Posterior cranial fossa (PCF) hemangioblastomas are benign, highly vascularized, and well-differentiated tumors with well-described histopathologic features. Although relatively rare, this tumor is the most prevalent primary tumor of the cerebellum in adults. ⋯ The literature of adult PCF hemangioblastomas is limited and general surgical experience with such tumors is scarce because of their rarity. Rates of postoperative complications and mortality remain higher than expected. However, prognosis and surgical outcomes are generally favorable. Nevertheless, surgery of adult PCF hemangioblastomas is a demanding and challenging task.

Review Case Reports
Presacral Tarlov cyst as an unusual cause of abdominal pain: new cases and literature review.
A presacral Tarlov cyst is an unusual cause of abdominal pain. The unusual location of a presacral Tarlov cyst can lead to misdiagnosis and inappropriate treatment. To guide appropriate diagnosis and treatment, we reviewed causes, clinical presentations, radiologic features, and management options of this extremely rare lesion. ⋯ Although extremely rare, presacral Tarlov cysts should be suspected in patients with abdominal pain, especially when pain occurs along with other neurologic symptoms. This review provides a systematic description of this rare disease, which may be helpful in guiding the appropriate diagnosis and treatment.

Review Case Reports
Atlantooccipital Rotatory Dislocation: A Case Report and Systematic Review.
Atlanto-occipital rotatory dislocation (AORD) has rarely been reported in the literature; for this reason, the clinicoradiologic characteristics of this injury are not well described. ⋯ Compared with previously classified atlanto-occipital dislocations, AORD is an independent and unique variation. AORD presents with different biomechanical, clinicoradiologic, and prognostic characteristics and represents an important addition to the spectrum of atlanto-occipital dislocation injuries.

Review Case Reports
Malignant cerebral swelling after a cranioplasty: a case report and literature review.
Cranioplasty is considered a low-risk operation in the field of neurosurgery following decompression craniectomy. Well-known complications after cranioplasty, such as infection, seizure, and titanium plate exposure, may not threaten the lives of patients. Unfortunately, there are many fatal complications that are underreported. In this study, we report a case and perform a literature review to introduce malignant cerebral swelling, which is regarded as a devastating complication. ⋯ Cranioplasty is a high-risk procedure in some cases. Sinking skin flap syndrome and vacuum suction drain may be the main risks of a postoperative venous congestion and stasis, which may result in diffuse cerebral swelling. Once the computed tomography scan shows malignant cerebral swelling, the patient is expected to have a poor prognosis.

Multicenter Study
Effect of Smoking Status on Successful Arthrodesis, Clinical Outcome, and Complications After Anterior Lumbar Interbody Fusion (ALIF).
Anterior lumbar interbody fusion (ALIF) is a surgical technique indicated for the treatment of several lumbar pathologies. Smoking has been suggested as a possible cause of reduced fusion rates after ALIF, although the literature regarding the impact of smoking status on lumbar spine surgery is not well established. This study aims to assess the impact of perioperative smoking status on the rates of perioperative complications, fusion, and adverse clinical outcomes in patients undergoing ALIF surgery. ⋯ The rate of successful fusion after ALIF surgery was found to be significantly lower for smokers compared with nonsmokers. No significant association was found between smoking status and other perioperative complications or adverse clinical outcomes.
