Comparison of outcomes of different osteotomy sites for hallux valgus: A systematic review and meta-analysis.

Background: Hallux valgus (HV) is a common foot deformity for which several corrective surgical procedures, with different osteotomy sites, have been reported. The purpose of the present study was to systematically review randomized (RCTs) or controlled (CCTs) clinical trials and perform meta-analysis on outcomes of different osteotomy sites of the first metatarsal.

Methods: An extensive literature search was conducted in PubMed and the Cochrane Library from January 1983 to July 2020.

Unusual imaging characteristics of cystic meningioma in cerebellopontine angle.

We report a case of cystic meningioma at the left cerebellopontine angle (CPA). Magnetic resonance imaging demonstrated both solid and cystic components in the tumor. The cystic component appeared slightly hyperintense compared to cerebrospinal fluid on fluid-attenuated inversion recovery (FLAIR) imaging.

Different hemodynamics of basal ganglia between moyamoya and non-moyamoya diseases using intravoxel incoherent motion imaging and single-photon emission computed tomography.

Background: Moyamoya disease (MMD) and non-MMD have different pathogenesis, clinical presentation, and treatment policy.

Purpose: To identify differences in hemodynamics between MMD and non-MMD using intravoxel incoherent motion (IVIM) magnetic resonance imaging (MRI) and single-photon emission computed tomography (SPECT).

Material And Methods: Patients who had undergone Tc-ECD or I-IMP SPECT, and IVIM imaging were retrospectively studied.
