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.

Surgical resection of intramedullary tumors remains technically challenging. The role of intraoperative ultrasound and contrast-enhanced ultrasound (CEUS) in these surgeries has not yet been well defined. This study was aimed to evaluate the potential of intraoperative ultrasonography, especially CEUS, in visualizing intramedullary spinal cord tumors, and to assess the values for improving surgical outcomes. ⋯ Intraoperative ultrasound is of great value for localizing lesions and determining the extent of dural opening and myelotomy, therefore reducing the invasiveness of spinal surgery for intramedullary tumors. CEUS helps to delineate the tumor margins and perfusion features.

Review Case Reports
Trochlear schwannoma arising from transition zone of nerve sheath in the pineal region: Case report and review of the literature.
This report presents the third case of trochlear schwannoma arising from the pineal region and the first case to be resected using a paramedian infratentorial supracerebellar approach. Schwannomas of cranial nerves have traditionally been thought to arise from the transitional point where the axonal envelopment switches from glial cells to Schwann cells; however, recent temporal bone histopathologic evidence from vestibular schwannomas challenges this view. Of the 38 cases of pathology-confirmed trochlear schwannoma in the literature, there are only 2 cases arising from the pineal region, where the nerve sheath transition zone is located. Here, we discuss an unusual case of trochlear schwannoma arising from this transition zone. ⋯ Trochlear schwannoma should be considered when a mass is identified in the pineal region. This diagnosis should still be entertained for mass lesions along the free tentorial edge because the tumor may arise distant from the glial-Schwann transition zone located by the dorsal midbrain. We propose a treatment algorithm for this rare tumor that seeks to maximize functional outcome.
