Adrenal cyst: It is mainly caused by tiny lesions in the glandular tubules in the cortical layer of the adrenal gland, such as infection, which leads to narrowing and blockage of the glandular tubules, and with the passage of time, cystic lesions will appear in CT examination. Surgical treatment can be performed under the guidance of a doctor, such as laparoscopic adrenal cystectomy and ultrasound-guided cystocentesis. If the patient has the findings of cystic occupying lesion in the right adrenal region in CT examination, it is recommended that the patient seek medical treatment in time to avoid adverse consequences.
