To perform a descriptive retrospective study in a tertiary care hospital of patients diagnosed with congenital adrenal lesion in a 10-year period. To identify suprarenal masses in fetal and neonatal ultrasound (US) and Magnetic Resonance (MR) to orientate their characterization and diagnosis.

Congenital lesions in suprarenal region can arise from different organs and can be benign or malignant. Fetal and neonatal US and MR can detect suprarenal masses and orientate their characterization and diagnosis. We performed a descriptive retrospective study in a tertiary care hospital of 55 patients diagnosed with congenital mass in suprarenal area antenatally (beyond 20 weeks of pregnancy) until the first 90 days after birth, from 2011 to 2021. Every patient had a fetal US at week 20 of gestation, and posteriorly US at...

Congenital masses in suprarenal area can be lesions that arise from adrenal gland and lesions from neighboring organs [1].[Fig 1] We retrospectively reviewed 55 patients with congenital suprarenal. 31 were girls and 24 were boys. Most frequent final diagnosis was hemorrhage (n=23), followed by neuroblastoma (n=17).[Fig 2] 27 cases were diagnosed antenatally on ultrasound study between week 20 and week 40, while 28 cases were identified after birth on postnatal ultrasound studies between day 0 and 90 days after birth. Fetal MR complemented US in...

The adrenal gland can be visualized at obstetric US beyond 13 weeks of gestation, being large and globular. In neonates, adrenal gland on US shows differentiation between cortical and medulla, smooth undulations and characteristic shape of two legs [2]. [Fig 9] With child growing, corticomedullary differentiation diminishes by 6 months of age. Beyond this age, the visualization of adrenal glands on US may be difficult. Recognizing the normal shape of adrenal glands in neonates is important because sometimes a lesion does not appear as focal,...
