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.

Background: Lumbar plexus schwannomas are a rare occurrence in neurosurgery, with few reported cases and no standard surgical approach. This study describes a successful surgical resection with no complications using the Wiltse approach. Methods: Patient presented with an intra-psoas tumor suggesting schwannoma. We described the surgical technique involved step by step. Results: The patient recovered from the surgery with no complications. The anatomopathological examination confirmed the schwannoma diagnosis. The post operatory magnetic resonance imaging showed complete resection. Conclusion: This study shows that the use of Wiltse approach, mainly used for classical herniated disc extraforaminal, can be used successfully on Lumbar plexus schwannomas.

Background: Spinal cord compression is a common complication of spine metastasis and multiple myeloma. About 30% of patients with cancer develop symptomatic spinal metastases during their illness. Prompt diagnosis and surgical treatment of these lesions, although palliative, are likely to reduce the morbidity and improve quality of life by improving ambulatory function. Study Design: Retrospective review of medical records. Objective: To evaluate postoperative functional recovery and the epidemiological profile of neoplastic spinal cord compression in two neurosurgical centers in southern Brazil. Methods: We retrospectively analyzed the data of all patients who underwent palliative surgery for symptomatic neoplastic spine lesion from metastatic cancer, in two neurosurgical centers, between January 2003 and July 2021. The variables age, sex, neurological status, histological type, affected segment, complications and length of hospitalization were analyzed. Results: A total of 82 patients were included. The lesions occurred in the thoracic spine in 60 cases. At admission, 95% of the patients had neurological deficits, most of which were Frankel C (37%). At histopathological analysis, breast cancer was the most common primary site. After surgery, the neurological status of 46 patients (56%) was reclassified according to the Frankel scale. Of these, 22 (47%) regained ambulatory capacity. Conclusion: Surgical treatment of metastatic spinal cord compression improved neurological status and ambulatory ability in our sample. Level of evidence II; Retrospective study.

Calcified chronic subdural hematomas (CCSDHs) are rare entities, whose yearly incidence ranges from 1.72 to 20.6 per every 100 thousand persons. Several different approaches to their management are reported in the literature, ranging from conservative treatment to craniotomy with full removal of the neomembranes. Currently, there are no guidelines or consensus that establish the best technique. We herein report a case of symptomatic CCSDH initially drained through a burr-hole craniotomy, with no resolution of the symptoms. Later, our patient underwent a craniotomy and partial membranectomy, which resulted in full symptomatic recovery. Hematomas subdurais crônicos calcificados (HSDCCs) são entidades raras, cuja incidência anual varia de 1,72 a 20,6 casos a cada 100 mil pessoas. Várias abordagens diferentes para seu manejo são relatadas na literatura, desde o tratamento conservador até a craniotomia com remoção total das neomembranas. Atualmente não há diretrizes ou consensos que estabeleçam a melhor técnica. Nós relatamos um caso de HSDCC inicialmente drenado por meio de uma craniotomia por trepanação, sem resolução dos sintomas. Posteriormente, nosso paciente foi submetido a uma craniotomia e membranectomia parcial, que resultou em plena recuperação dos sintomas. ^* Study conducted at Hospital São José, Santa Casa de Misericórdia de Porto Alegre, Porto Alegre, Rio grande do Sul, Brazil.
