What are the routine examination items for teratoma

Ovarian immature teratoma, this tumor is very malignant in our daily life. Ovarian malignant germ cells account for 5% to 15% of ovarian malignant tumors. With the continuous efforts of our medical professionals, the cure rate of this tumor is also constantly improving, from the original 10% to 20% cure rate to the current more than 95%. What are the routine examination items for teratoma?

1. MR manifestations

1. The signal intensity of the liquid fat part of the tumor shows short T1 and long T2 signals, which is the main basis for diagnosing teratoma.

2. There are mainly two structures inside the tumor: debris and wall protrusions. The wall protrusions are composed of lipid tissue, hair, teeth, and bones. Debris is often located in the lower layer of the cystic part, and liquid fat is located in the upper layer to produce layered signals. The signal intensity of debris and wall protrusions is roughly medium signal. The signal of lipid is very high on T2-weighted images, the signal of hair is lower than that of muscle tissue, and there is no signal from bones and teeth.

3. Chemical shift artifacts caused by fat can appear both inside the tumor and around the tumor. This feature can be distinguished from hemorrhagic lesions.

2. X-ray examination

X-rays of the abdomen or pelvis of the tumor can confirm the diagnosis if calcified bone tissue is found within the tumor.

3. Ultrasound and CT examination

Ultrasound examination shows that the tumor is solid or partially cystic. CT examination can understand the relationship between the retroperitoneal and sacrococcygeal teratoma and the sacrococcygeal teratoma and the surrounding tissues and organs, which can be used as a reference for estimating surgical resection.
