Hi, There are many causes of such cysts like so you need more imaging. I recommend MRI, CT, X-ray to begin with your specialist. CT guided radiofrequency ablation has emerged as a less invasive alternative to surgical resection. In this technique, which can be performed under conscious sedation, a RF probe is introduced into the mass through a cannulated needle under CT guidance and heat is applied locally to destroy the cells. Since the procedure was first introduced for the treatment.it has been shown in numerous studies to be less invasive and expensive, to result in less bone destruction and to have equivalent safety and efficacy to surgical techniques, treatment with incision less surgery utilizing an MRI to guide high-intensity ultrasound waves to destroy a benign bone tumor in the skull has been demonstrated lately you may ask your specialist about it if you really need to remove it. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Ahmed Aly Hassan
