Introduction: Neurocysticercosis is a disease with high neurological morbidity, where subarachnoid subtype is a severe form. Secondary vasculitis is rare, but it can cause a stroke. The diagnosis is made by serology with enzyme-linked immunotransfer blot (ELIB) and tomography or resonance images with 3D sequence. Treatment is mainly medical. Case of report: A 28-year-old male with headache, expression aphasia and dysarthria. The images show a left frontal stroke, as well as a non-viable left temporal cyst and another viable left sylvian lesion, with positive ELIB. He was treated with clinical improvement. At 8 months, imaging control was performed due to new stroke. We saw reduction in size of the lesions, but still positive ELIB, so medical treatment was restarted with slow improvement of symptoms. Conclusion: Subarachnoid neurocysticercosis is a complex pathology, which requires multid...

Introducción: El linfoma óseo espinal es una enfermedad rara, siendo el linfoma difuso de células B grandes el subtipo más frecuente. Por lo general es una manifestación tardía de una enfermedad sistémica. Su manejo es multidisciplinario, incluyendo la cirugía, la quimioterapia y la radioterapia. Caso Clínico: Mujer de 40 años, con antecedente de infección por el virus de inmunodeficiencia humana, tuberculosis miliar monorresistente a isoniacida, con tiempo de enfermedad de 7 meses con déficit motor y sensitivo progresivo además de alteración esfinteriana. La resonancia contrastada muestra un proceso expansivo vertebral y paravertebral izquierdo que invade canal raquídeo por la forámina T2/T3 izquierda, con compresión medular. Se realiza laminectomía T2 y T3 más resección total de tumor más fijación espinal. La paciente recupera el déficit motor de manera progresiv...

Introduction: Spinal bone lymphoma is a rare disease, with diffuse large B-cell lymphoma being the most common subtype. It is usually a late manifestation of a systemic disease. Its management is multidisciplinary, including surgery, chemotherapy and radiotherapy. Clinical case: A 40-year-old woman, with human immunodeficiency virus infection, miliary tuberculosis monoresistant isoniazid, with disease period of 7 month with progressive motor and sensory deficit in addition to sphincter dysfunction. The contrasted MRI shows a left vertebral and paravertebral tumor that invades spinal canal through left T2/T3 foramina with spinal cord compression. Laminectomy T2 and T3 plus total resection of tumor plus spinal fixation is performed. The patient progressively recovered the motor deficit and began chemotherapy with a good response. Conclusion: The spinal bone lymphoma is an infrequent etiolo...

Introducción: El complejo C0-C1-C2 es responsable de la transición de la carga axial, con función biomecánica única, siendo afectada por múltiples patologías, que por lo general la literatura no las considera como un solo ítem, sino que lo desarrolla según su etiología, pero en nuestro estudio se ha considerado en 5 grupos: traumática, congénita, inflamatoria reumática, neoplásica y degenerativa. Objetivo: Determinar las características epidemiológicas, clínicas y del tratamiento en la patología cervical alta. Materiales y métodos: Se incluyeron a todos los pacientes con diagnóstico clínico radiológico de alguna patología cervical alta que hayan sido sometidos a tratamiento quirúrgico entre 2016 y 2021 en el Hospital Almenara. Se usó el test “t” de student y de chi cuadrado. Se dividió a los pacientes en alguno de los 5 grupos antes mencionados. Resultados: ...

Introduction: The C0-C1-C2 complex is responsible of axial load transition, and its biomechanical function is unique, it is affected by multiple pathological conditions; and generally speaking, the literature does not consider these conditions as a single item, it describes them according to etiology. For our study we considered five groups: trauma-related, congenital, rheumatic-inflammatory, neoplastic, and degenerative. Objective: To determine epidemiological, clinical, and therapy-related characteristics in upper cervical pathological conditions. Materials and methods: All patients with a clinical-radiological diagnosis of any upper cervical pathological condition that had undergone surgery between 2016 and 2021 in Guillermo Almenara Hospital were included. Student’s t test and chi square methods were used. Patients were divided into five groups: congenital, trauma-related, rheumati...

Los gliomas múltiples (multifocales y multicéntricos) son poco frecuentes en los gliomas de bajo grado. La etiología de los gliomas multicéntricos es poco conocida y su manejo es controversial. Se presenta el caso de una paciente de 27 años, con dos lesiones compatibles imagenológicamente con glioma de bajo grado, confirmado por estudio anatomopatológico; recibe manejo con quimioterapia y radioterapia manteniéndose la enfermedad estable a un año de seguimiento; no pudo ser sometida a cirugía debido a que las lesiones se encontraban en áreas elocuentes. Para este tipo de pacientes el tratamiento de elección es la cirugía, siempre que sea factible, según elocuencia y compromiso vascular, seguido de esquemas de quimioterapia y radioterapia, según el esquema que se da en gliomas únicos. Por ello, los gliomas multicéntricos de bajo grado son una patología rara que debe ser m...

Los hemangiomas del seno cavernoso son considerados como malformaciones vasculares o tumores vasculares, se desarrollan extraaxiales, pero son histológicamente distintos a la malformación cavernomatosa cerebral. Su clínica puede ser cefalea, alteraciones visuales o paresia de pares craneales. Los métodos diagnósticos son la tomografía, pero principalmente la resonancia contrastada. El tratamiento puede ser mediante microcirugía o radioterapia. Se presenta el caso de un varón de 30 años, sin antecedentes, con 3 años de evolución de cefalea, y 7 meses de diplopía por paresia del VI par craneal. La resonancia contrastada evidencia un proceso expansivo en el seno cavernoso derecho, bordes regulares, hipointensa en T1, hipercaptador de contraste, hiperintensa en T2 y FLAIR, que no restringe en difusión. Se le realizó una craneotomía más resección total de la tumoración con a...

Multiple gliomas (multifocal and multicentric) are rare in low-grade gliomas. In multicentric gliomas, their etiology is poorly understood, and their management is controversial. A 27-year-old female patient, with two lesions compatible with low-grade glioma, confirmed by pathological study, for which; she received chemotherapy and radiotherapy, maintaining stable disease after one year of follow-up; she could not undergo surgery because the lesions were located in eloquent areas. For this type of patient, the standard of care is surgery whenever feasible based on eloquence and vascular involvement, followed by chemotherapy and radiotherapy like treatment given in single gliomas. Low-grade multicentric gliomas are a rare pathology that must be managed by a multidisciplinary team where surgery is the standard of care whenever feasible, followed by chemotherapy and radiotherapy.

Objective: To determine clinical and angiographical outcomes in patients with multiple intracranial aneurysms who underwent endovascular therapy in a single session. Materials and Methods: Patients older than 18 years with multiple (≥2) ruptured or non-ruptured aneurysms were included, and all of them underwent endovascular therapy in a single session between 2019 and 2021. Clinical and angiographic data was collected. Immediate occlusion and follow-up data were collected. Rankin modified scale was used for assessing clinical outcomes. Results: Twenty-five patients were treated, and fourteen had subarachnoid hemorrhage. Seventy-eight aneurysms were diagnosed, and 59 of them were treated. The most frequent location was at the ophthalmic segment. Maximum average height was 5.2- mm, which showed significant statistical difference with a ruptured condition (p≤0.02). The main modality for...

Cavernous sinus hemangioma is considered as a vascular malformation or as a vascular tumor. It is usually extra-axially located, but it is histologically different from cavernomatous cerebral malformations. Clinical features may include headache, visual alterations or cranial nerve palsy. Diagnostic methods include CT scans, but the best is contrast-enhanced magnetic resonance imaging (MRI). Therapy may be microsurgery or radiotherapy. We present the case of a 30-year-old male, with no relevant past history, who had suffered with headache for three years, and diplopia for the last seven months, due to paresis affecting the sixth cranial nerve. Contrast-enhanced MRI showed an expansive lesion in the right cavernous sinus, with regular borders, T1 hypointense, with significant contrast uptake, T2 and FLAIR hyperintense, with no diffusion restriction. A craniotomy plus total resection of th...
