There is a strong relationship between lower back pain and paraspinal muscle atrophy. In this study, we aimed to investigate the prevalence of lumbar paravertebral muscle atrophy in patients with and without single-level disc herniation. ⋯ The MM and erector spinae muscle groups are innervated by the dorsal root of the spinal nerve arising from the same level; therefore, long-term pressure on the root caused by disc herniation can cause atrophy and degeneration of that muscle group.

Numerous studies have demonstrated the importance of gross total resection in improving patient survival in glioblastoma (GBM). Advances in surgical tools and techniques such as intra-operative imaging, fluorescent agents, and functional imaging sequences are allowing for better identification of tumor borders and vital eloquent cortex in order to safely achieve higher rates of complete resections. Furthermore, due to the limits of surgical resection alone, new minimally invasive techniques for treatment of GBM are under development. These advances are crucial for improving neurosurgical care and outcomes in this difficult patient population.

Muscle injury is inevitable during surgical exposure of the spine. This study compared paraspinal muscle injury after 4 surgical techniques: microdiscectomy (MD), percutaneous endoscopic lumbar discectomy (PELD), percutaneous endoscopic interlaminar discectomy (PEID), unilateral biportal endoscopic discectomy (UBED). ⋯ PELD is the least invasive spinal surgical technique.

Moyamoya vasculopathy (MMV) is characterized by progressive stenosis of the intracranial arteries. MMV currently has no curative treatments, and cerebral ischemia and hemorrhage are the major outcomes. Evaluation of the stroke risk of each patient resulting from the progression of intracranial arterial stenosis is clinically important. ⋯ Arterial vessel wall enhancement in MMV patients was closely related to progression of intracranial arterial stenosis. Strong enhancement of the intracranial vessel wall was associated with intracranial arterial stenosis progression, and lack of enhancement correlated with the stability of intracranial arterial stenosis.
