What are the examination methods for teratoma

Teratoma is a relatively serious germ cell disease. In many cases, people tend to confuse teratoma with other diseases. Therefore, we should do a good job of checking teratoma. Let's take a look at the following teratoma examinations. I hope it will be helpful to everyone. Let's take a look at the teratoma examinations.

What are the tests for teratoma?

(1) Lumbar puncture pressure measurement shows varying degrees of increased pressure in the vast majority of patients, and the cerebrospinal fluid protein content is generally not high.

(2) Most cranial X-rays show signs of increased intracranial pressure. If teeth, small bone fragments, or calcifications are found, this will be more helpful for qualitative diagnosis.

(3) CT scan CT scan shows irregular tumors, nodules, obvious lobes and uneven density. Usually there are solid components (high density), cysts (low density) and calcification and ossification. Multicysts are more common. Fat components can be seen in all patients, and intratumoral bleeding is rare. In a few cases, oily fluid can be seen in the ventricles that moves with changes in body position (caused by teratoma rupture into the ventricles). It is difficult to distinguish teratoma from malignant teratoma on plain CT scan, but the latter has relatively less cystic components, calcification and fat, and more solid parts.

Benign teratomas have often grown for many years and are usually large when discovered. Those in the pineal region almost all have varying degrees of supratentorial ventricular enlargement. After injection, the solid part is significantly enhanced, with extremely uneven density, and the cyst wall may be enhanced in the form of multiple ring-shaped shadows.

(4) The signals of T1 and T2 images in MRI examination are extremely mixed, but the boundaries are clear, nodular or lobed. There is no edema at the border of benign teratoma (T2 image shows clear high signal). If there is peripheral edema, it indicates that the tumor is a malignant component or a malignant teratoma. The tumor wall and solid part are significantly enhanced after injection.

(5) The tumor marker CEA may be slightly or moderately elevated. AFP is significantly elevated in patients with immature teratomas and mixed GCT containing this component.

This is all I have to say about the examinations for teratoma. I hope that the examination for teratoma must be taken seriously. In addition, when teratoma is found, it must be treated as soon as possible to avoid the teratoma from seriously affecting your health. Finally, I wish all teratoma patients a speedy recovery and avoid teratoma from harming your body.
