This is what I found about myelomalacia ~ I found it on this site, but it originally came from Wikipedia. It explains it alot better than I can and it also explains EXTREME cases too, so don't be alarmed about it. If you have any questions, please let me know. But it CAN cause problems with the bowel and bladder. So please check with your doctor or see a specialist as soon as possible.
MRI image shows spinal bleeding (myelomalacia).Myelomalacia is a pathologicalterm referring the softening of the spinal cord. Hemorrhagic infarction (bleeding) of the spinal cord that can occur as a sequel to acute injury, such as that caused by intervertebral disc extrusion (being forced or pressed out) is the cause of myelomalacia.  The disorder causes flaccid paraplegia (impairment of motor function in lower extremities), total areflexia (below normal or absence of reflexes) of the pelvic limbs and ****, loss of deep pain perception caudal (in the coccyx) to the site of spinal cord injury, muscular atrophy (wasting away of muscle tissue), depressed mental state, and respiratory difficulty due to intercostal (muscles that run between the ribs) and diaphragmatic paralysis.
