[|AI|]  Thank you for contacting Chat Doctor. Your father had headache and seizures (twisting of left hand). This was because of the lesion (problem) identified on the MRI and CT scan on the right side (right side of brain controls the left hand). The possible causes of ring lesion in brain include infections (such as tubercolosis-TB, tapeworm infection- neurocysticercosis) and tumors (cancer, etc.). Proper treatment depends on identifying the exact cause. This can be done by a small surgery (biopsy of the lesion). In surgery, doctors would remove the ring lesion (in part or total) and send it to pathology lab. The lab will get back with the report in a few days. In addition, anti-epileptic Chat Doctor. Best wishes,
