Abstract:
Caudal regression syndrome (CRS) involves improper and incomplete development of distal spinal segments. Sacral rib is an unusual entity, where an accessory rib arises from the sacral vertebral segments. Very few cases have been described in the English literature. We present the case of a 3-year-old girl presenting with urinary and bowel incontinence and difficulties in walking with left-sided sacral rib, terminal cord syrinx, and caudal regression syndrome, involving sacrococcygeal segments, diagnosed on MRI. The association is not well illustrated in previous reports.

Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form the...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
