The evaluation of postoperative magnetic resonance imaging (MRI) in glioma with no or minimal enhancement is controversial because the evaluation of residual tumor volume can be biased. The purpose of this study was to clarify the value of early postoperative and 3-month MRI regarding its validity in predicting recurrent disease. ⋯ Early postoperative FLAIR volume assessment in gliomas with no or minimal enhancement is susceptible to a systematic overestimation of residual tumors. Nevertheless, early FLAIR volume dynamic is an independent factor for tumor recurrence that should be evaluated in order timely adapt surveillance and therapy regimens accordingly.

This retrospective study was designed to evaluate the effectiveness of autoclaving for the prevention of surgical site infection (SSI) after cranioplasty. ⋯ Autoclaving of autologous bone causes SSI after cranioplasty and it seems to increase the risk of non-MRSA infection by normal skin flora.

Meningiomas without dural attachment (MWODA) located in the posterior fossa are an unfrequent entity. They are usually located in the fourth ventricle, and their occurrence outside of this anatomic structure is an even more uncommon finding. Chordoid meningiomas are a rare subtype of meningioma, and they have been reported to account for 0.5%-1% of all meningiomas. ⋯ We performed a thorough review of the literature, and we found 10 reported cases describing extraventricular MWODA in the posterior fossa. To our knowledge, this is the first reported case of retroclival MWODA with pathologic findings consistent with chordoid meningioma.

The sellar spine is a rare, bony growth that typically arises from the dorsum sellae. Few cases have been described in the literature thus far, and most are asymptomatic and incidentally found. We describe the case of a 19-year-old female in whom a sellar spine was noted to be associated with pituitary glandular deformation and symptomatic optic apparatus compression. ⋯ Recognition of a sellar spine can be elusive, and removal of a symptomatic one may be technically challenging. It is important to consider this entity in the differential diagnosis of a patient with headaches and bitemporal visual deficits.

Aneurysmal subarachnoid hemorrhage (ASAH) is a serious and unstable condition. Patient safety indicators (PSI) are a group of potentially preventable events in patient health care. The aim of this study is to determine the prevalence of 8 relevant PSI in a group of patients with ASAH and their relation with 2 health care outcomes. ⋯ In our study population, we found 3 PSI related to a poor outcome measured with the GOS or to a longer hospital stay: decubitus ulcer, central line-related bacteremia, and DVT. PSI have been academically considered as useful tools in clinical, epidemiologic, and research outcome scenarios. An adequate prevention protocol for these indicators could produce better outcomes in medical care for patients with ASAH.
