What tests are needed to diagnose pulmonary hamartoma

What tests should be done to confirm pulmonary hamartoma? No one wants to get sick, but in life, it is inevitable that some diseases will bother you. But don't worry, after all, medical technology is very mature now. Timely discovery, timely examination and diagnosis, generally no big problem in treatment, so what tests should be done to confirm pulmonary hamartoma?

The origin and cause of pulmonary hamartomas are not yet clear. The more easily accepted hypothesis is that hamartomas are a piece of bronchial tissue that inverts and falls off during embryonic development and is surrounded by normal lung tissue. This part of the tissue grows slowly or may not grow for a certain period of time, and then gradually develops to form a tumor. The fact that most hamartomas develop after the age of 40 supports this hypothesis.

1. X-ray examination

X-rays show uniform and dense shadows, or uneven shadows, and calcification. The calcification shadow presents 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 SPNs. The discovery of obvious popcorn-like calcification facilitates dynamic observation of lesions. Fibrous hamartomas have no calcification, and fat density is difficult to judge on traditional X-rays, and are often misdiagnosed.

2. CT examination

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

② Most lesions are smaller than 5 cm.

③The lumps are mostly soft tissue density lumps, which often contain fat density areas, which are 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.
