Abstract
Tuberous sclerosis complex (TSC) is a multiple system neurocutaneous syndrome with a genetic disorder caused by different mutations in TSC1 or TSC2. Usually, TSC causes tumors in the heart, brain, kidneys, eyes, and lungs. However, tumors can also develop in any other organs. The prenatal diagnosis of TCS is based on the identification of fetal cardiac tumors by ultrasound and brain subependymal nodules, usually identified by fetal magnetic resonance imaging (MRI). We present two case reports of the prenatal diagnosis of TCS using both ultrasound and MRI, which were confirmed by clinical and radiological methods in the postnatal period accordingly.

Abstract
UNLABELLED Renal involvement is very common in tuberous sclerosis complex (TSC) and is characterized by the development of angiomyolipoma and cysts. The aims of the present study were to assess kidney function and clinical features of renal involvement in TSC, including kidney function and blood pressure (BP) levels in children, adolescents and young adults. Non-selected patients with a definite diagnosis of TSC attending the paediatric neurology outpatient department of a tertiary hospital were included in a cross-sectional study. All participants had a renal imaging study within 6 months of ambulatory blood pressure (BP) and glomerular filtration rate (GFR) assessment. Data on demographics, history, genotype, kidney function at diagnosis and last imaging were collected. Twenty patients were enrolled in this study with a median age of 15 years (IQR range 9 to 18). About 23.5% of the participants had ambulatory hypertension. Systolic BP levels correlated significantly with GFRDTPA values despite the absence of hyperfiltration. Patients that developed hypertension and possibly those with angiomyolipoma or cysts had higher GFR levels in childhood and adolescence. All the patients with ambulatory hypertension had angiomyolipoma or cysts on renal imaging studies. CONCLUSIONS Hypertension may present with increased frequency in young patients with kidney disease associated with TSC. Routine ambulatory BP measurement should be part of the annual clinical assessment in patients with TSC. WHAT IS KNOWN • Nearly half of the patients with TSC have a premature decline in their renal function in their fifth decade of life. • Hypertension and hyperfiltration have been proposed as modifiable factors of progression of renal decline in patients with TSC-related renal disease. WHAT IS NEW • Hypertension is prevalent in youth with tuberous sclerosis complex. • SBP levels have a positive relation with GFR levels within the normal range of GFRDTPA values.
