Instability of the craniovertebral junction (CVJ) following odontoidectomy is relatively common. Traditionally, separate stage posterior atlantoaxial ± occipitocervical fusion is used for treatment. A transmucosal approach using a clean-contaminated route is associated with hypothetical risks of infectious complications. ⋯ Five (1.16%) patients required removal of their anterior fixation device, 4 (0.93%) related to SSI. ORs comparing our results with Medvedev et al's retrospective National Surgical Quality Improvement Program study assessing the risk associated with posterior cervical fixation showed no statistical difference between postoperative infection rates (OR = 0.72, P = 0.36). An extensive review of the literature found no evidence to suggest placement of spinal hardware via transmucosal corridor is associated with an increased risk of SSI.

Multicenter Study
Combination of Ultraearly Hematoma Growth and Hypodensities for Outcome Prediction after Intracerebral Hemorrhage.
Noncontrast computed tomography hypodensities (HD) and ultraearly hematoma growth (uHG) are reliable markers for outcome prediction in patients with spontaneous intracerebral hemorrhage (sICH). The present study aimed to assess whether the combination of these 2 markers could improve the prognostic value for sICH. ⋯ The combination of uHG and HD improves the stratification of unfavorable prognoses in patients with sICH.

Over the last decades, significant advancements have been achieved in the treatment of pediatric brain tumors as a result of radiation therapy (RT). With the increasing diffusion of this treatment, iatrogenic damage to cerebrovascular tissues contouring the radiation target volume has become the subject of debate, especially radiation-induced moyamoya syndrome (RIMS). ⋯ Pediatric patients receiving involved field RT for the treatment of brain tumors have an increased risk of developing RIMS. Prompt diagnosis and early surgical revascularization play a pivotal role in decreasing the clinical impact of this complication. The use of new techniques, such as the intensity-modulated RT, and the increasing dose saving for the organs at risk, are essential to prevent iatrogenic vasculopathy. The combination of appropriate medical therapy and surgery will improve patient management and clinical outcome.

Iatrogenic ureteral injury associated with lumbar spine surgery is an uncommon but devastating complication with associated medicolegal implications. ⋯ Ureteral injury associated with lumbar spine surgery is overreported in developed or developing countries. It should be considered in the differential diagnosis of any patient who presents with symptoms of acute abdomen after lumbar spine surgery, and patients who underwent restorative surgery had a good prognosis.

Diffuse leptomeningeal glioneuronal tumor (DLGNT) is a recent addition to the World Health Organization classification schema of brain tumors, under the heading of neuronal and mixed neuronal-glial tumors. DLGNTs have a classic imaging appearance. However, it has often been misdiagnosed owing to its rarity, its resemblance to granulomatous/leptomeningeal etiologies, and the clinical presentation. ⋯ We have described the classic imaging appearance of this rare brain tumor. Radiologists and clinicians should be aware of this entity to avoid misdiagnosis and a delay in management.
