hello saw your query on HCM... your ultrasound test report states the presence of cortical cyst in upper pole of right kidney which is less than 3 cm in size in diameter. presence of cortical cysts are usually seen as an incidental findings in many patients and i do mention this findings on daily basis and should not be worried as such. however a point of caution should be given when there are signs of complexities within the cyst if any which we call as complex cyst. this point has not been mentioned by you whether it is a simple cyst or complex cyst. it should have been stated by your radiologist. if it read a simple cortical cyst then according to me there is no reason to worry. simple cortical cysts usually do not causes any pain and hence do not explain your problem of lower Abdominal pain as such. get yourself clinically evaluated by your local physician for diagnosing proper cause of the pain. thank you and i hope your query is answered... if you have any more query you can contact us..
