This study examined the use of noninstrumented posterolateral lumbar fusion with bone morphogenetic protein (BMP) and compared its effectiveness with that of instrumented fusion for the treatment of lumbar spinal stenosis (LSS) with spondylolisthesis in elderly patients. ⋯ Noninstrumented posterolateral lumbar fusion with rhBMP-2 in elderly patients with LSS and spondylolisthesis is a viable alternative to instrumented fusion based on clinical outcomes measured in this study.

Quality Improvement (QI) is essential for improving health care delivery and is now a required component of neurosurgery residency. However, neither a formal curriculum nor implementation strategies have been established by the Accreditation Council for Graduate Medical Education. ⋯ A formal didactic curriculum and practical application of QI methodologies adds value to resident training. Further, it has the potential to positively impact practice. Consideration should be given to adopting a formal QI curriculum by other neurosurgery departments and perhaps standardization on national level.

The BAT score is a novel prediction score of hematoma expansion based on noncontrast computed tomography (CT) and consists of the blend sign, hypodensities, and time interval from onset to CT. This study aimed to compare the BAT score and the spot sign on CT angiography in a cohort of patients with spontaneous intracerebral hemorrhage. ⋯ The BAT score based on noncontrast CT is a good predictor of hematoma expansion. When CT angiography spot sign is unobtainable, the BAT score can be used to predict hematoma expansion.

Acromegaly caused by Rathke cleft cyst (RCC) mimicking a plurihormonal pituitary adenoma (PA) is rare. ⋯ We reported a rare case of acromegaly caused by RCC mimicking a plurihormonal PA. This case suggests that inflammation associated with RCC might be involved in the development of adenomatous cells. Postoperative clinical symptoms and elevated fibrinogen and IGF-1 levels later improved. This outcome suggested that the transient increase in IGF-1 2 months after surgery might reflect RCC-induced inflammation.

To compare the clinical and radiologic outcomes of 3 anterior surgical techniques for the treatment of 3-level cervical spondylotic myelopathy (CSM) and the evolution of intramedullary T2-weighted increased signal intensity (ISI). ⋯ For patients with 3-level CSM with ISI on T2-weighted MRI, HDF can be considered as the optimal technique that achieves better clinical and radiologic outcomes than the ACDF or ACCF procedure. HDF also has a better postoperative regression of ISI compared with the ACDF or ACCF procedure, which may potentially be an important indicator for improving surgical outcomes.
