Abstract:	The aim of this study was to analyze the imaging spectrum of adrenal pseudocysts on CT. The CT images of seven patients with pathologic diagnosis of adrenal pseudocysts in our hospital were reviewed for the size, cystic part, solid part, septum, calcification, acute hematoma, and layering appearance. The presence or absence of contrast enhancement of solid parts in each lesion was also assessed if possible. Of the seven adrenal pseudocysts, there were three pure cystic, three mixed cystic and solid, and one solid lesions on CT. Two of the three cystic pseudocysts were septated with calcifications. Layering appearance was present in two mixed lesions. There were central calcifications and acute hematomas in one solid mass. In our study, there was no contrast enhancement of the solid parts of adrenal pseudocysts. The CT appearances of adrenal pseudocysts may range from cystic, mixed, to solid masses. The presence of solid parts of adrenal pseudocysts on CT mimics those of adrenal neoplasms; however, no contrast enhancement of the solid part in the lesion may help in the diagnosis of adrenal pseudocysts and their differentiation from adrenal neoplasms.
