title: Nonspecific perichondritis of the lumbar spine.
abstract: A teenage girl with soft tissue inflammation involving the L2-S1 region of the lumbar region is reported. Magnetic resonance (MR) imaging revealed high-signal lesions on T2-weighted images in association with contrast enhancement. Histology revealed nonspecific perichondritis with mononuclear inflammatory infiltration of the perichondrium and connective tissue. Six months after treatment, MR imaging was normal. No similar case of perichondritis with involvement of the lumbar region could be found in the current literature.
