Urgent surgery for spinal instability or neurological impairment caused by spinal brown tumors occurring in the context of end-stage renal disease

Spinal instability or neurological impairment caused by spinal brown tumors (BTs) with end-stage renal disease (ESRD) is an acute condition that needs urgent surgery. There is not much published information on BTs of the mobile spine given the rarity of the disease, and the literature shows inconsistent treatment options and ambiguous follow-up information. The aim of the present study was to elucidate the clinical features, anesthesia management, and surgical treatment for this rare disease through long-term follow-up observations.
