Hi. I am a 49 y/o female. Several weeks ago I noticed a soft movable lump in my right groin area. I have a history of a right inguinal hernia which was repaired appx. 27 years ago. My physician thought it not to be a recurring hernia but rather a enlarged lymph node and placed me on antibiotics and ordered a Ultrasound of the right groin. The ultrasound suggested it to be a complex cyst. I was then referred to a surgeon who also thought it to be a enlarged lymph node and ordered a CT of the abdomen and Pelvis w and w/o contrast. The CT describes the area as a ovoid fluid collection and fatty density w/o significant enhancement which may represent a right inguinal hernia with free fluid. It further states the fatty density is of unknown etiology but may represent minimal herniated fat or less likely a lymph node. It continues to note that there is no evidence for significant lymphadenapathy within the pelvis or abdomen. The surgeon did his own in office F/U ultrasound and he states it is a "lipoma of the cord, therefore represents a recurring cyst" and is recommending surgery. Can you tell me what test is more accurate and what you think this lump might be.
