RESUMO
Spinal metastasis of Glioblastoma is a rare occurrence, especially in pediatric patients, and extremely rare to become symptomatic. The pathology is poorly understood and remains with unclear dissemination mechanisms. The treatment approaches are varied and multimodal therapy (surgery, chemotherapy, and radiotherapy) can be employed to manage this type of metastasis. We report a case of a 17-year-old female who underwent a gross-total resection of a right frontal glioblastoma and had adjuvant therapy with chemo- and radiotherapy. In the sixth month of follow-up, the patient presented a paraparesis, and a distant recurrence at T7-T8 was detected. The patient was treated with gross-total resection of the tumor through a laminectomy. The histopathological results were consistent with an isocitrate dehydrogenase (IDH) wildtype GBM metastasis. The patient was treated with multimodal therapy, including surgery, radiotherapy, and chemotherapy. A complementary comprehensive review of current available literature on this topic is also presented.
RESUMO
BACKGROUND AND OBJECTIVE: Awake craniotomy (AC) is a valuable technique for surgical interventions in eloquent areas, but its adoption in low- and middle-income countries faces challenges like limited infrastructure, trained personnel shortage, and inadequate funding. This scoping review explores AC techniques in Latin American countries, focusing on patient characteristics, tumor location, symptomatology, and outcomes. METHODS: A scoping review followed PRISMA guidelines, searching five databases in English, Spanish, and Portuguese. We included 28 studies with 258 patients (mean age: 43, range: 11-92). Patterns in AC use in Latin America were analyzed. RESULTS: Most studies were from Brazil and Mexico (53.6%) and public institutions (70%). Low-grade gliomas were the most common lesions (55%), most of them located in the left hemisphere (52.3%) and frontal lobe (52.3%). Gross-total resection was achieved in 34.3% of cases. 62.9% used an Asleep-Awake-Asleep protocol, and 14.8% used Awake-Awake-Awake. The main complication was seizures (14.6%). Mean post-surgery discharge time was 68 h. Challenges included limited training, infrastructure, and instrumentation availability. Strategies discussed involve training in specialized centers, seeking sponsorships, applying for awards, and multidisciplinary collaborations with neuropsychology. CONCLUSION: Improved accessibility to resources, infrastructure, and adequate instrumentation is crucial for wider AC availability in Latin America. Despite disparities, AC implementation with proper training and teamwork yields favorable outcomes in resource-limited centers. Efforts should focus on addressing challenges and promoting equitable access to this valuable surgical technique in the region.

Las lesiones difusas de médula son raras y un reto diagnóstico. Los gliomas de bajo grado son los de mayor prevalencia y los astrocitomas primarios, el subtipo más frecuente. Presentamos el caso de un varón de 36 años, con tiempo de enfermedad de 13 años de dolor cervical insidioso, progresa con hemiparesia derecha y, posteriormente, paraparesia severa con pérdida de control de esfínteres. Mediante una RMN total de columna se evidenciaron lesiones neoproliferativas difusas abarcando todos los segmentos medulares. Se realizó una biopsia a cielo abierto en segmento T1-T2, la patología diagnosticó glioma de bajo grado. El tratamiento es controversial y se descartó la cirugía por la alta morbilidad. Se optó por radioterapia y quimioterapia por su rol importante en el control de la enfermedad.
Diffuse spinal cord injuries are rare and pose a diagnostic challenge. Low-grade gliomas are the most prevalent type, with primary astrocytomas being the most frequent subtype. We present the case of a 36-year-old man with a 13-year history of squeezing neck pain, which progressed with right hemiparesis and later with severe paraparesis and loss of sphincter control. A whole spine MRI scan showed diffuse neoproliferative lesions that spread throughout all the spinal cord segments. An open biopsy of the lesion in the T1-T2 segment was performed. The pathology report stated low-grade glioma. Treatment is controversial, so surgery was ruled out due to high morbidity. Radiotherapy and chemotherapy were chosen because they play an important role in controlling the disease.
