Kopylova Symptom

Kopylov's sign is a medical term that describes certain changes in the X-ray image of the lungs associated with heart disease. This symptom was discovered and described by Soviet radiologist Alexei Kopylov in 1962.

Kopylov The symptom appears as a shadow on an x-ray of the lungs, which resembles the letter “U” or an inverted letter “V”. This shadow is formed as a result of the accumulation of fluid in the pleural cavity (the space between the lungs and the chest wall).

With heart disease, especially heart failure, fluid accumulates in the pleural cavities and can cause the Kopylov Symptom on an x-ray. This may be a sign that the heart is unable to pump blood effectively throughout the body and that additional medical attention is needed.

It is important to note that the Kopylov Symptom can be either a sign of a serious heart disease or a consequence of other conditions, such as pneumonia or pleurisy. Therefore, if you suspect Kopylov Symptom, you should consult a doctor for further examination and treatment.

Kopylov's symptom is the loss of the transverse sinuses in the cranial part of the second sagittal plane, provided that all the dentate gyri and the anterior gyrus of the brain are preserved. In normal cases, the sinuses are traced to the thalamus, cerebrum and anterior horn of the quadrigeminum, although in most cases they disappear towards the anterior end of the cerebrum.

The term “Koply’s symptom” was established thanks to the French neurosurgeon O. Kopla - he managed to detect this symptom in cases of cerebral strokes. This is a rather late symptom, observed only in 20-25% of patients (at the very beginning of a cerebral stroke). The point is that usually brain tissue is lost sequentially from bottom to top, starting, as a rule, from diffuse areas of the cortex, then paraventricular and subcortical structures (medial geniculate body, posterior part of the internal capsule and subthalamus, bases of the cerebral ventricles). Such areas do not have hemorrhages (hemorrhages are usually observed at intersections, i.e., openings not covered by the cranial bladder, which continue through the grooves -
