Imaging features of chronic recurrent multifocal osteomyelitis (CRMO) involving the vertebral column of a lemur with subsequent paraplegia due to pathological fractures

摘要

A seven-year-old, female ring-tailed lemur was referred for progressive non-ambulatory paraplegia. A computed tomographic (CT) scan of the whole body revealed multifocal lytic le-sions involving multiple vertebrae and several pathological vertebral fractures. Necropsy and histopathology identified pyogranulomatous osteomyelitis. The imaging and histopathological findings resemble chronic recurrent multifocal osteomyelitis described in human medicine.
