Unusual degenerated disc migration along sacral nerve root into neural foramina up to pelvic cavity

A 39-year-old female patient who had mild low back pain of 1-year duration, presented with sudden severe worsening of back pain since 1 week, associated with radiating pain along the left lateral thigh, leg, as well as along the dorsum of foot.
