ABSTRACT
Objetivo: Presentar los resultados de tratamiento quirúrgico obtenidos en una serie de 14 casos de malformación cavernosa, situadas en diferentes localizaciones encefálicas, además de realizar una revisión bibliográfica sobre el tema. Material y métodos: En el periodo de los años 2014-2019, se diagnosticaron y protocolizaron 14 pacientes por medio de la consulta externa de neurocirugía del Hospital Juárez de México. Todos menos 2, fueron intervenidos quirúrgicamente. Resultados: En 12 de los 14 casos que recibieron tratamiento quirúrgico, se documentó mejoría neurológica posterior a la resección total en 10 pacientes, 1 paciente de cavernoma gigante temporal se hizo resección subtotal, en 1 paciente con lesión de localización protuberancial se le realizó únicamente drenaje de hematoma. El déficit preoperatorio tendió a mejorar progresivamente en las lesiones de mayor tamaño y en ningún caso se documentaron complicaciones, las crisis convulsivas se controlaron disminuyendo progresivamente la dosis de fármacos anticonvulsivantes en el periodo postquirúrgico de este grupo de pacientes. Y dos pacientes, uno con lesión mesencefálica y el otro con cavernomatosis solo se sometieron a observación. Conclusiones: La cirugía es el método de elección hoy en día para el tratamiento de las malformaciones cavernosas, siendo los mejores resultados a menor tamaño de la lesión y con localizaciones más superficiales. Los resultados quirúrgicos de nuestros pacientes son similares a lo reportado en la literatura mundial.
Objectives: To present the surgical outcomes obtained in a series of 14 cases of cavernous malformation, located in different brain locations, in addition to conducting a literature review on the subject. Method: Between the years, 2014 and 2019, 14 cases were diagnosed and protocolized in neurosurgery department of Hospital Juárez of México. All patients except two, were surgically treated. Results: In 12 of the 14 cases received surgical treatment, neurological improvement was documented after the total resection in ten patients, one patient with giant temporal cavernoma performed a subtotal resection, other case with a lesion in the pontine location a hematoma drainage was performed. All surgical patients the preoperative clinical deficit tended to improve progressively in larger lesions and no complications were documented. Seizures were controlled by gradually decreasing the dose of anticonvulsant drugs in the post-surgical period of this group of patients. And two patients, one with mesencephalic lesion and another with cavernomatosis, were only observe. Conclusion: Surgery is the method of choice today for the treatment of cavernous malformations, with the best outcome being the smallest size of the lesion and with more superficial locations. The surgical outcomes in our patients are similar to those reported in the world literature

RESUMEN El síndrome de Millard-Gubler es considerado un síndrome protuberancial debido a una lesión pontina inferior y caracterizado, desde el punto de vista clínico, por parálisis facial y del VI par, ipsilateral a la lesión y parálisis braquiocrural contralateral; frecuentemente es de causa vascular, menos frecuente de causa traumática o por efecto de masa secundario a un tumor. Se realiza reporte de un caso de un paciente de 45 años de edad que acude al servicio hospitalario de la Fundación Centro Colombiano y Enfermedades Neurológicas FIRE con cuadro clínico caracterizado en pérdida de la fuerza muscular en hemicuerpo izquierdo, y déficit motor de la hemicara derecha, disartria y deterioro del estado de consciencia. La TAC de cráneo simple al ingreso evidenció sangrado extenso del tallo cerebral. De acuerdo con los hallazgos clínicos se concluye que el paciente presentó un síndrome de Millard-Gubler.
SUMMARY The Millard Gubler syndrome is considered a protuberant syndrome due to a lower pontine lesion and characterized, from the clinical point of view, by facial paralysis and VI pares, ipsilateral to the lesion and contralateral brachiocrural palsy; frequently it is of vascular cause, less frequent of traumatic cause or by effect of mass secondary to a tumor. A case report is presented of a 45-year-old patient who attends the hospital service of the Fundación Centro Colombiano y Neurológicas FIRE with a clinical picture characterized by loss of muscle strength in the left side of the body, and motor deficit of the right side of the face, dysarthria and deterioration of the state of consciousness. The simple skull CT on admission showed extensive brainstem bleeding. According to the clinical findings, it is concluded that the patient presented a Millard Gubler syndrome.

Introducción: Las lesiones del tronco cerebral son uno de los mayores desafíos neuroquirúrgicos. Los angiomas cavernosos de esta localización son lesiones de comportamiento agresivo, con alta morbi-mortalidad asociada, donde el neurocirujano tiene la posibilidad de curar al paciente pero con un nivel de riesgo que hacen que la oportunidad de la cirugía se mantenga en debate. Material y Método: Análisis retrospectivo de 8 casos de cavernomas de tronco operados entre los años 2009-2013 con sus características clínicas, quirúrgicas y de seguimiento. Se realiza además una revisión reflexiva sobre la evolución del manejo de estas lesiones y del estado del arte a nivel en el concierto internacional. Resultados: Los 8 casos presentaron evoluciones inmediatas y mediatas favorables tras la cirugía. No hubo mortalidad ni empeoramiento del status neurológico en relación al estado preoperatorio en ninguno de los 8 casos. Tres de los pacientes de la serie fueron operados tras caer en una condición clínica crítica y son los que registran los mayores déficits durante el seguimiento. El análisis de la evolución del manejo de este tipo de lesiones a nivel mundial revela una tendencia hacia el manejo quirúrgico precoz en lesiones sintomáticas. Conclusiones: Los resultados de esta serie así como la evolución del estado del arte permiten concluir que en pacientes sintomáticos una cirugía precoz ofrece en general mejores expectativas que intervenciones tardías para lesiones relativamente superficiales.
Introduction: Brainstem lesions are a major neurosurgical challenge. Cavernous angiomas of this location are lesions of aggressive behavior, with high morbidity and mortality associated, where the neurosurgeon has the possibility to cure the patient but with a level of risk that makes that the surgery timing remains under debate. Material and Methods: A retrospective analysis of 8 brainstem cavernomas cases operated in the period 2009-2013 is presented whit its clinical, surgical and follow-up characteristics. A thoughtful review of the evolution of the management of these lesions and the state of art in the international level is also carried out. Results: All 8 patients presented immediate and mediate favorable changes after surgery. There was no mortality or worsening of the neurological condition in relation to the preoperative status in any of the 8 cases. 3 patients in this series underwent surgery after falling in a critical condition and are those who have the highest deficit in the follow-up. The analysis of the evolution of the worldwide management of these injuries reveals a trend towards early surgical management in symptomatic lesions. Conclusions: The results of this series as well as the evolution of the state of the art let us conclude that in symptomatic patients an early surgery offers overall better expectations than later interventions in relatively superficial lesions.

Objectives: To determine the clinical presentation and treatment outcome of pediatric intracranial cavernous malformation (CM) in a single-centered institution. Methods: Clinical data review of 30 patients under 18 years-old who had undergone surgery for cavernous malformation from January 1993 to December 2011. Results: The Study Group included 18 males and 12 females (mean age: 8.7 years-old). Symptoms at presentation were seizures (16/30, 53.3%), headache (15/30, 50.0%), and focal neurological deficits (11/30, 36.6%). Multiple cavernous malformations were found in 5/30 (16.6%). According to location, patients were classified in groups: (G1) brain-steam in 5/30 (16.6%), (G2) cerebellum in 2/30 (6.6%), (G3) supratentorial associated with seizures in 16/30 (53.3%), and (G4) supratentorial without seizures in 7/30 (23.3%). Surgical resection was performed in 26 out of 30 (86.6%) patients. The mean follow-up period was 4.1 years. Of 15 children followed-up with preoperative seizures, all were rendered seizure-free after surgery. Conclusions: For symptomatic solitary cavernous malformation, the treatment of choice is complete microsurgical excision preceded by careful anatomical and functional evaluation. For multiple cavernous malformation or asymptomatic patients, the treatment modalities must be cautiously considered. .
Objetivos: Determinar a apresentação clínica e o acompanhamento do tratamento em crianças com angioma cavernoso intracraniano numa única instituição. Métodos: Revisão de dados clínicos de 30 pacientes menores de 18 anos com que passaram por uma cirurgia de angioma cavernoso intracraniano entre janeiro de 1993 a dezembro de 2011. Resultados: O grupo de estudo incluiu 18 sujeitos masculinos e 12 femininos (idade média: 8,7 anos). Os sintomas iniciais eram convulsões (16/30, 53,3%), cefaleia (15/30, 50,0%) e déficits neurológicos focais (11/30, 36,6%). Havia angiomas cavernosos intracranianos múltiplos em 5 de 30 (16.6%). A classificação foi feita em grupos de acordo com a localização: (G1) tronco cerebral em 5/30 (16,6%); (G2) cerebelo em 2/30 (6,6%); (G3) supratentoriais associados a convulsões em 16/30 (53,3%) e (G4) supratentoriais sem convulsões em 7/30 (23,3%). Ressecção cirúrgica foi realizada em 26 de 30 (86,6%) pacientes, com seguimento médio de 4,1 anos. De 15 crianças com convulsões pré-operatórias, todas ficaram livres das crises após a cirurgia. Conclusões: Para angioma cavernoso intracraniano solitário e sintomático, o tratamento de escolha é excisão microcirúrgica total precedida de avaliação funcional e anatômica meticulosa. Para angiomas cavernosos intracranianos múltiplos ou pacientes assintomáticos, as modalidades terapêuticas devem ser consideradas cautelosamente. .

Os autores apresentam um caso em que um angioma cavernoso, envolvendo o nervo óptico, comprometeu progressivamente a visão direita de um paciente do sexo masculino, de 29 anos de idade. O paciente foi operado e o anatomopatológico comprovou o diagnóstico. É feita a revisão da literatura, em que 18 casos foram previamente relatados, existindo o risco de hemorragia, acarretando a apoplexia quiasmática. A importância da ressonância magnética para o diagnóstico é confirmada. O diagnóstico precoce e a total remoção da lesão são o tratamento de escolha para essa lesão.
A case of a cavernous angioma of the optic nerve is presented and 18 previous literature reports were reviewed. The patient presented with gradually progressive right-sided visual disturbance. The surgicaland histological findings demonstrated a cavernous angioma which was totally removed, although, the visual deficit persisted. Review of previously reported cases revealed that cavernous malformations in the optic nerve or chiasma present haemorrhage more frequently than those in the brain. Early diagnosis with total excision is the treatment of choice for cavernous angioma of the optic chiasma.
