Sciatic neuralgia (SN) is a type of pain commonly associated with lumbosacral radiculopathy. May-Thurner syndrome (MTS) is a disease characterized by venous congestion in the left common iliac vein (LCIV) due to right common iliac artery compression. A case of MTS with SN as the first presenting symptom is described. ⋯ This is the first report of SN associated with MTS. MTS should be considered as one of the differential diagnoses of SN. Thus, symptoms such as pain, edema, and skin hyperpigmentation on the left leg should be closely noted.

Case Reports
Delayed Intraventricular Pneumocephalus Following Shunting for Normal-Pressure Hydrocephalus.
Pneumocephalus is usually seen in trauma or cranial surgery. It is rarely reported as a delayed complication of ventriculoperitoneal shunt placement for hydrocephalus secondary to trauma, tumor, or aqueduct stenosis. We describe a case of intraventricular pneumocephalus manifesting 10 months after placement of a shunt for normal-pressure hydrocephalus. ⋯ Pneumocephalus after shunting for NPH is rare and described as a complication only during the first 2 postoperative months. This case is unique, as the pneumocephalus developed 10 months after shunting. The combination of an occult, possibly congenital, skull base defect and the insertion of a shunt resulted in delayed intraventricular and intraparenchymal pneumocephalus.

Pediatric posterior circulation aneurysms are rare, complex, poorly understood lesions on which only limited literature is currently available. We report our 12-year experience of managing this condition to enhance knowledge of this rare entity. ⋯ Vertebrobasilar junction and vertebral artery was the most common location for posterior circulation aneurysms and most were dissecting aneurysms. Endovascular treatment was the mainstay of management. Overall good outcome was observed at long-term follow-up.

To evaluate a new technique in brainstem surgery, neuronavigation (NN)-guided corticospinal tract (CST) mapping, in a retrospective study of patients undergoing brainstem tumor surgery. ⋯ Brainstem tumor resection using NN-guided CST mapping achieved better preservation of motor function compared with routine NN and IONM. NN-guided CST mapping not only decreased the difficulty of the surgery, but also significantly improved the efficiency of surgery.

Ventriculostomy-associated cerebrospinal fluid infection (VAI) is a major complication limiting the use of an external ventricular drain (EVD) in treating patients with intraventricular hemorrhage (IVH). Risk factors of VAI are still under wide discussion. ⋯ Patients with a high mGS are vulnerable to VAI. Bilateral EVD may be an appropriate treatment option for patients with a high mGS, but might increase the risk of infection in those with a low mGS.
