Case Reports
Subependymoma of the conus medullaris with cystic formation: Case report and a literature review.
Subependymoma in the spinal cord is very rare and usually occurs in the cervical cord. We report an exceptional case of subependymoma that occurred at the conus medullaris with cystic formation. This article reviews the literature on subependymoma in the conus medullaris; discusses its clinical manifestations, imaging findings, and differential diagnoses; and offers an opinion about the cystic formation of the subependymoma. ⋯ We present an extremely rare case of cystic formation in subependymoma at the conus medullaris. Subependymoma should be included in the differential diagnosis of intramedullary cystic lesions. The breakdown of the blood-brain barrier and excessive extravasation may be potential mechanisms of cystic formation.

The HOSPITAL score (HS) and LACE index (LI) are 2 validated methods for quantifying the risk of 30-day unplanned readmission after discharge. However, neither score has been validated in the neurosurgical population. This study evaluated the HS and LI in the neurosurgical population as effective predictors for 30-day unplanned readmission. ⋯ A high-risk HS and high-risk LI were predictive of 30-day unplanned readmission. Although neither score is ideal for predicting moderate risk for 30-day unplanned readmission in neurosurgical patients, both have some predictiveness that may be clinically valuable.

To assess whether mean platelet volume (MPV) is associated with functional outcome in patients with aneurysmal subarachnoid hemorrhage (aSAH). ⋯ MPV is an independent predictor of unfavorable functional outcome at 3 months in patients with aSAH.

The current data available to identify the factors associated with vertebral and carotid artery dissection in the trauma setting are conflicting, and further research is needed to accurately assess these predictors. ⋯ Positive neurological signs and the presence of cervical vertebral fractures are significant predictors for VAI. All trauma patients with cervical spine fractures and/or positive neurological findings should be considered for surveillance imaging with neck CTA and/or magnetic resonance angiography for vascular injury screening.

Microdiscectomy for lumbar disc herniation - a single center observational study.
To examine outcomes and complications following first-time lumbar microdiscectomy. ⋯ Microdiscectomy for lumbar disc herniation is an effective and safe treatment.
