Cavernous sinus hemangiomas (CSHs) are infrequent benign neoplasms. This meta-analysis was conducted with the objective of examining the prognostic outcomes of surgical interventions and radiotherapy (RT) in patients diagnosed with CSHs. ⋯ The results of this meta-analysis underscore that RT is an effective and safe treatment modality for CSHs. Furthermore, the prognostic outcomes of RT demonstrated superiority over surgical intervention.

Surgical Approach For Suprasellar Meningiomas Based On The Attachment - A Single Surgeon Experience.
Suprasellar meningiomas (SMs) can originate from midline or paramedian dura. Complexity of surgery and visual outcome depend on the attachment of SM. Conventional surgery for SM was ipsilateral to the visual deficit. We report our experience of surgical management of SM after choosing a surgical approach based on the attachment of the SM. ⋯ In patients with SM undergoing surgical resection, opting for an ipsilateral approach when the SM had a midline attachment and a contralateral approach if the SM had a paramedian attachment may ensure greater resection of the lesion and better clinical outcomes. Our findings need validation in larger, randomized studies.

This study aims to introduce a method of three-dimensional (3D) volume magnetic resonance imaging (MRI) measurements to evaluate the evolution of syringomyelia (SM) in adults with Chiari malformation type 1 (CM-1) after posterior fossa decompression (PFD), to provide reproducible and accurate measurements. ⋯ This study shows that 3D volume measurement of the syrinx cavity on MRI is a reproducible and accurate method to assess the postoperative evolution of SM in CM-1 after PFD. Most patients (75%) showed a reduction of SM volume, with a mean volume decrease of 50%. The reliability is yet to be validated in further larger studies.

The outcomes for patients with metastatic renal cell carcinoma (RCC) to the spine who underwent stereotactic body radiotherapy (SBRT) through a multidisciplinary spine oncology program are not well described. We sought to describe the clinical course and local control rates at 1 and 2 years for these patients. ⋯ In this cohort, one of the largest reported studies of spine SBRT for metastatic RCC, local control was high at 1 and 2 years. Our findings support the role of coordinated, algorithmic treatment for these patients.

To explore correlations of 3 novel radiographic parameters with myelopathy induced by posterior atlantoaxial dislocation (PAAD) secondary to os odontoideum (OO) and assess their reproducibility. ⋯ The OP/C4 SAC ratio and the C1 posterior inclination angle seem to be 2 effective and objective radiographic parameters for relating myelopathy in patients with OO with PAAD. When the OP/C4 SAC ratio is <0.93 and/or the C1 posterior inclination angle is >20°, the risk of developing myelopathy should be highly suspected in patients with OO with PAAD.
