Abstract Objectives This study was to demonstrate surgical technique for an anterolateral foramen magnum meningioma. Design Present study is presented through an operative video. Setting This study is conducted at the Department of Neurosurgery, Tîrgu Mureș, Romania. Participants A 62-year-old female is the participant who was diagnosed with a foramen magnum meningioma. Main Outcome Measures Complete surgical resection of the tumor with no postoperative deficits or complications. Results A 62 years-old female was admitted for left hemilingual atrophia, dysphonia, right hemiparesis grade 2 of 5, right hemihypesthesia, and cervical pain. The magnetic resonance imaging (MRI) showed a right foramen magnum meningioma, sized approximately 2 cm in all planes (Fig. 1). This was classified with the Bernard system as an intradural foramen magnum meningioma with anterolateral insertion to the dura mater and below the vertebral artery. A suboccipital, retrocondylar, and c1 right hemilaminectomy approach was performed. Using microsurgical tumoral decompression techniques, ultrasonic aspiration, and following the natural cleavage planes, complete tumor removal was achieved (Fig. 2). The patient presented an uneventful postoperative course with no postoperative new neurological deficits and was discharged at home 7 days following surgery. Control MRI at 6 months (Fig. 1) and 2 years showed no tumor residue or recurrence. Neurologic status at 6 months was excellent, showing complete remission of symptoms. Conclusion Retrocondylar suboccipital approach is a safe and feasible option for anterolateral foramen magnum meningiomas provided that natural corridors and dynamic retraction are used.The link to the video can be found at: https://youtu.be/jpxMcjCpN6E.

Abstract The long-term results obtained in a series of 174 patients operated on for spinal meningiomas are critically analyzed. This series was similar to those of other authors with regard to age, sex, location of the tumors, and clinical presentation. Before surgery, about 70% of the patients were included in Groups I and II (mild neurological impairment), and about 30% of the patients were classified in Groups III and IV (significant to severe neurological impairment, up to paraplegia). Complete tumor removal was achieved in 96.5% of the patients, and surgical mortality was about 1%. Microsurgical technique, which was adopted in the last 29 cases, proved to be very effective in reducing undue damage to the spinal cord and in minimizing the postoperative neurological deficits. Of the 174 patients who underwent surgery, 156 underwent late follow-up study for an average of 15 years (2 patients died in the immediate postoperative period, and 16 patients were lost to follow-up). Twenty-nine patients died of causes unrelated to the spinal meningioma; of the remaining 126 patients, 92% were categorized in Groups I and II, and only 8% in Groups III and IV. The rate of recurrence was 6% (9 patients) among the 150 patients who had complete tumor removal, and the rate of regrowth was 17% (1 patient with anaplastic meningioma) among the 6 patients treated by subtotal removal. The early diagnosis of the disease and the use of microsurgical technique appeared as the most relevant factors for further improvement of the surgical results.

Background: Intracranial cysts in the prepontine region are rare and can lead to various complications if not managed appropriately. Symptomatic prepontine cysts may require surgical intervention. However, spontaneous resolution of such cysts is rarely reported in literature. Case Description: We describe the case of a middle-aged lady who presented with headaches and imbalance, with no focal neurological deficits on examination. Magnetic resonance imaging (MRI) of the brain showed a prepontine cyst compressing the brainstem with craniocaudal extension through the foramen magnum. The patient was given symptomatic treatment and followed closely with repeat MRI scans. These scans showed regression and eventual disappearance of the lesion, with complete resolution of symptoms. Conclusion: In light of the few reported cases of spontaneous resolution of prepontine cysts, we highlight the possibility of these lesions to self-resolve.

Spinal Epidural

Spinal epidural abscess (SEA) is a rare disease which is often rapidly progressive. Delayed diagnosis of SEA may lead to serious complications and the clinical findings of SEA are generally nonspecific. Paraspinal abscess should be considered in the presence of local low back tenderness, redness, and pain with fever, particularly in children. In case of delayed diagnosis and treatment, SEA may spread to the epidural space and may cause neurological deficits. Magnetic resonance imaging (MRI) remains the method of choice in the diagnosis of SEA. Treatment of SEA often consists of both medical and surgical therapy including drainage with percutaneous entry, corpectomy, and instrumentation.

Abstract The cases of 16 patients with acoustic neurinomas confined to the intracanalicular area are presented. These represent 2.7% of the 600 patients with acoustic neurinomas consecutively operated upon at the Neurosurgical Clinic at Nordstadt Hospital during the last 8 years. The comparatively earlier onset of vestibular symptoms and signs was characteristic of this group and precipitated diagnosis. The diagnostic reliability of magnetic resonance imaging was at least equivalent to that of air computed tomographic cisternography. Complete tumor removal was accomplished via the suboccipital approach in all patients, with 100% preservation of facial nerve and facial function; the cochlear nerve was preserved anatomically in 100% of the patients and functionally in 57%. No recurrence has occurred during follow-up periods of up to 8 years in all 16 patients. A broad spectrum of the current literature is considered, and purely intracanalicular acoustic neurinomas are discussed with regard to clinical characteristics, diagnostic steps—including neuroradiological and neurophysiological approaches—and surgical treatment and results.

✓ Spinal ependymomas may rarely arise from heterotopic ependymal cell clusters and thus occur in an extraspinal location. Presentation of three cases and a review of the literature reveal that these tumors have characteristic radiographic and clinical features. They occur mainly in patients in the third decade of life, and present either in the soft tissue posterior to the sacrum or in the pelvis. In the case of posterior tumors, the patient exhibits a mass which is usually mistaken for a pilonidal cyst. Patients whose tumor is pelvic in location present with sphincter disturbances or dysfunction of the sacral nerve roots. Conventional and computerized tomographic studies will reveal erosion of the sacrum. Myelography will demonstrate an extradural mass indenting the thecal sac from below. The protein in the cerebrospinal fluid will be normal. A combined posterior and anterior approach with the goal of complete tumor removal is the procedure of choice. If this is not feasible, then radiation therapy should be employed. Because of the increased incidence of systemic metastases, the average postoperative survival is approximately 10 years.

Background Isolated body lateropulsion is a possible predominant manifestation of medulla oblongata infarction, and can occur without vestibular and cerebellar symptoms. However, it is relatively rare and challenging to diagnose. Case presentation A 67-year-old woman was admitted to the Harris International Peace Hospital complaining mainly of instability when standing and walking for the previous 8 hours. Based on the neural localization and multiple head magnetic resonance imaging (MRI) examinations, a diagnosis of cerebral infarction (vertebrobasilar system) was made. Consequently, the patient was managed using therapy aimed at preventing platelet aggregation, lowering plasma lipids, stabilizing plaques, protecting mitochondria, and improving circulation and brain function. The patient’s gait improved and she was discharged after 14 days because she was able to walk unaided. The patient was followed up for 6 months and had no noticeable undesirable side effects or signs of neurological deficits. Conclusion The possibility of lateral medulla oblongata infarction should be considered when patients present with isolated body lateropulsion, without other signs or symptoms of brainstem damage.

Spinal ependymomas (SEs) are common adult intramedullary tumors; however, determining the absolute boundary between the tumor and the tumor residual may be difficult. We assessed outcomes following the use of fluorescein sodium (FS) during surgical removal of SEs. We performed a retrospective analysis of 112 patients with SEs who were treated at Beijing Tsinghua Changgung Hospital between December 2014 and December 2016. Each patient received intravenous FS (3–4 mg/kg) to determine the SE boundaries during surgery. Tumor removal efficiencies and tumor residuals were assessed using magnetic resonance imaging (MRI) at 10 days and 3 months after surgical recovery; McCormick's spinal function classification was also performed at the 3-month follow-up. The complete tumor removal rate was 92% (103/112). Ninety-four patients underwent tumor removal under fluorescent light, which provided distinctive tumor fluorescence. Tumor removal under white light was performed in 18 patients; fluorescent images were invisible or indistinctive in these 18 patients. At the 3-month follow-up, sensory function (85.8% (91/106)) and movement (84.3% (86/102)) were improved in patients with pre-surgical dysfunction; urination and defecation functions were improved in 66.7% (16/24). The McCormick spinal cord functional classifications, at the 3-month follow-up, showed significant differences in the percentages of patients with disease classified to each grade (I–IV), compared with preoperative classifications (each, P < 0.05). There was no MRI evidence of tumor relapse or residuals at the 3-month follow-up. FS use during the surgical treatment of SE enables complete tumor removal and detection of tumor residuals.

Summary Chiari malformation (CM) is the most common and prevalent symptomatic congenital craniocervical malformation. Radiological diagnosis is established when the cerebellar tonsils are located 5 mm or more below the level of the foramen magnum on magnetic resonance imaging (MRI). Surgical treatment is indicated whenever there is symptomatic tonsillar herniation or syringomyelia/hydrocephalus. The main surgical treatment for CM without craniocervical instability (such as atlantoaxial luxation) is posterior fossa decompression, with or without duraplasty. The authors describe in details and in a stepwise fashion the surgical approach of patients with CM as performed at the State University of Campinas, emphasizing technical nuances for minimizing the risks of the procedure and potentially improving patient outcome.
