Review Case Reports
Managing a rare Malignant Sweat gland tumour invading the Brain: Case report and literature review.
Malignant sweat gland adnexal tumors are rare with an incidence of 0.001%. Of these, clear cell hidradenocarcinoma is an extremely uncommon subtype that accounts for 6% of malignant eccrine sweat gland tumors. They occur commonly in the head, neck, and extremities. Although they have a propensity for local recurrence, intracranial extension with brain invasion is extremely rare. ⋯ We report a rare indolent case of clear cell hidradenocarcinoma invading the brain, which was managed with near-total decompression and adjuvant radiotherapy. Intracranial extension in such aggressive tumors poses challenges in management, and regular neuroimaging surveillance is advised.

Review Meta Analysis
Application of Ultrahigh Field MRI in the Treatment of Brain Tumors: a Meta-analysis.
Magnetic resonance imaging (MRI) is the imaging modality of choice for the clinical management of brain tumors, and the majority of scanners operate with static magnetic field strengths of 1.5 or 3.0 Tesla (T). During the past decade, ultrahigh field (UHF) MRI has been investigated for its clinical applicability. This meta-analysis evaluates studies pertaining to the application of UHF MRI to patients with brain tumors. ⋯ UHF MRI shows promise to improve detection and characterization of brain tumors, preoperative planning for neurosurgical resection, and longitudinal monitoring of the effects of radiation and antibody-based therapies. Technical innovations are needed to overcome field inhomogeneity and susceptibility artifacts in certain regions of the skull. Finally, larger studies comparing 1.5 T, 3.0 T, and 7.0 T or greater will determine whether UHF MRI gains acceptance as a clinical standard.

Review Case Reports
Glioblastoma with Rhabdoid Features: Report of Two Young Adult Cases and Review of the Literature.
There are few previous reports of glioblastoma in young adults, in particular, of the very rare recently proposed rhabdoid or epithelioid types. ⋯ Glioblastoma with rhabdoid features may represent a specific pattern of clinical progression that emerges from histologic glioblastoma types.

Multicenter Study
Can a Minimal Clinically Important Difference Be Achieved in Elderly Patients With Adult Spinal Deformity Who Undergo Minimally Invasive Spinal Surgery?
Older age has been considered a relative contraindication to complex spinal procedures. Minimally invasive surgery (MIS) techniques to treat patients with adult spinal deformity (ASD) have emerged with the potential benefit of decreased approach-related morbidity. ⋯ MCID represents the threshold at which patients feel a meaningful clinical improvement has occurred. Our study results suggest that the majority of elderly patients with modest ASD can achieve MCID with MIS.
