Objective: The aim of this study was to evaluate the perinatal outcomes and postnatal follow-up of prenatally diagnosed suprarenal masses (SRMs) evaluated by magnetic resonance imaging (MRI). Methods: Thirteen fetuses with SRMs detected during routine prenatal ultrasound screening were evaluated by MRI between February 2007 and May 2015. The prenatal characteristics of the masses, complications of the pregnancies, and related malformations were collected as the postnatal clinical, radiological, and pathological data. Results: The median gestational age at MRI was 30 weeks (18-41), and birth weight was 3285 (1700-3750) g. The mean follow-up period was 6 years (1.3-10). We observed 69.2% of the masses, which were predominantly cystic (69.2%), located on the left side. Associated malformations were found in 23% of the fetuses, with congenital heart defects being more prevalent. During the pregnancy, 15.4% of the fetuses had involution of the SRM, and one fetus had surgical treatment and different ultrasound and MRI diagnoses. Of the 69.2% of the cases, spontaneous resolution occurred in 30.7% during the first year of life and 38.4% the masses presented without modifications or signs of regression since the neonatal period. Conclusions: Prenatal SRMs were associated with congenital heart defects. Spontaneous regression and absence of modifications in the masses were commonly observed in the long-term follow-up of the SRMs.
