Prior studies have shown that most patients with mild traumatic brain injury or negative computed tomography (CT) scans of the head rarely decline or require neurosurgical interventions. One common reason for a delayed decline is an intracranial hemorrhage that presents within 24-48 hours. This is typically seen in elderly patients and/or patients on antiplatelet or anticoagulation agents. We describe a case of a delayed subdural hemorrhage presenting in a young adult not on any antiplatelet or anticoagulation therapy. ⋯ In rare cases, patients with negative initial head CT scans neurologically deteriorate as a result of a delayed acute subdural hematoma. We present an unusual case of a young patient on no medications with no CT findings of an intracranial injury who neurologically declined due to a delayed acute subdural hematoma.

Despite its growing popularity, no comparative studies have explored the minimum clinically important difference (MCID) of health-related quality of life scores following lumbar interbody fusion (LIF) performed on a single-level adult low-grade isthmic spondylolisthesis (LGIS). ⋯ We postulate that excessive SL does not affect lumbar lordosis; rather, it can result in lowering posterior disk height. The decrease in posterior DH may lead to a decreased foraminal height that, in turn, can lead to nerve root compression. Proper restoration of disk height and bone fusion is more important than restoration of more segmental lordosis or slip reduction for isthmic spondylolisthesis.

Case Reports
Cerebellopontine Angle Anaplastic Ganglioglioma Masquerading as Vestibular Schwannoma: Unusual Entity.
Anaplastic gangliogliomas at the cerebellopontine angle (CPA) are exceptionally rare with only a few reported cases in published literature. These are composed of atypical ganglion cells and astrocytes accounting for nearly 1% of all central nervous system tumors. The authors report the case of anaplastic ganglioglioma in an adult patient presenting as a CPA mass lesion. The presentation was bizarre, and the diagnosis was possible only after histopathologic examination of the resected mass. ⋯ This unusual appearance of anaplastic ganglioglioma has not been previously described. Neurosurgeons need to keep in mind the possibility of anaplastic gangliogliomas in the differential diagnosis of CPA lesions.

Ventriculitis is a serious complication when using external ventricular drains (EVDs). Bactericidal silver coating has been reported to reduce risk of infection. In the clinical setting, the diagnosis is often made based on symptoms and analyses of cerebrospinal fluid, with treatment initiated before infection is verified by culture. The bactericidal effect might not correlate with a reduced rate of clinically diagnosed infections. This retrospective study aimed to analyze if use of silver-coated EVDs is associated with a reduced rate of ventriculitis. ⋯ The previously reported bactericidal effect of silver-coated EVDs did not alter the clinical course to significantly reduce the number of treated cases of ventriculitis. The introduction of silver-coated EVDs cannot be motivated by reduced use of antibiotics or shorter hospital stay.

Observational Study
Cognitive Impairments After Clipping of Ruptured Anterior Circulation Aneurysms.
The cognitive impairments after treatment of ruptured aneurysms have often been underestimated. This study sought to assess their prevalence and analyze various associated factors. ⋯ Cognitive impairments are frequent after treatment of ruptured anterior circulation aneurysms. Impairments in recent memory, remote memory, and phonemic fluency are significantly greater after treatment of ACA-related aneurysms, compared with others, independent of other factors.
