Multicenter Study
COVID 19 associated Rhino-orbito-cerebral Mucormycosis - A multi-institutional retrospective study of imaging patterns.
Mucormycosis infection of the maxillofacial region and brain has been associated with coronavirus disease 2019 (COVID-19) infection. Mucormycosis was relatively a rare infection before COVID-19, and imaging findings are not very well described. ⋯ We describe the imaging findings in the largest cohort of patients with rhino-orbito-cerebral mucormycosis in the context of the current COVID-19 pandemic. A simplified staging system described here is helpful for standardized reporting and carries prognostic information.

Case Reports
Surgical Technique and Nuances of Resection of a Trochlear Schwannoma: An Operative Video.
Cranial nerve schwannomas accounts for around 8% of all benign intracranial tumors, arising most commonly from the vestibular nerve, followed by the trigeminal nerve and other lower cranial nerves. However, trochlear schwannoma in a patient without neurofibromatosis-2 are extremely rare and to date, fewer than 100 cases have been reported in the literature. They are either asymptomatic or present with ophthalmologic or neurologic symptoms. ⋯ Hence she underwent left retromastoid suboccipital craniectomy, lateral supracerbellar approach, and complete excision of the tumor. Postoperatively the patient had an uneventful recovery without any new neurologic deficits. At 6 months' follow-up the patient is doing well.

We assessed the readability of spine-related patient education materials on professional society websites to determine whether this had improved since last studied. We also compared the readability of these materials to a more patient-centered source, such as WebMD. ⋯ The average readability of spine-related topics exceeded the eighth grade reading level. The AAOS resources had better readability compared with the NASS and AANS. We found no improvement in readability since last studied. The readability of professional societies' materials was significantly worse than those from WebMD.

Infantile choroid plexus papilloma (CPP) associated with multiple peritumoral cysts is a rare variant of CPP, and clinical course and optimal management are largely unknown. A 9-month-old boy presented with a large solid tumor in the left lateral ventricle associated with multiple peritumoral cysts, arachnoid cysts, and hydrocephalus containing xanthochromic fluid with high protein content. ⋯ Follow-up magnetic resonance imaging 12 months after surgery revealed that these cysts remained stable. CPP with nonenhancing peritumoral cysts can be managed by resection of only the solid part of the tumor without permanent cerebrospinal fluid diversion.

Randomized Controlled Trial
Use of three-dimensional printed brain models during deep brain stimulation surgery consultation for patient health literacy: a randomized controlled investigation.
Advanced therapies in neurosurgery, such as deep brain stimulation (DBS), would benefit from improved patient education materials. Three-dimensional (3D) printed anatomical models represent a recent development for improving patient education for neurosurgical procedures. ⋯ In the first randomized controlled study to our knowledge of 3D printed models for DBS consultation, our results demonstrate that patients had improved understanding of their therapy with the models. However, the models alone did not affect risk evaluation or comfort with surgery. A 3D printed brain model may help improve patient understanding of DBS surgery.
