What does lung cancer early imaging symptom have

summary

A neighbor always has cough recently, and it is more and more serious every day. In the end, he coughs up blood. If he wants to have imaging examination in the hospital, what are the early imaging symptoms of lung cancer? Let's talk about it.

What does lung cancer early imaging symptom have

Examination symptom 1: lobulation sign: the tumor edge is more obvious uneven arc performance, with the lobulated part of the arc as the standard: chord distance / chord length > 2 / 5 for deep lobulation. It is related to the different differentiation degree of tumor cells and the different growth rate of different parts. CT examination: the incidence rate was 80%.

Examination symptom 2. Spinous process or burr sign: a thick and blunt "pestle like" structure between lobulation and burr, with infiltration of lung cancer cells. The edge of the mass was spinous or spiculate in varying degrees, only at the interface between the mass and the lung parenchyma. Generally speaking, the burr of peripheral lung cancer is short, while the long and sparse burr of tuberculoma and chronic inflammation is long.

Pleural indentation sign: linear or triangular image between tumor and pleura, the incidence rate is about 50%, adenocarcinoma and bronchioloalveolar carcinoma are common. Formation conditions: fibrotic contraction in the direction of tumor body, no thickening and adhesion of pleura, and fibrosis in tumor body -- the fundamental driving force. Influencing factors: the distance between tumor and parietal pleura.

matters needing attention

In the lung disease, we must do early examination, early treatment, and during the treatment to do a good job in daily life and diet conditioning work, especially the patient's mood to adjust well, in many ways to promote pain relief.
