Presentation
Progressive right quadriceps weakness. Right leg pain.
Patient Data
Age: 60 years
Gender: Female
From the case:
Foraminal and subarticular lumbar disc prolapse

Right foraminal and subarticular disc prolapse at L3/L4. This effaces the fat around the L3 nerve root as it exits the neural foramen at L3-4.
L4-5 small central bulge. The canal and foramina are preserved.
L1 conus. Normal cauda equina.

Case Discussion
Small (easily missable) focal foraminal and subarticular disc prolapse.
The MRI study includes an axial T2 3D volume sequence, offering a higher resolution sequence to enable more refined assessment of the nerve roots, which is particularly useful in this case where the disc pathology is small, subtle and in a confined anatomical space.
