Background: The association between remote cerebellar hematoma (RCH) and spinal surgery is poorly understood and rarely reported. We present seven cases of RCH after spinal surgery. Methods: Seven patients were diagnosed with RCH utilizing computed tomography and/or magnetic resonance, between 2012 and 2016. Their clinical presentations, imaging data, treatment modalities, and outcome were analyzed. There were five females and two males with an average age of 55.8 ± 8.4 years. The age of onset ranged from 43 to 67 years and the time to clinical presentation ranged from 3 h to 5 days. Patients presented with: diplopia/strabismus (one patient), dysphagia/urinary incontinence (one patient), respiratory arrest (one patient), meningismus (one patient), and dysarthria (two patients), along with other symptoms/signs. Results: Three patients were successfully managed without surgery, two required external ventricular drainage, and two were treated with posterior fossa decompression plus ventriculostomy. Four patients recovered completely, two showed mild residual deficits at discharge, while one expired 7 days postoperatively. Conclusion: RCH is an uncommon and underdiagnosed complication of spine surgery. It should be suspected when intracranial symptoms occur after spinal procedures.

Introduction Meningiomas are the most common primary intracranial tumors, accounting for up to 35% of the neoplasms in this category. Approximately 10–20% of these neoplasms are histologically atypical, and the lymphoplasmacyte-rich meningioma (LPM) corresponds to a very rare subtype of meningioma that is characterized histopathologically by massive infiltrates of inflammatory cells. The case described in the present study is the sixth case of an intraventricular LPM found in the literature and the first case considering the location in the third ventricle. Case Description A 21-year-old male without previous comorbidities sought medical attention due to visual impairment (complaining of intermittent visual blur) for 2 months. A magnetic resonance imaging of the brain confirmed the presence of a well-delimited solid mass in the third ventricle of 3.0 × 2.3 cm with a cystic component that extended itself inferiorly and distorted the visual pathway anatomy. Neurosurgeons decided to access the lesion using an interhemispheric transcallosal approach with a transforaminal access, and the lesion was resected completely. The patient has an ambulatorial endocrinological follow-up and is neurologically stable 6 months after the procedure. No new visual deficits were noted. Conclusion Lymphoplasmacyte-rich meningioma is a very rare intracranial tumor, and the involvement of the third ventricle make this case unique

Background:Previous studies on the correlation between cervical sagittal balance with improvement in quality of life showed significant results only for parameters of the anterior translation of the cervical spine (such as C2-C7 SVA).Objective:We test whether a new parameter, cervicothoracic lordosis, can predict clinical success in this type of surgery.Methods:The focused group involved patients who underwent surgical treatment of cervical degenerative disk disease by the posterior approach, due to myelopathy, radiculopathy or a combination of both. Neurologic deficit was measured before and after surgery with the Nurick Scale, postoperative quality of life, physical and mental components of SF-36 and NDI. Cervicothoracic lordosis and various sagittal balance parameters were also measured. Cervicothoracic lordosis was defined as the angle between: a) the line between the centroid of C2 and the centroid of C7; b) the line between the centroid of C7 and the centroid of T6. Correlations between postoperative quality of life and sagittal parameters were calculated.Results:Twenty-nine patients between 27 and 78 years old were evaluated. Surgery types were simple decompression (laminectomy or laminoforaminotomy) (3 patients), laminoplasty (4 patients) and laminectomy with fusion in 22 patients. Significant correlations were found for C2-C7 SVA and cervicothoracic lordosis. C2-C7 SVA correlated negatively with MCS (r=-0.445, p=0.026) and PCS (r=-0.405, p=0.045). Cervicothoracic lordosis correlated positively with MCS (r=0.554, p= 0.004) and PCS (r=0.462, p=0.020) and negatively with NDI (r=-0.416, p=0.031).Conclusion:The parameter cervicothoracic lordosis correlates with improvement of quality life after surgery for cervical degenerative disk disease by the posterior approach.

Background Stroke is a clinical syndrome characterized by a sudden-onset neurological deficit of vascular cause. Stroke-like clinical symptoms that are later found to have nonvascular disorders have been termed stroke mimics (MIM), and their incidence ranges from 1.3 to 25% in patients not treated with thrombolytic therapy. Eventually, intravenous thrombolysis of MIM may occur. Case Description We describe a 74-year-old woman with abrupt global aphasia who received thrombolytic therapy after the presumed diagnosis of acute ischemic stroke. She gradually improved despite the finding of an asymptomatic left temporal hematoma on the computed tomography (CT) scan. Two months later, she presented with a new focal neurological deficit and was diagnosed with a glioblastoma in the topography of the previous bleeding. Conclusion This case highlights the rare occurrence of hemorrhage after thrombolysis in patients with MIM.

A paralisia de C5 é uma conhecida complicação de cirurgia de descompressão medular cervical devido à mielopatia espondilótica crônica, que pode ser definida como déficit motor do deltóide e/ou do bíceps braquial, déficit sensitivo no território de C5, ou aumento da dor no território de C5 comparado ao status pré-operatório. Apresentamos um relato de caso de um paciente com mielopatia espondilótica cervical que foi submetido à laminectomia dos níveis C4 a C6 e evoluiu com paralisia de C5, obtendo melhora muito significativa em aproximadamente um ano. A incidência de paralisia de C5 pós-operatória pode variar de 0 a 30%, conforme a literatura. A fisiopatologia da paralisia pós-operatória de C5 ainda não é bem compreendida. Os pacientes geralmente têm bom prognóstico. A recuperação é espontânea, o que justifica o emprego de tratamento conservador. Há estudos comparando diferentes técnicas empregadas para descompressão medular cervical quanto à recuperação neurológica e a ocorrência de paralisia pós-operatória de C5, bem como avaliando o valor preditivo de monitoração neurofisiológica.
