Abstract: Aneurysmal bone cysts (ABC) are rare, benign primary bone tumors that can be fast-growing and locally destructive]. It can represent an aggressive lesion and often requires surgical resection as treatment. Although rare, ABCs are expansile entities that can cause significant osteolytic destruction of bone and surrounding tissue. This report illustrates a case of a 32-year-old female who presented to the emergency department with chronic worsening low back pain without other significant neurological deficits. Radiographic investigations revealed a large expansile mass arising from the thoracic spine invading into the central canal. A biopsy was performed and histopathology revealed ABC. This case highlights the importance of including ABCs in the differential of patients with insidious musculoskeletal complaints without apparent neurological symptoms. While it is a rare condition, it is important to be cognizant of its possible clinical presentations and radiographic features in order to diagnosis the disease and arrange for appropriate management.Summary: Aneurysmal bone cysts, along with slow growing/benign or locally aggressive lesions, are important differentials to consider when presented with chronic nonspecific pain. We present a case of thoracic spine ABC causing critical central canal stenosis but with no clinical neurological findings. References: 1. Mesfin, A., McCarthy, E. F., & Kebaish, K. M. (2012).
