Rapid progression of metastatic non-small cell lung cancer (NSCLC) after discontinuation of tyrosine kinase inhibitors or anaplastic lymphoma kinase (ALK) inhibitors has been described and is associated with a poor prognosis. We describe the first reported case of accelerated NSCLC tumor extension throughout the entire spinal epidural space. ⋯ The differential diagnosis when evaluating presumed spine epidural abscess should include tumor and metastatic disease, even in cases of rapid development. Recent termination of tyrosine kinase inhibitors or ALK inhibitors may result in severe disease flares, and a history of such should raise clinical suspicion for metastatic progression. In addition to cultures, biopsy for pathologic diagnosis should be collected during decompressive surgery.

Posterior lumbar fusions are performed to treat various spinal deformities, degenerative diseases, fractures, infections, and tumors. The possibility of episode-based bundled payments for spine surgery necessitates analysis of the factors predicting readmissions and postoperative complications. ⋯ Nonhome discharge patients experienced higher rates of complications and 30-day readmissions.

This study sought to determine whether a relationship exists between caudal instrumented level and revision rates, neck disability index scores, and cervical alignment in patients undergoing multilevel posterior cervical fusion. ⋯ This study suggests that constructs terminating in the proximal thoracic spine have similar revision rates, postoperative neck disability index scores, and radiographic measurements as those terminating in the cervical spine. Poor cervical alignment, as evidenced by increased sagittal vertical axis, cervical kyphosis and T1 slope, predicts need for revision and of poorer clinical outcomes.

Case Reports
A pial arteriovenous fistula in infancy as the presenting manifestation of hereditary hemorrhagic telangiectasia.
Pial arteriovenous fistulas (PAVFs) are rare, accounting for 1.6%-4.7% of all intracranial vascular malformations. Often diagnosed in childhood, about 30% are associated with hereditary hemorrhagic telangiectasia. A case of PAVF diagnosed soon after birth and given cerebrovascular therapy 4 months after birth is reported. ⋯ This report describes a case of infant PAVF with heart failure, a giant varix, hydrocephalus, and intraventricular hemorrhage treated by TAE using platinum coils and liquid embolic material.

Adult spinal deformity (ASD) operations are complex and often require a multisurgeon team. Simultaneously, it is the responsibility of academic spine surgeons to train future complex spine surgeons. Our objective was to assess the effect of resident and fellow involvement (RFI) on ASD surgery in 4 areas: 1) perioperative outcomes, 2) length of stay (LOS), 3) discharge status, and 4) complications. ⋯ RFI in ASD surgery was associated with increased operative time, the need for additional transfusions, longer LOS, and nonhome discharge. However, no increase in major, minor, or severe complications occurred. These data support the continued training of future deformity and complex spine surgeons without fear of worsening complications; however, areas of improvement exist.
