Spinal epidural lipomatosis (SEL) is an abnormal accumulation of unencapsulated, epidural fat. SEL can be divided into idiopathic and secondary. Secondary SEL is often associated with chronic steroid use and endocrinopathies. ⋯ SEL has been implicated in a variety of neurologic impairments and surgical decompression has been shown to prevent further worsening or result in improvement. We report a 53-year-old man with obesity and a history of chronic back pain who developed idiopathic SEL diagnosed by MRI, which subsequently resolved completely over an 8 month follow-up period. To our knowledge, this is the first reported case of complete radiographic resolution of SEL without any treatment.

We studied 25-hydroxyvitamin D (vitamin D) levels in patients with amyotrophic lateral sclerosis (ALS) and the effect of vitamin D supplementation. Vitamin D levels were checked in 37 consecutive patients with ALS. Demographic data, vitamin D supplementation, change in Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) score, and side effects from vitamin D were noted over a 9 month follow-up period. ⋯ No side effects secondary to vitamin D supplementation were reported. Vitamin D supplementation at 2000 international units daily was safe over a period of 9 months and may have a beneficial effect on ALSFRS-R scores. Further studies are warranted to determine whether there is a benefit in vitamin D supplementation for all ALS patients.

Current surgical treatments for refractory trigeminal neuralgia (TN) include microvascular decompression (MVD), percutaneous rhizotomy, and stereotactic radiosurgery (SRS). We aimed to map the trends of utilization of these procedures in the USA and examine factors associated with morbidities and discharge outcome. We performed a retrospective cohort study with time trends of patients admitted to US hospitals for TN between 1988 and 2008 who received MVD, percutaneous rhizotomy, or SRS as reported in the Nationwide Inpatient Sample. ⋯ For SRS, patient age and length of stay were found to be important by multivariate analysis on discharge. Mortality rates for MVD (0.22%), rhizotomy (0.42%), and SRS (0.12%) were low. The clinical practices for surgical treatment of TN have evolved over time with the rise of MVD and dwindling of rhizotomy procedures.

Extreme lateral interbody fusion (XLIF; NuVasive Inc., San Diego, CA, USA) is a minimally invasive lateral transpsoas approach to the thoracolumbar spine. Though the procedure is rapidly increasing in popularity, limited data is available regarding its use in deformity surgery. We aimed to evaluate radiographic correction using XLIF in adults with degenerative lumbar scoliosis. ⋯ Complications included lateral incisional hernia (n=1), rupture of anterior longitudinal ligament (n=2), wound breakdown (n=2), cardiac instability (n=1), pedicle fracture (n=1), and nonunion requiring revision (n=1). XLIF significantly improves coronal plane deformity in patients with adult degenerative scoliosis. XLIF has the ability to correct sagittal plane deformity, although it is most effective at lower lumbar levels.

Few studies detail the risk of in-hospital seizures following elective surgical or endovascular treatment of unruptured intracranial aneurysms (UIA). We compared the peri-procedural seizure incidence for clipping and coiling of UIA. A retrospective cohort study using the Australian National Hospital Morbidity Database from 1998 to 2008 was conducted. ⋯ Overall, elective surgical treatment of UIA is associated with a higher risk of seizure occurrence compared to endovascular coiling. Contrary to conventional thinking, the risk of seizures following endovascular treatment is not entirely absent. Current recommendations must be considered in relation to the issue of driving after elective intracranial aneurysm treatment.
