A case report on giant C5 spinous process with partial block vertebrae at C2, C3, and C4 levels

Abstract

The spine is a complex and vital structure. Its function includes not only the structural support of the body as a whole but it also serves as a conduit for safe passage of the neural elements while allowing proper interaction with the brain. We report the case of a 7-year-old child who presented with a swelling in the posterior aspect of the neck. On lateral radiograph, there was elongated spinous process in the neck. Computed tomography examination better depicted this congenital variant and clearly showed giant spinous process of the C5 vertebrae. There was associated spina bifida at this level. Moreover, there was asymmetrical fusion of the posterior elements at C2, C3, and C4. Magnetic resonance imaging showed normal signal intensity of cervical cord. This is a very rare congenital anomaly. Very few cases have been reported previously.
