A 12-year-old boy who presented with hypertensive encephalopathy was referred to endocrinology because of hyperpigmentation. On examination, he had normal stature for age (height: 138 cm, height z-score: –1.25) but advanced bone age (18 years) suggesting severe compromise of final adult height. Tanner’s sexual maturity rating was P4 and G4 (stretched phallic length: 9 cm). The right and left testes measured 5 mL and 8 mL [Figure 1], respectively. Both testes were nodular with variable consistency (hard in the upper part and soft in the lower part).

His sitting blood pressure in the right arm was 160/100 mmHg. Serum potassium was 2.67 mEq/L. Serum total testosterone was 229.77 ng/dL but the luteinizing hormone was suppressed (0.03 mIU/mL). Serum 8:00 am cortisol level was low (0.39 μg/dL) with slightly elevated serum 17α-hydroxyprogesterone (239.3 ng/dL) but markedly elevated serum corticosterone (>5000 ng/ dL; normal range: 18–1970 ng/dL) and serum 11-deoxycortisol (>2000 ng/dL; normal range: 20–158 ng/dL) levels. The patient was diagnosed to have 11β-hydroxylase deficiency. Ultrasound scrotum revealed bilateral testicular adrenal rest tumors (TARTs) [Figure 1]. The patient was started on glucocorticoid replacement.

The prevalence of TART in pediatric CAH patients is around 18–24% whereas the rates up to 94% have been reported in adults.[1,2] TARTs are always benign but may cause infertility; hence, should be detected and treated early.[2] Screening for TART with testicular ultrasound should begin in adolescence and repeated every 1–2 years in asymptomatic but more frequently in symptomatic patients.[3] Optimization of glucocorticoid replacement helps to shrink early TART.[3]
