What are the routine examinations for hamartoma

What are the routine examinations for hamartoma? Because hamartoma is difficult to judge and the clinical symptoms are not very obvious, it is necessary to conduct timely examination and diagnosis for such a disease. So what are the routine examinations for hamartoma? Let's learn about this issue through the article below.

What tests should be done if hamartoma is suspected:

1. X-ray examination

X-rays show uniform and dense shadows, or uneven shadows, and calcification. The calcification shows a popcorn-like pattern, and the density of the peripheral part is relatively low, which may be adipose tissue. The popcorn sign is a characteristic manifestation of pulmonary hamartoma, but it is rare and not unique to pulmonary hamartoma. Chest X-rays can detect the presence, size, and presence of satellite lesions of SPN. Obvious popcorn-like calcification is found, which facilitates dynamic observation of lesions. Fibrous hamartomas have no calcification, and fat density is difficult to judge on traditional X-rays and is often misdiagnosed.

2. CT examination

① The edge of the lesion is smooth, mostly round or quasi-round, without burr sign, but may have lobulation sign.

②The lesions are mostly smaller than 5 cm.

③The masses are mostly soft tissue density masses, which often contain fat density areas, which are their typical CT manifestations.

④ Calcification in the lesion is spotty or patchy, and the typical calcification is popcorn-like.

⑤ Most of the lumps are located in the lungs, a few are close to the hilum of the lung, and some are located in the tracheal cavity. There are no enlarged lymph nodes in the hilum of the lung and the mediastinum.

⑥ After enhancement, the mass showed no enhancement or only slight enhancement.

3. 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 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 hamartoma.

What tests should be done if a hamartoma is suspected? Renal angiomyolipoma is a benign tumor composed of blood vessels without normal elastic tissue, smooth muscle and mature adipose tissue. Small ones are often asymptomatic, while large ones are prone to bleeding, necrosis and cystic changes. Those with less fat content are easily misdiagnosed as renal cancer. Regular health checks can detect tumors early. Women with acute abdominal pain accompanied by intra-abdominal masses or internal bleeding symptoms should consider the possibility of this disease.
