Síndrome de Bruns Garland. Informe de un caso y diagnóstico diferencial con el síndrome de cauda equina / Bruns Garland syndrome. Report of a case and differential diagnosis with cauda equina syndrome

Resumen: Antecedentes: El síndrome de Bruns Garland (amiotrofia diabética) es una condición con pocos casos reportados en la literatura. La diferenciación clínica de una amiotrofia diabética o un síndrome de cauda equina puede ser difícil. El problema de un mal diagnóstico ha sido discutido como una razón para un mal resultado después de una cirugía de la columna lumbar. Se presenta un caso de amiotrofia diabética que imita un síndrome de cauda equina. Descripción del caso: Masculino de 59 años de edad con diabetes, comienza repentinamente con debilidad en las extremidades inferiores y pérdida del control de los esfínteres. Este paciente fue atendido en la sala de urgencias, las radiografías anteroposterior y lateral de la columna lumbosacra evidenciaron espondilolistesis L5-S1 nivel II de Meyerding. Sin embargo, la IRM no mostró ninguna compresión del canal vertebral, compresión de la raíz nerviosa, ni extrusión del disco. El estudio de electrodiagnóstico reveló amiotrofia diabética (síndrome de Bruns Garland). El paciente rápidamente mejoró con el tratamiento basado en antineuríticos, control diabético, terapia física y rehabilitación. Cuatro meses después del diagnóstico, el paciente recuperó su fuerza muscular, no mostró alteraciones en la marcha, ni pérdida del equilibrio, su sensibilidad se conserva y no manifiesta dolor. Discusión: Deberán utilizarse estudios de electrodiagnóstico y radiológicos en todo paciente diabético que presente dolor en la pierna y/o debilidad para diferenciar una neuropatía diabética de un síndrome de cauda equina. El tratamiento en ambas enfermedades puede ser necesario para aliviar el dolor del paciente.

Abstract: Background: The Bruns Garland syndrome (diabetic amyotrophy) it is a very rare condition, with few cases reported in the literature. Clinical differentiation of diabetic amyotrophy or cauda equine syndrome may be difficult. The issue of misdiagnosis has been discussed as a reason for poor outcome after lumbar spine surgery. We report a case of diabetic amyotrophy that mimics a cauda equina syndrome. Case description: A 59 years old man diabetic patient that suddenly begins with weakness of lower extremities and loss of sphincters control. The patient was seen in the emergency room, the anteroposterior and lateral radiographs of the lumbosacral spine evidenced spondylolisthesis L5-S1 level II of Meyerding. However, the MRI show no vertebral canal compression, nerve root compression or disc extrusion. Electrodiagnostic study revealed diabetic amyotrophy (Bruns Garland syndrome). The patient rapidly improves with treatment based in antineuritics, diabetes control, physical therapy and rehabilitation. Four months after the diagnosis he recover his muscle strength, has no alterations in the march, no loss of balance, his sensitive is preserved and has no pain. Conclusion: Electrodiagnostic and radiologic studies should be used in every diabetic patient presenting with leg pain and/or weakness to differentiate diabetic neuropathy from cauda equina syndrome. Treatment of both diseases may be needed for relief of the patient's pain.

Neurocysticercosis, unusual manifestations / Neurocisticercosis, manifestaciones inusuales

Abstract Neurocysticercosis is the most common parasitic infection in the central nervous system. This disease is presented when a person ingests Taenia solium eggs excreted in feces from another individual infected with taeniasis. In 50% of the cases, neurocysticercosis takes place in the brain parenchyma, and its appearance is less frequent in the posterior fossa and the spinal cord. The case of a patient with an atypical location of the parasite at the medulla oblongata, between parenchymal and spinal areas, is presented. The initial symptoms were common but its subsequent manifestations were similar to those of Bruns syndrome. Furthermore, the epidemiological profile of neurocysticercosis in Colombia, its control measures and prevention strategies were reviewed in this study.

Resumen La neurocisticercosis es la infección parasitaria más frecuente en el sistema nervioso central; esta enfermedad se desarrolla cuando los huevos de Taenia solium excretados en heces de un individuo con teniasis son ingeridos por otra persona. La presentación de la neurocisticercosis tiene lugar en el parénquima cerebral en 50% de los casos, mientras que en la fosa posterior y en la médula espinal es menos frecuente. Se presenta el caso de un paciente que tuvo una ubicación exótica del parásito a nivel del bulbo raquídeo concomitando con la forma parenquimatosa y medular; las manifestaciones clínicas iniciales fueron las comunes, pero sus síntomas posteriores se caracterizaron por el síndrome de Bruns. Además, durante la investigación se revisó el perfil epidemiológico de la neurocisticercosis en Colombia y las medidas de control y de prevención.

Emergency Neuroendoscopic Management of Third Ventricular Neurocysticercosis Cyst Presented with Bruns Syndrome : Report of Two Cases and Review of Literature

Neurocysticercosis is the commonest parasitic disease of the human central nervous system. The incidence of intra ventricular form of neurocysticercosis (NCC) is less common accounting 10-20% that of total central nerve system cysticercosis. Intra ventricular NCC is complicated due, to its high incidence of acute hydrocephalus caused by ball valve mechanism. The only reliable tool for diagnosis of NCC is by neuroimaging with CT or MRI. MRI preferred over CT because of its high specificity and sensitivity. In emergency situations like acute hydrocephalus one can proceed with emergency endoscopic surgery. Through the endoscopic view, intra ventricular NCC (IVNCC) has distinguished morphological features like the full moon sign. This feature not only helps in identification of IVNCC, but also guides in further endoscopic treatment strategy. Authors report two cases of 3rd ventricular NCC with acute hydrocephalus managed with emergency endoscopy. Authors have discussed the clinical features, intra operative endoscopic findings and role of endoscopy in emergency surgery for NCC with acute hydrocephalus.

Bruns' syndrome and racemose neurocysticercosis: a case report / Síndrome de Bruns e neurocisticercose racemosa: relato de caso

Cysticercosis is an infection caused by the larval stage of the tapeworm Taenia solium. The parasite may infect the central nervous system, causing neurocysticercosis (NCC). The clinical manifestations depend on load, type, size, location, stage of development of the cysticerci, and the host's immune response against the parasite. The racemose variety occurs in the ventricles or basal cisterns and is a malignant form. Mobile ventricular mass can produce episodic hydrocephalus on changing head posture with attacks of headache, vomiting, and vertigo, triggered by abrupt movement of the head, a phenomenon called Bruns' syndrome (BS). We report a patient with racemose NCC and BS.

A infecção por cisticercose é causada pelo estágio larval da Taenia solium. O parasita pode infectar o sistema nervoso central, causando neurocisticercose (NCC). As manifestações clínicas dependem da quantidade, tipo, tamanho, local, estágio de desenvolvimento do cisticerco e resposta imune do hospedeiro contra o parasita. A variedade racemosa ocorre nas cisternas ventriculares ou basais e é considerada uma forma maligna. O cisticerco móvel no ventrículo pode produzir hidrocefalia episódica com ataques de cefaléia, vômitos e vertigem, provocados pelo movimento abrupto da cabeça, fenômeno chamado de síndrome de Bruns (SB). Relataremos o caso de uma paciente com NCC racemosa com SB.

Bruns-Garland syndrome: a report of two cases / 重庆医科大学学报

Objective:To investigate the clinic characters and diagnosis of Diabetic amytrophy.Methods:Two cases were systematically studied by the authors.Results:All the two cases were senile patient with type 2 diabetes mellitus.The clinical manifestations include chronic and subacute proximal amytrophy,weakness and pain of lower limbs,There were no specific auxiliary examination.Conclusion:Diabetic amyotrophy is often misdiagnosed.And careful history inquiry and physical examination can contribute to identification at an early stage,excluding other differential diagnosis.
