Urinary incontinence and lower limb weakness

Patient Data

Age: 9 years old
Gender: Female

LSS Xray (Frontal and lateral views)

There is absent lower sacrum and coccyx with hypoplasia of S2

No hip dislocations or subluxation seen

Some bowel loops appear distended with fecal loading



The MRI confirm the X ray findings

There is abrupt truncation of the conus medullaris at the level of T12/L1 (normally should end at L1/L2), no tethered cord seen

No spinal masses seen or synrinx in the visualised cords, or meningiocoele / meningiomyelocoele, and no hydrocephalus (not shown here)

No other associated vertebral anomalies in the rest of her spine (not shown)

In conclusion, findings are compatible with type I caudal regression syndrome
