Paravertebral soft tissue swelling or abscess

Introduction Anterior and parasitic soft tissue swelling or abscess is one of the important features of the diagnosis and differential diagnosis of spinal tuberculosis, especially the calcification of abscess is often specific.

Cause

Common in spinal tuberculosis, vertebral body and attachment damage extensive and serious cases.

The anterior and posterior abscesses were mostly symmetrically distributed, and the thickest part was generally more than 1 cm (the average thickness of the group was 1.5 cm), and the range of abscess flow often exceeded the range of the diseased vertebral body. Spinal tuberculosis paraspinal abscess has two manifestations:

1 paraspinal abscess: pus is collected in the vertebral body, can be in front, back and sides, to accumulate on both sides and front more; pus will pick up the periosteum, can also spread up and down along the ligament gap It causes bone erosion on the edges of several vertebral bodies. It can also enter the spinal canal to the rear, compressing the spinal cord and nerve roots.

2 flow abscess: after the paravertebral abscess accumulates to a certain amount, the pressure increases, will penetrate the periosteum, flow down the myofascial space, and abscesses in the area away from the lesion; for example, psoas abscess, axillary abscess, Lumbar deltoid abscess and deep abscess at the groin.

The degree of swelling of the soft tissue of the paravertebral soft tissue is different. It is characterized by localized thickening of the soft tissue adjacent to the invading vertebrae, oval or round mass, uniform density, and enhanced thin wall envelope.

Differential diagnosis

Spinal tuberculosis is the most common clinical, accounting for the first place in the body of bone and joint tuberculosis. 99% is vertebral tuberculosis. Vertebral tuberculosis accounts for about 50% to 75% of all bone and joint tuberculosis patients. The lumbar vertebrae are the most common in the vertebral tuberculosis, followed by the thoracic vertebrae, followed by the thoracolumbar spine, lumbosacral spine, cervical vertebrae, and the appendix bone is the least common. This is related to the vertebral body being heavy, easy to strain, less muscle adhesion and poor blood supply.
