The aim of this study was to reveal characteristic Doppler ultrasound and magnetic resonance imaging findings of adrenal rest tissues located in the testis.

Between August 2006 and March 2010, the patients with the diagnosis of congenital adrenal hyperplasia were retrospectively evaluated for the presence of adrenal rest within the testis. Doppler ultrasound and magnetic resonance imaging findings of the 11 patients with the diagnosis of testicular adrenal rest were documented. Follow up was made by Doppler ultrasound.

In all 11 patients with the diagnosis of adrenal rest, ultrasound revealed bilateral hypoechoic paranchymal lesions around the mediastinum testis without mass effect. Doppler ultrasound depicted slightly hypervascularity dispersing homogeneously within the lesions in all patients. All lesions were hypointense on T1-weighted MR images. The lesions were slightly hypointense relative to the testicular parenchyma on T2-weighted images. Contrast-enhanced images revealed homogeneous contrast enhancement more than normal testicular parenchyma.

Adrenal rest is relatively common among the patients with congenital adrenal hyperplasia. Doppler ultrasound and MR imaging features are characteristic for adrenal rest tissues and help to differantiate from testicular masses.

Awareness of typical Doppler US and MR imaging findings of intratesticular adrenal rest tissues in patients with congenital adrenal hyperplasia will decrease false diagnoses and invasive procedures.
