[|Human|] Hi,My 31 yo son went to the ED today for crampy pain in his left flank, blood in his stool (he says only with straining); they checked labs and urine which were fine and did a CT scan which showed a hypodense area in upper pole of left kidney with some extension into perinephric fat; differential dx was infectious etiology vs ischemia.  Can you comment?
[|AI|]  HelloThanks for query. Your 31 years old son had a pain in left flank and his CT scan of abdomen has revealed Hypo dense mass in upper pole of left kidney. The hypo dense lesion detected needs further evaluation to rule out its nature whether benign or malignant or infective . Please consult qualified Urologist for clinical examination and get following basic tests done to confirm the diagnosis.1) C. T Scan with me. V contrast 2) C. T angiography 3) M.R.I Further treatment will depend upon result of these tests and final diagnosis.diagnosis.  Chat Doctor.
