Massive L4/L5 extrusion completely compressing the cauda equina in the thecal sac.

T12/L1 conus.

Case Discussion

As far as disc extrusions go, this is about as big as it gets.   The cauda equina is completely compressed in the by the disc.

Amazingly this was a young patient having an elective MR lumbar spine from the family doctor, not in Accident and Emergency with red flag signs.

Radiological appearances and symptoms can vary hugely,  Not infrequently I report lumbar spine studies where the significant radiological findings are on the contralateral side to the patient's symptoms.
