Destruction of the spine is a huge complication of infectious spondylitis and surgical intervention is required. However, vertebral defect is a major problem after surgical intervention and numerous methods have been researched to solve this problem. There are known methods that use variously designed, patient-customized 3-dimensional (3D)-printed implants in various medical fields. The use of 3D-printed implants has also been attempted in treating defects in the spine. We present a case of failure of expandable titanium cage fusion after infection, treated using a 3D-printed implant. ⋯ A 3D-printed implant could be an acceptable and alternative treatment option for replacing a large vertebral defect.

Rathke cleft cysts (RCCs) arise from the remnant of Rathke pouch and are usually found in the intermediate lobe. In most cases, RCCs remain intrasellar and extend into the suprasellar region. Rarely, they emerge entirely into the suprasellar cistern-entirely suprasellar Rathke cleft cyst (ESSRCC). ⋯ RCCs should be considered in the differential diagnosis of suprasellar cysts. The endoscopic endonasal transtuberculum sellae approach has an advantage in visualizing these lesions owing to the direction of light from the endoscope. Headache could be treated effectively with the endoscopic endonasal transtuberculum sellae approach without recurrence of cysts or pituitary dysfunction.

The purpose of this population-based case-control study was to evaluate analgesic use after subarachnoid hemorrhage (SAH) caused by rupture of a saccular intracranial aneurysm (sIA). ⋯ Our results indicate that patients with sIA-SAH had an increased risk for new pain after sIA-SAH as compared with that of matched control population.

To investigate if the time trade-off (TTO) method reflects health-related quality of life (HRQoL) 10 years after an aneurysmal subarachnoid hemorrhage (aSAH). ⋯ Individuals willing to trade off years showed significantly poorer HRQoL; however the TTO method did not seem to fully reflect HRQoL. Most participants did not want to trade off years, despite their living with severe disability, making it difficult to fully rely on the TTO method in evaluation of medical outcome.

Case Reports
Renal Cell Carcinoma with Primary Presentation via Metastasis to the Trigeminal Ganglion.
Renal cell carcinoma (RCC) accounts for ∼8% of all brain metastatic disease; however, spread to the cranial nerves and their ganglia is uncommon. To the best of our knowledge, we report the first case of RCC metastatic to Meckel's cave, which was diagnosed secondary to new trigeminal sensory loss. ⋯ We have reported a case of RCC presenting with numbness via metastatic spread to Meckel's cave. Although uncommon, metastasis is an important diagnostic consideration for enhancing cranial nerve lesions. Our case has demonstrated that, although a history of malignancy, multiple lesions, or systemic/constitutional symptoms are typical, rare cases can demonstrate isolated central nervous system findings. Thus, short-term radiographic surveillance is indicated if the diagnosis of an intracranial or cranial nerve mass lesion is equivocal.
