(a) T2-weighted image; sagittal section magnetic resonance imaging (MRI) of the LS spine showing features suggesting ligamentum flavum hypertrophy causing significant canal compression from posterior aspect. (b) Axial section; T2-weighted MRI, showing mass arising from posterior elements causing significant dural compression.

Magnetic resonance imaging (MRI)(Fig. 1) revealed ligamentum flavum hypertrophy and a degenerative cause for the low back pain was suspected.
Sagittal section of computed tomography scan shows a lytic lesion in L2 lamina.

Adhesiolysis was done and ligamentum flavum along with the soft tissue mass was removed (Fig. 3a). The soft tissue mass was sent for histopathological examination which showed features ofcaseous necrosis (Fig. 3b).
