Can lumbar hemorrhagic synovial cyst cause acute radicular compression? Case report / O cisto sinovial hemorrágico lombar pode causar compressão radicular aguda? Relato de caso

Lumbar synovial cysts are an uncommon cause of back pain and radiculopathy, usually manifesting with gradual onset of symptoms, secondary to involvement of the spinal canal. Rarely, intracyst hemorrhage occurs, and may acutely present as radicular - or even spinal cord - compression syndrome. Synovial cysts are generally associated with degenerative facets, although the pathogenesis has not been entirely established. We report a case of bleeding complication in a synovial cyst at L2-L3, adjacent to the right interfacet joint, causing acute pain and radiculopathy in a patient on anticoagulation therapy who required surgical resection.

Cistos sinoviais da coluna lombar são uma causa incomum de dor na coluna e radiculopatia, geralmente com evolução gradual dos sintomas, que são secundários ao comprometimento do canal vertebral. Raramente, há hemorragia intracística, que pode se manifestar de forma aguda com síndrome compressiva radicular ou mesmo medular. Habitualmente, os cistos sinoviais associam-se a doença degenerativa facetária, embora a patogênese não esteja completamente estabelecida. Relatamos aqui um caso em que uma complicação hemorrágica em um cisto sinovial no nível L2-L3, adjacente à interfacetária direita, causou dor lombar e radiculopatia em um paciente em terapia anticoagulante, sendo necessária a ressecção cirúrgica.

Case report. Atlantoaxial synovial cyst causing isolated unilateral hypoglossal nerve paralysis.

Cervical synovial cysts are rare entities that are, most of the time, asymptomatic. They can cause nerve root or spinal cord compression, especially when acute haemorrhage or a marked increase in size occurs. Isolated unilateral hypoglossal nerve paralysis caused by compression of its cisternal segment is also an extremely rare condition. We report the case of a 51-year-old woman who presented with dysarthria and tongue fasciculation. MRI revealed an atlantoaxial synovial cyst that extended cranially through the hypoglossal canal and compressed the fibres of the left XII nerve on its cisternal segment. To our knowledge, this is the first case report of XII nerve paralysis being caused by an atlantoaxial synovial cyst.

Compressão extrínseca de veia ilíaca externa e edema de membro inferior por cisto sinovial coxofemoral / Extrinsic compression of the external iliac vein and lower limb edema caused by hip joint synovial cyst / Extrinsic compression of the external iliac vein and lower limb edema caused by hip joint synovial cyst

A trombose venosa profunda (TVP) é uma freqüente causa de edema unilateral de membros inferiores. O cisto sinovial da articulação coxofemoral pode ser uma causa rara desse sintoma e deve ser considerado no diagnóstico diferencial. Apresentamos um caso clínico em que o eco-Doppler colorido revelou a presença de compressão extrínseca da veia ilíaca externa. A ressonância magnética demonstrou tratar-se de cisto sinovial como fator etiológico, confirmado pela ressecção cirúrgica.

Deep venous thrombosis frequently results in unilateral lower limb edema. A synovial cyst in the hip joint may be a rare cause of this symptom and should be considered in the differential diagnosis. We report on a case in which color-flow Doppler ultrasonography showed presence of extrinsic compression of the external iliac vein. Magnetic resonance imaging showed a synovial cyst as etiologic factor, confirmed by surgical excision.

Myelopathic presentation of cervical juxtafacet cyst: a case report.

STUDY DESIGN: Case report. OBJECTIVES: Discussion about the nature of the lesion, its various presentations, image characteristics, clinical features, surgical treatment, and patient outcome. SUMMARY OF BACKGROUND DATA: Juxtafacet cysts are uncommon intraspinal lesions most frequently found in the lumbar region. They usually originate as monoradicular compression syndrome mimicking disc herniation. In the cervical spine, they are rare and also have similar clinical features to intervertebral disc protrusion. However, the image findings are highly discriminative and often lead to accurate diagnosis. The cyst occupies a posterolateral position within the spinal canal, displacing the nerve root anteriorly. This situation is better seen in magnetic resonance imaging, but computed tomography scan and plain myelography also point to a diagnosis. The posterolateral site in the spinal canal can be accessed directly by a single-level laminectomy or hemilaminectomy. These are epidural lesions, usually cystic, attached to the facet joint and protruding into the intervertebral foramen. Recurrence after surgery is extremely rare and has only been reported in the lumbar spine. METHODS: In this article, we report the case of a male patient, 64 years of age, who presented with a progressive and severe myelopathy associated with multiple mononeuropathy, which delayed the diagnosis and treatment of the main neurologic condition, a cervical spinal compressive syndrome, proven to have originated as a juxtafacet cyst. The patient underwent complete surgical excision of the lesion. RESULTS AND CONCLUSIONS: The patient had good recovery of the myelopathy, and 6 months after surgery, he was able to walk. A follow-up of 2.5 years has not revealed any recurrence or new neurologic conditions.

Quistes sinoviales de columna lumbar: una causa de compresión radicular / Synovial cysts of the lumbar spine: a cause of radicular compression

Los quistes sinoviales (QS) de columna lumbar son lesiones infrecuentes pero deben considerarse frente a casos de compresión radicular. Existe controversia acerca de su patogenia y se describen múltiples opciones terapéuticas. Se presenta una serie clínica retrospectiva de siete pacientes tratados en un período de ocho años. En general fueron pacientes mayores de 60 años, con un cuadro de dolor radicular unilateral, que se presentó 3 meses antes del diagnótico. Sólo dos pacientes tuvieron déficit de la raíz correspodiente. Todos los QS se localizaron en el nivel L4-L5, realizándose hemilaminectomía y resección total del quiste. Seis casos tuvieron desaparición completa del dolor. Un paciente presentó sólo alivio moderado, constatándose espondilolistesis, por lo que fue sometido posteriormente a una fusión vertebral, mejorando su sintomatología. La cirugía es un tratamiento seguro y eficaz para la resolución de esta patología. La literatura acerca de esta importante patología fue revisada

Analysis of a large kindred with Blau syndrome for HLA, autoimmunity, and sarcoidosis.

OBJECTIVE: To determine whether HLA and autoimmunity contribute to the pathogenesis of Blau syndrome (familial granulomatous arthritis, uveitis, and rash) and evaluate whether this condition is related to sarcoidosis. DESIGN: Large family survey. SETTING: General community, Green Bay, Wis, and two tertiary care medical centers in Philadelphia, Pa. PARTICIPANTS: Thirty-six family members and spouses from a large kindred with Blau syndrome. SELECTION PROCEDURES: Volunteer and convenience sample. INTERVENTIONS: None. MEASUREMENTS AND RESULTS: Ten affected and many unaffected subjects were personally examined. Medical records and previous biopsy reports and specimens, when available, were reviewed. Two affected subjects had skin biopsies performed and three affected adult subjects were tested with Kveim skin-test reagent. Serologic and genomic class I and class II HLA typing was performed on 27 affected and unaffected subjects. All 13 living affected subjects and the one obligate carrier had the following assays performed; antinuclear antibody titer, rheumatoid factor, serum angiotensin converting enzyme level, quantitative immunoglobulins of the IgG, IgM, and IgA classes, and clinical chemistry profiles. Several had complete blood cell counts and erythrocyte sedimentation rates performed. Four affected subjects, one possibly affected subject, and one obligate carrier were newly identified. Flexion contractures of the fingers and toes (camptodactyly) were found, for the first time, to be a phenotype characteristic. Earlier onset and worsening of symptoms in succeeding generations (anticipation) were observed. Sixteen HLA haplotypes were identified. No conclusive evidence for linkage between these haplotypes and phenotype expression could be demonstrated. All 13 affected subjects, however, carried the DR2 (DR beta 1*1501) and/or DR4 (DR beta 1*0401) allele. There was no evidence of hypercalcemia, hypergammaglobulinemia M, rheumatoid factor production, or abnormal blood cell counts. Two affected subjects had low-titer antinuclear antibody screening tests, five had mild to moderately elevated IgG and/or IgA levels, two had raised serum angiotensin converting enzyme levels, and three had mild elevation of the erythrocyte sedimentation rate. All three subjects tested with Kveim skin-test reagent showed no reactivity by visual inspection. Both subjects who had had skin biopsies performed had evidence of granulomatous inflammation. CONCLUSIONS: This family's illness is distinct from both classic and early-onset sarcoidosis. There is minimal evidence for autoimmunity and systemic inflammation. Camptodactyly should be added to the list of syndrome-defining characteristics. Although HLA haplotypes do not appear to segregate with affected subjects, HLA-DR2 and HLA-DR4 subtypes may play a permissive role in phenotype expression. This family represents a unique opportunity to define the molecular mechanisms involved in the initiation of arthritis and uveitis in humans. Genetic linkage studies to determine the chromosomal location of the Blau syndrome gene are in progress.
