Introduction to methods for examining hamartoma

Hamartoma is a benign tumor disease. The main high-risk population is women over 40 years old. Renal hamartoma is a common type. Since the symptoms of renal hamartoma are relatively obvious, as long as you have a certain amount of common sense, you can achieve timely discovery, examination and treatment. So how to check for hamartoma? Regarding this issue, the following is an introduction to the methods of checking hamartoma.

The standard medical name for renal hamartoma is renal angiomyolipoma. As the name suggests, its main components are blood vessels, smooth muscle and fat. Hamartoma can occur not only in the kidneys, but also in the brain, eyes, heart, lungs, bones and other parts. In the past, renal hamartoma was considered a rare disease. In recent years, with the development of medical imaging and people's attention to health examinations, its detection rate has gradually increased. Renal hamartoma can be clearly diagnosed based on symptoms and signs combined with imaging examinations.

Renal Hamartoma Examination Methods

1. Laboratory examination

Urine examination may show occult blood. Bilateral renal hamartoma may present with hypertension and renal insufficiency, and laboratory tests may show abnormalities in blood creatinine and urea nitrogen.

2. Imaging examination

(1) Ultrasound examination is quite characteristic. The fat and blood vessels in the tumor show evenly distributed dense high-echo areas, while the muscle and hemorrhage parts show low-echo areas.

(2) X-ray abdominal films show unclear renal contours, disappearance of the psoas muscle shadow, and calcification in the renal area. Urinary tract angiography shows that the mass compresses the renal pelvis and calyces, causing them to deform, lengthen, or shorten, but without any invasion.

(3) CT is the main method for diagnosing renal hamartoma. It is a mass with uneven density and high fat content, and the CT value is -40 to -90 Hu.

(4) MRI In recent years, MRI examination has also played an increasingly important role in the diagnosis of renal hamartoma.
