Quistes sinoviales lumbares: presentación de una serie de 10 casos y revisión de la literatura / Lumbar synovial cysts: presentation of a series of 10 cases and literature review

Introducción. Los quistes sinoviales lumbares son una causa infrecuente de dolor lumbar y radicular, aunque cada vez se describen con más frecuencia en la literatura. Objetivo. Analizar el tratamiento y resultados quirúrgicos de los quistes sinoviales lumbares intervenidos en nuestro centro en un período de 5 años. Material y métodos. Se realizó un estudio retrospectivo de pacientes tratados quirúrgicamente en nuestro servicio entre agosto de 2009 y septiembre de 2014, empleando la escala visual analógica para seguimiento clínico durante el año posterior a la cirugía. Resultados. Tras el tratamiento quirúrgico (exéresis del quiste con o sin artrodesis instrumentada con tornillos transpediculares), de 10 pacientes (5 mujeres y 5 varones) de edades comprendidas entre los 50 y 80 años (edad media 70,2 años), la evolución clínica fue satisfactoria en el 80% de ellos con resolución de su sintomatología. Conclusiones. Los quistes sinoviales lumbares deben ser considerados en el diagnóstico diferencial de pacientes con dolor lumbar y radicular. La mayoría de estos pacientes están en la 6.a década de la vida y presentan generalmente una espondilopatía degenerativa lumbar. En la actualidad, se recomienda la exéresis de los quistes sinoviales con artrodesis instrumentadas con tornillos transpediculares, ya que se considera que el aumento de movilidad podría ser una de las causas de su aparición; aunque todavía se necesitan más estudios al respecto, de ahí el interés de este trabajo (AU)

Introduction. Although they are freqqently described in the literature, lumbar synovial cysts are a relative uncommon cause of low back and radicular leg pain. Objective. To evaluate the treatment and surgical outcomes of the lumbar synovial cysts operated on in our hospital during a 5 year period. Material and methods. A retrospective study was conducted on patients surgically treated in our department from August 2009 to September 2014, using a visual analogue scale for the clinical follow-up in the first year after surgery. Results. After the surgical treatment (surgical removal of the synovial cyst with or without instrumented arthrodesis with transpedicular screws) of 10 patients (5 female and 5 male) with a mean age of 70.2 years (range 50-80), the clinical outcome was satisfactory in 80% of the patients, with the resolving of their symptoms. Conclusions. Lumbar synovial cysts have to be considered in the differential diagnosis in patients with low back and radicular leg pain. The majority of the patients are in their sixties and have lumbar degenerative spondylopathy. Nowadays, surgical resection of the lumbar synovial cysts and spinal fusion are the recommended treatment, because it is thought that the increased movement of the spine is one to the causes of the cyst formation. More studies are still needed, hence the relevance of this article (AU)

Congenital obstruction of the foramen of Monro causing unilateral hydrocephalus. A propos of a case / Oclusión congénita del foramen de Monro como causa de hidrocefalia unilateral. A propósito de un caso.

Isolated hydrocephalus of the lateral ventricle may result from unilateral occlusion of the foramen of Monro. The most common causes are tumours of the lateral ventricles or in the area of the third ventricle. Non-tumoural stenosis of the foramen is rare and can be due to inflammatory, vascular or congenital conditions. A full-term infant was prenatally diagnosed with unilateral hydrocephalus. After birth, progressive unilateral ventricular dilatation was confirmed in successive ultrasounds so surgery was indicated. The patient underwent endoscopic fenestration of the foramen of Monro and septostomy with good postoperative clinical evolution and reduction of ventricular size. Intraoperative findings demonstrated membranous obstruction of the right foramen of Monro. A successful treatment can be accomplished through a neuroendoscopic approach avoiding the use of ventricular shunts.

Oclusión congénita del foramen de Monro como causa de hidrocefalia unilateral. A propósito de un caso / Congenital obstruction of the foramen of Monro causing unilateral hydrocephalus. A propos of a case

La hidrocefalia aislada del ventrículo lateral puede ser provocada por la oclusión unilateral del foramen de Monro. Las causas más frecuentes son los tumores de los ventrículos laterales o en el área del tercer ventrículo. La estenosis no tumoral es poco frecuente y puede deberse a patologías inflamatorias, vasculares o congénitas. Se presenta el caso de un recién nacido a término diagnosticado prenatalmente de hidrocefalia unilateral. Tras el parto se confirmó en las sucesivas ecografías la dilatación ventricular unilateral motivo por el cual se indicó el tratamiento quirúrgico. El paciente fue sometido a la fenestración del foramen de Monro y septostomía por vía endoscópica, con buena evolución clínica y reducción del tamaño ventricular. Los hallazgos intraoperatorios demostraron la obstrucción por una membrana del foramen de Monro derecho. Se puede conseguir un tratamiento adecuado mediante neuroendoscopia, evitando implantar derivaciones ventriculares (AU)
