-Spinal cord compressing syndrome due to synovial cyst (SC) of the thoracic spine is a rare clinic condition. We report a case of SC located in the thoracic spine causing spastic paraparesis in a 14 yearold female patient. The SC was removed thoroughly by laminectomy. The patient had an excellent recovery. The etiological and therapeutic aspects are discussed.Key WoRdS: myelopathy, synovial cyst, spinal cord compressing, thoracic spine.Cisto sinovial da coluna torácica: relato de caso ReSUMo -Síndrome de compressão medular causada por cisto sinovial (CS) da coluna torácica é patologia rara e pouco descrita na literatura. descrevemos um caso de CS da coluna torácica causando paraparesia espástica em uma paciente de 14 anos de idade. o cisto foi removido através de laminectomia e a paciente apresentou uma excelente recuperação. discutimos os aspectos etiológicos e terapêuticos.PAlAvRAS-ChAve: mielopatia, cisto sinovial, compressão medular, coluna torácica. Synovial cysts (SC) of the spine are cystic dilatations of the synovial sheaths commonly found in the lumbar spine [1][2][3][4][5][6][7] , following by the cervical [8][9][10][11][12][13] and rarely in the thoracic spine 14-16 usually affecting patients over the fifth decade. These can cause myeloradiculopathy, depending on the level of occurrence due to compression of the spinal cord structure or the peripherical roots 2,3 . These cysts have intraspinal and extradural location and originate from the facet capsules caused by degeneration of the facet joints, being therefore known as synovial, juxtafacet, ganglion or ligamentum flavum cysts 14 . Incidentally, can be diagnosed during pain investigation located in the spine and/or myeloradicular symptoms; now they are more easily diagnosed through magnetic resonance imaging (MRI) 1 and by computerized tomography (CT)
18. The SC of the thoracic spine is infrequent and the world literature shows a shortage of documented cases.This fact collaborates with the aim of this study: presentation of a case of SC in a young patient, occurring in the thoracic spine and developing progressively compressive spine symptoms.
CASEA 14 years-old girl was admitted with a chief complain of weakness in the lower limbs which had started four months earlier. In the beginning she felt an intermittent weakness, mainly in the right, that interfered in the dance classe development. The weakness was progressive, followed by cramps, tingling and interfering in the gait. Moderate alteration of anal and vesical sphincter function was presented. The general examination showed good overall state. The patient was alert, lucid and guided, but with depressed humor. vital signs were normal. Absence of palpable ganglions was noticed. The cardio-respiratory system and the abdomen did not show any alteration during exam. Neurological exam presented: asymmetrical paraparesis (R>l); moderate hypertonia (R>l); increased deep tendon reflexes with clonus in the lower limbs. Bilateral Babinski sign being more evident in the right. Superficial hypoesth...
