From: Understanding a mass in the paraspinal region: an anatomical approach
Cold abscesses in a 37-year-old male with mild thoracic pain, weight loss and fatigue for 1Â month. Axial (a) and sagittal (d) T1WI with contrast agent show large left paraspinal abscesses, which extend in both hypaxial and epaxial (superficial and deep) regions. Abscesses extend along the vertebral body to the contralateral side (white arrowheads) and into the left vertebral foramen (black arrowhead). Axial CT scan reconstruction (c) and anteroposterior radiograph (e) show septic arthritis of the costovertebral joint and spondylitis (white arrows). Anteroposterior radiograph shows the left hypaxial mass along the left side of the side (black arrows). As the lesion was superficial, US was used for percutaneous guided biopsy (b). US shows a hypoechoic mass with posterior acoustic enhancement
