Left kidney fine low density foci should refer to the imaging examination of kidney, left kidney fine low density foci may be renal cysts, renal misshapen tumor, renal clear cell carcinoma and other diseases, which can be treated by puncture sclerotherapy, surgical treatment and drug treatment.
Kidney cysts: If kidney cysts are caused by environment, heredity and other reasons which lead to imaging suggesting fine low density foci in the left kidney, simple renal cysts with cysts less than 2cm, no clinical symptoms, not affecting renal function, and less chance of malignant changes usually need no treatment.
If the cyst is larger than 5cm and accompanied by flank swelling and pain, bleeding, fever, renal hypertension, etc., renal cyst puncture sclerotherapy can be used; if the cyst is larger than 10cm, suspected cancer, recurrence of cysts after puncture can be surgical treatment under the guidance of the doctor.
2. Renal staggered tumor: If the renal staggered tumor is caused by the fat, smooth muscle and abnormal blood vessels of the kidney due to heredity, development and other reasons, it may cause small low-density foci in the left kidney. If the renal malformation tumor is associated with tuberous sclerosis, patients can take everolimus as prescribed by the doctor, and if the volume gradually increases, surgery is feasible. If the renal stenoma ruptures or bleeds, patients should consult the doctor in time.
3. Renal clear cell carcinoma: renal imaging suggests that small low-density foci in the left kidney with hematuria, lumbago, hypertension and other manifestations may be renal clear cell carcinoma, which can be treated with surgery according to doctor’s suggestion.
If the imaging test suggests small hypodense foci in the left kidney, other related examinations should be completed under the doctor’s suggestion to clarify the cause of the disease and treat the cause.
