Objective To summary the image signs of primary solitary fibrous tumor of the adrenal gland, raise awareness of the image signs of the disease, and reduce misdiagnosis. Methods Reported the clinical characteristic and radiology imaging of 1 cases which was diagnosed as primary solitary fibrous tumor of the adrenal gland, and reviewed the relative literature. Results The patient is female and 30 years old. The ultrasonography showed that the tumor was a hypoechoic lesion with well-defined borders, an integrated membrane and abundant blood flow signals . On CT contrast scan, the solid portion of tumor is obviously enhanced, whereas the low density areas within it does not occur enhancement. Conclusion There were features in the performance of CT of primary solitary fibrous tumor of the adrenal gland. Combined CT scan with Clinical and support fiber endoscopy can Make more accurate diagnosis.
