Abstract:
Objective To probe the imaging diagnostic characteristics of skull base-type pituitary adenoma (SBPA). Methods CT, conventional MRI, dynamic MRI, and pathological data of 16 patients with SBPA were analyzed. The manifestations of both CT and conventional MRI, the dynamic time-signal curve, time of peak enhancement, and average enhancement rate were compared between SBPA in the 16 patients and chordoma of the skull base (CSB) in another 9 patients. Results The CT appearances of both tumors were quite similar, offering no differential value. Both tumors were slightly hypointense on T 1 weighted images, but SBPA was mildly hyperintense and CSB was markedly hyperintense on T 2 weighted images. The T 2 weighted signal intensity between both tumors differed significantly (P5 min, (40?5) /min for CSB, respectively (P
