Traditional approaches to medial temporo-occipital intra-axial brain tumors carry the risk of visual or language deficits related to brain retraction or transgression of deep fiber tracts. To reduce these risks, the microscopic supracerebellar transtentorial approach with the patient in the sitting position has been previously described for lesions in relative proximity to the tentorium. ⋯ This small series suggests that the endoscopic supracerebellar transtentorial approach with the patient in the sitting position can be a safe and effective approach for removing medial temporo-occipital lesions. It allows excellent tumor visualization, eliminates the need for brain retraction, minimizes parenchymal transgression, and improves surgical ergonomics. Significant experience in endoscopy and excellent neuroanesthesia support are recommended before undertaking this approach.

Occurrence of spinal epithelioid sarcomas is rare, with few cases reported in the literature. Although wide local resection is the recommended treatment, this technique is challenging in the spine. ⋯ ES, epithelioid sarcomasMEP, motor evoked potentialSSEP, somatosensory evoked potential.

Recent research on radiation exposure in minimally invasive surgery for transforaminal lumbar interbody fusion (MIS TLIF) has led to the development of a low-dose radiation fluoroscopy protocol, with resulting reductions in fluoroscopy times and radiation exposures. ⋯ AP, anteroposteriorBMI, weight in kilograms divided by height in meters squared (kg/m)kVp, kilovoltage potentialMIS, minimally invasive surgeryMIS TLIF, minimally invasive surgery for transforaminal lumbar interbody fusionODI, Oswestry Disability IndexTLIF, transforaminal lumbar interbody fusionVAS, visual analog scale.
