Case Reports
Impact of surgical correction of a U-shaped sacral fracture on sagittal spino-pelvic alignment: Regarding one case.
U-shaped sacral fractures are uncommon and are mostly the consequence of a high-energy kinetic trauma. The sacrum is a crucial element for sagittal alignment in a standing position as it determines the value of the pelvic incidence, which is a fixed and unchanging parameter for a given individual. We report the case of a 21-year-old man who underwent corrective surgery for a type II U-shaped fracture of the sacrum (according to the Roy-Camille classification), associated with a S1-S2 dislocation and sacral kyphosis that modified the patient's pelvic incidence. ⋯ The surgery was managed for neurological decompression, stabilization of the fracture and correction of sacral kyphosis. The restoration of the theoretical pelvic incidence depended on the estimated lumbar lordosis. The aim of this study was to highlight the particularities in the management of a sacral U-shaped fracture and their relationship with the sagittal alignment.

Vascular lesions of the spinal cord are increasingly recognized. The most common types of these lesions are dural arteriovenous fistulas (AVFs) whereas, extradural AVFs are a very rare type of spinal AVF and can be associated with either extradural or intradural venous reflux. This results in neurological deficits through congestive or compressive myeloradiculopathy. These lesions must be treated to allow stabilization or improvement of neurologic status, either by endovascular therapy or microsurgical interruption. However, because some patients are not amenable to endovascular treatment, surgery is often warranted, which usually involves hemi- or bilateral laminectomy following a midline approach with bilateral muscle stripping. The main drawback of this procedure is directly related to the morbidity of the approach. Although, minimally invasive approaches are likely to overcome this drawback, there is a lack of reported experience supporting their use for treating spinal dural AVFs. ⋯ The minimally invasive surgical treatment of spinal AVFs with epidural venous reflux is safe and effective. This approach is a valuable alternative to endovascular therapy and the standard open microsurgical approach.

Review Case Reports
Spinal cord compression due to a primary vertebral hydatid disease: A rare case report in metropolitan France and a literature review.
Bone echinococcosis or bone hydatidosis is mainly caused by the larva of a dog taenia, Echinococcus granulosus. We described a rare imported case in metropolitan France of spinal cord compression from a primary vertebral hydatidosis. ⋯ Bone echinococcosis is rare and represents about 2% of hydatidosis. The spine localization is found in half of the cases. This pathology particularly occurs in the Eastern and Southern countries of Mediterranean sheep breeding areas, but still rare in metropolitan France. Spinal cord compression is a frequent presentation of spinal hydatidosis but neurological symptoms are various and non-specific. The reference treatment is removal surgery with particular precautions, followed by an anti-parasitic chemotherapy (albendazole) to limit recurrences. However, a long-term follow-up is mandatory due to later recurrences.

To depict the outcome of patients with WHO grade III meningioma and identify factors that may influence the survival. ⋯ This series highlights the poor prognosis associate with the diagnosis of malignant meningioma. Patients with primary WHO grade III meningioma demonstrating less than 14 mitosis per 10 high power fields may live longer. We could not confirm the usefulness of complete resection and adjuvant radiotherapy.

Vagoglossopharyngeal neuralgia is a rare pathology whose atypical forms, dominated by syncopal manifestations, are still rarer. Although the territory of the vagus nerve involves, beyond the cardiovascular system, the respiratory and the digestive systems, there is no report in literature of atypical forms other than syncopal. Therefore, the authors were prompted to report the case of a patient whose vagoglossopharyngeal neuralgia was predominantly revealed by digestive symptoms. ⋯ One year after the surgery, the patient was free from all painful and digestive symptoms. A survey of the literature did not find any reference to digestive symptoms together with the neuralgia; only a syncopal type of cardiac symptoms related to the parasympathetic nervous system were described. The hypothesis was that the revealing digestive symptoms are linked to a similar parasympathetic mechanism, implying the visceral component of the Xth cranial nerve.
