Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. There is a disc bulge with anterior thecal sac and little part of the spinal cord is coming out of that sac. It s a common finding and happens in all indentation cases. You don t have to worry so much about that. Since it is progressive, it can get worse. I don t know whether neurosurgeon has told you to fix this up with surgery or not if he says then better to get it fixed at the earliest rather than delaying. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Archana
