Coccygeal dimple, r/o spina bifida History: Hair coming from dimple. There is a vitamin E capsule positioned on the skin overlying the coccyx. However, there is no evidence of underlying cyt or sinus tract. There is appears to be slight sacral dysraphism, although MRI is rather insensitive for such abnormalities. The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal stenosis. The spinal cord displays normal signal and morphology. The conus medullaris is positioned at the T12-L1 level, which is normal. There is no evidence of fibrofatty filum. The paravertebral soft tissues are unremarkable. The cerebellar tonsils are not low-lying. The urinary bladder appears to be distended.
1. No evidence of underlying cyt or sinus tract. 2. Suggestion of possible mild sacral spina bifida occulta, although MRI is rather insensitive for such abnormalities. 3. The conus medullaris is positioned at the T12-L1 level, which is normal. 4. No evidence of fibrofatty filum.
