbell spinal meningiomas are a rare occurrence, accounting for up to 5% of spinal meningiomas with this feature, and are relevant in the differential diagnosis. Case report: Female patient, 55 years old, with left cervicobrachialgia and progressive tetraparesis, caused by meningioma in the cervicothoracic transition. After performing tests and using medication for pain relief, the patient underwent laminectomy, facetectomy, tumor resection and correction of the dura mater defect with stabilization and posterior arthrodesis. Histopathological analysis showed a meningioma with markers of better prognosis. The patient had an uncomplicated recovery, with complete improvement of symptoms and no associated motor or sensory deficits. Conclusion: The case in question is a rare meningioma tumor with peculiar characteristics that caused limiting symptoms. A preoperative investigation is essential to define the diagnosis and plan the surgery, which can result in a significant improvement in the patient’s quality of life and a low chance of recurrence.
