Objective: To explore the imaging features of congenital adrenal cortex hyperplasia (CAH).
Methods: A total of 45 patients clinically confirmed as CAH were retrospectively analyzed to investigate the imaging features and strengthening way of the multi-detector-row Computed tomography.
Results: The imaging features of all the cases presented as following: 25 with bilateral adrenal hyperplasia, 6 with unilateral adrenal hyperplasia, 6 with adrenal nodular hyperplasia, 2 with adrenal hyperplasia and unilateral solid cystic lesion, 2 with adrenal hyperplasia and double side real cystic lesion, 1 with adrenal hyperplasia and unilateral cystic changes and 3 with normal adrenal. The unilateral or bilateral hyperplasia adrenal could be homogeneously enhanced, while the enhanced performance of other cases was inequitable.
Conclusions: The adrenal imaging features of CAH by multi-detector-row CT are variable, with the bilateral adrenal hyperplasia as the main form, which could be restored to normal morphology after hormone replacement therapy.No regression of the tumor size is observed in cases with adrenal mass. CT scanning combined with clinical manifestation and biochemical examination could facilitate the diagnosis of CAH.
