What is a renal hemangioma?

Renal hemangiomas are hemangiomas that invade the kidneys and are benign congenital tumors.
Hemangiomas are most likely to invade the liver, followed by the kidneys. Renal hemangiomas generally arise from the endothelium of blood vessels and lymphatic vessels, and the morphology includes capillary and cavernous hemangiomas. They are often seen unilaterally in the kidney, and in a few patients they are seen bilaterally, mostly in the submucosa of the medulla. Renal hemangiomas are most commonly seen in young and middle-aged adults, but can also be seen in children and even newborns.
Most patients with renal hemangioma have no clinical symptoms, while a few patients may present with recurrent hematuria and low back and abdominal pain. Asymptomatic patients generally do not need special treatment, daily attention to emotional stability, do not strain, appropriate exercise can be. Patients with symptoms of lumbar pain and hematuria can consider surgical excision treatment.
It is recommended that patients seek timely medical treatment and choose the appropriate treatment with the help of doctors to avoid aggravation of the condition.
