For the imaging manifestations of pituitary tumors, it is generally recommended that patients undergo a CT scan of the sellar region. CT scanning of the sellar region is one of the most effective methods for diagnosing pituitary tumors. Clinically, it is generally recommended that patients undergo enhanced CT scans and thin-layer scanning, with coronal and sagittal scans of the sellar region, thereby effectively increasing the detection rate of pituitary tumors. Typically, it appears as a distinct low density in the saddle area, most often presenting as isodense or hypodense, and less commonly as hyperdense. Generally, it presents with the height of the pituitary exceeding 7mm and with the diaphragma sellae showing significant fullness or asymmetric bulging, often suggesting a higher likelihood of a pituitary tumor. Additionally, large pituitary adenomas generally appear as high-density shadows, often occupying the entire saddle area.
