Primary non-Hodgkin's lymphoma arising from the skull base (PLSB) is a rare entity most commonly subclassified as diffuse large B-cell lymphoma (DLBCL). This lesion often arises from the clivus and demonstrates a cranial nerve (CN) VI palsy. In this case report and literature review, we document the clinical presentation and management of a case of clival DLBCL, along with a review of current literature pertaining to DLBCL of the skull base. ⋯ DLBCL arising from the skull base often originates from the clivus and results in CN VI palsy. Current publications indicate a unique clinical presentation and immunohistochemical profile. Treatment generally involves biopsy, followed by chemo- and/or radiotherapy.

Double crush syndrome (DCS) is defined as multiple sites of compression along a single nerve. The combination of a compressive proximal lesion in the lumbar spine and a distal common peroneal nerve entrapment may result in compound nerve dysfunction. ⋯ This is the first series to report DCS with two active points of compression in the lumbar spine and lower extremity based on EMG and imaging findings. Common peroneal nerve decompression was found to improve average dorsiflexion strength.

To investigate the effect of intravertebral cleft sclerosis on the efficacy of percutaneous vertebroplasty (PVP) in osteoporotic vertebral compression fractures (OVCF). ⋯ IVCs affect cement distribution and recovery outcomes, with IVCns achieving better results. Early treatment is advised for OVCF with intravertebral clefts.

Cervical spinal stenosis most commonly occurs at the subaxial spine. C1-C2 stenosis is relatively unusual but can be present in certain congenital or syndromic conditions such as rheumatoid arthritis. ⋯ Decompression and stabilization of the segment were performed. This case is unique as this pathology occurred at an uncommon location, leading to an unusual degree of compression and resulting in surgical intervention.
