We investigated a simple, novel diagnostic test for detecting incomplete effort during the motor portion of the neurological examination. ⋯ The HPS test is a simple, sensitive, and very specific test for detecting incomplete effort during the motor portion of neurological evaluations.

The purpose of this study is to introduce our initial experience with the evaluation of the feasibility of using Willis covered stents (WCSs) in the treatment of complicated ophthalmic artery (OA) segment aneurysms. ⋯ WCSs may provide an alternative solution for treating complex OA segment aneurysms by reconstruction and preservation of the ICA. Our study also confirms the safety, efficacy, and midterm durability of WCSs for complex OA segment aneurysms.

Patients undergoing surgical resection of meningioma are at increased risk for developing venous thromboembolism (VTE). The aim of this study was to assess occurrence of VTE in patients who underwent surgical resection of meningioma to determine risk factors and associated complications of VTE. ⋯ Risk factors of VTE and associated complications were identified. Understanding these risk factors provides physicians with further insight in managing this subgroup of patients in a personalized fashion in the perioperative period to minimize the incidence and morbidity of VTE.

Navigated Transcranial Magnetic Stimulation In A Patient With A Cranioplasty In Situ: A Safe And Accurate Procedure.
Navigated transcranial magnetic stimulation (nTMS) is a nonsurgical mapping technique used in mapping of motor and language eloquent areas within and/or surrounding brain tumors. Previous reports support this as a safe technique with minor side effects associated with minor headaches and discomfort around the stimulation area. Currently there are no published reports concerning the accuracy and safety of this procedure in patients with a titanium cranioplasty in situ. ⋯ This report confirms that nTMS is a safe and accurate procedure in patients who have a titanium cranioplasty in situ.

Extracerebral neuroglial heterotopias are rare manifestations of cerebral tissue outside the brain whose most common form is the so-called nasal glioma. In this case report we illustrate the first case of heterotopic neuroglial tissue within the bone of the skull. ⋯ The pathogenesis of cerebral heterotopias is diverse. Most of the midline lesions are probably residuals of former meningoencephaloceles. The pathogenesis of extracranial nonmidline lesions is more questionable. Their cause might be a former trauma, inflammatory disease, or surgery. Another option is that they represent primary neuroglial heterotopias, as it is supposed for manifestations of the lung. The coexistence of a heterotopia and a meningioma in this case is probably a coincidence. It is also debatable whether the broad tumor extension within the bone and/or the heterotopia might go back to alterations of the bone structure.
