Lesions are a common occurrence in the liver, and the prognoses of focal liver lesions vary. The term lesion is broad and includes any wound, sore, ulcer, tumor or other tissue damage of an organ. A focal lesion in the liver refers to one area of tissue damage identified on the liver that has varying significance depending on the patient's health condition and a variety of other factors.
The world lesion is derived from the Latin term âlaesioâ which means injury. Lesion encompasses a broad meaning and hence any damage to the tissue is termed as lesion. A kidney lesion is an abnormal tissue which is damaged by some malignant growth on kidney or near it.Many times metabolic processes like trauma, ulcer caused due to electrocution, skin diseases like chicken pox or chemical burns can cause lesions to kidney.sually kidney lesions do not cause any symptoms unless they are cancerous and hence are discovered when a routine CT scan is carried out, most probably for some other organ problem. More often when a patient suffers pain from kidney stones or gallstones he has to undergo lot of scans and tests.
