Imaging diagnosis-infiltrative lipoma causing spinal cord and lumbar nerve root compression in a dog

Vet Radiol Ultrasound. 2013 Jul-Aug;54(4):381-383. doi: 10.1111/vru.12038. Epub 2013 Apr 12.


A 12-year-old, male, fox terrier dog presented with an abnormal gait of the left pelvic limb. Computed tomography revealed a large, homogeneous, hypoattenuating, noncontrast enhancing mass within the left epaxial muscles that invaded the L5-6 vertebral canal and caused spinal cord compression. Imaging findings were consistent with an infiltrative lipoma. The mass was removed and a left hemilaminectomy was performed in the affected area. Histopathology confirmed the mass to be an infiltrative lipoma. The dog recovered and regained neurologic function within 2 weeks. Computed tomography assisted preoperative planning by characterizing the shape, size, and location of the mass.
