Abstract
OBJECTIVE We describe the clinical and genetic characteristics of fetuses and infants diagnosed with tuberous sclerosis complex (TSC) in our centre, prenatally or neonatally, for a better understanding of the benefits of early screening. METHODS In this retrospective study, we analysed the data on one fetus and nine infants with a definitive TSC diagnosis by genetic criteria (five patients carrying TSC1 variants and 5 patients carrying TSC2 variants). We explored the differences between phenotypes of patients carrying TSC1 and TSC2 pathogenic variants. RESULTS The most common initial presenting features of TSC were cardiac rhabdomyomas (CRs) that were observed in nine out of ten patients. The most common postnatal features, besides CR, were presented with subependymal nodules-in five patients, and hypomelanotic macules-in four patients. In total, 10 variants causing TSC were detected in this study, including 5 novel variants. We demonstrated that patients with TSC2 variants had earlier onset and more severe clinical manifestations compared with patients carrying TSC1 variants. CONCLUSION Early diagnosis of TSC improves genetic counselling and perinatal management.

Goergen SK, Fahey MC. Prenatal MR Imaging Phenotype of Fetuses with Tuberous Sclerosis: An Institutional Case Series and Literature Review. AJNR Am J Neuroradiol 2022; 43:633-638. [PMID: 35332020 PMCID: PMC8993194 DOI: 10.3174/ajnr.a7455] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2021] [Accepted: 01/10/2022] [Indexed: 11/07/2022]
Abstract
BACKGROUND AND PURPOSE Most patients with tuberous sclerosis complex (TSC) do not receive prenatal diagnosis. Our aim was to describe MR imaging findings to determine the following: 1. Whether normal fetal MR imaging is more common in fetuses imaged at ≤24 weeks' gestation compared with >24 weeks 2. The frequency of cardiac rhabdomyoma 3. The range of MR imaging phenotypes in fetal tuberous sclerosis complex. MATERIALS AND METHODS Our institutional fetal MR imaging data base was searched between January 1, 2011 and June 30, 2021, for cases of TSC confirmed either by genetic testing, postnatal imaging, postmortem examination, or composite prenatal imaging findings and family history. A MEDLINE search was performed on June 8, 2021. RESULTS Forty-seven published cases and 4 of our own cases were identified. Normal findings on fetal MR imaging were seen at a lower gestational age (mean, 24.7 [SD, 4.5 ] weeks) than abnormal findings on MR imaging (mean, 30.0 [SD, 5.3] weeks) (P = .008). Nine of 42 patients with abnormal MR imaging findings were ≤24 weeks' gestation. Subependymal nodules were present in 26/45 cases (57.8%), and cortical/subcortical lesions, in 17/46 (37.0%). A foramen of Monro nodule was present in 15 cases; in 2/7 cases in which this was unilateral, it was the only abnormal cerebral finding. Cardiac rhabdomyoma was absent in 3/48 cases at the time of fetal MR imaging but was discovered later. Megalencephaly or hemimegalencephaly was observed in 3 cases. CONCLUSIONS Fetuses with abnormal cranial MR imaging findings were older than those with negative findings. Fetal hemimegalencephaly and megalencephaly should prompt fetal echocardiography. Cardiac rhabdomyoma was not always present at the time of fetal MR imaging.

Abstract
Tuberous sclerosis complex (TSC) is a complex disease with many different clinical manifestations. Despite the common opinion that TSC is a rare condition, with a mean incidence of 1/6000 live births and a prevalence of 1/20,000, it is increasingly evident that in reality this is not true. Its clinical sequelae span a range of multiple organ systems, in particular the central nervous system, kidneys, skin and lungs. The management of TSC patients is heavily burdensome in terms of time and healthcare costs both for the families and for the healthcare system. Management options include conservative approaches, surgery, pharmacotherapy with mammalian target of rapamycin inhibitors and recently proposed options such as therapy with anti-EGFR antibody and ultrasound-guided percutaneous microwaves. So far, however, no systematically accepted strategy has been found that is both clinically and economically efficient. Thus, decisions are tailored to patients' characteristics, resource availability and clinical and technical expertise of each single center. This paper reviews the pathophysiology and the clinical (diagnostic-therapeutic) management of TSC.

Abstract
OBJECTIVES To determine the prevalence of specific cerebral lesions of tuberous sclerosis complex (TSC) and neurological outcome in cases diagnosed prenatally with cardiac rhabdomyomas. METHODS We reviewed all fetuses diagnosed prenatally with cardiac rhabdomyomas which had undergone detailed ultrasound evaluation and cerebral magnetic resonance imaging (MRI) and which were recorded in the database of a single institution covering the period January 1992 to December 2005. RESULTS Fifty-one fetuses were included in the study. MRI was performed at a mean +/- SD gestational age of 30 +/- 3 gestational weeks and showed specific lesions of TSC in 49% of cases. Termination of pregnancy was chosen by the parents in 26 cases. Neurological development was studied in 20 cases, follow-up lasting 4.8 +/- 2.9 years. Neurodevelopmental events occurred during the follow-up period in 45% of cases. Neurological complications occurred in 67% of patients who had cerebral lesions at MRI and in 33% of patients with normal MRI results. There was no significant difference between the two groups of patients (P = 0.2). CONCLUSION In fetuses with cardiac rhabdomyomas detailed ultrasound examination and third-trimester cerebral MRI are able to diagnose most TSC cerebral lesions, but fail to determine neurological outcome.

Abstract
Tuberous sclerosis complex (TSC) is an autosomal-dominant neurocutaneous disorder with multi-organ involvement. The diagnosis is suspected at fetal ultrasound on the discovery of multiple cardiac rhabdomyomas (CRs). They typically develop in utero and undergo spontaneous regression during the first years of live. With developing neuroradiological methods more light is shed on antenatal cerebral lesions like cortical tubers or giant cell astrocytomas. Unfortunately these do not regress, but instead are in principle progressive in size and number, correlated with epilepsy, mental retardation and behavioral problems. It is unknown whether fetal cerebral lesions, are always correlated with a poor neurological outcome or a progressive course of disease. This makes prenatal counseling extremely difficult. We report one case of de novo TSC with first detection of cortical tubers on fetal ultrasound, later developing multiple CRs. The pregnancy was continued and the child is developing well during 16 months of follow-up. Minor motor seizures from the 10th month onwards are successfully treated with Valproate. The published cases with antenatal diagnosis of TSC are revised, trying to get more insight into the postnatal course of prenatally diagnosed TSC. This is crucial, either when termination of pregnancy (TOP) is considered, but even more for proper postnatal care and follow-up.

Abstract
BACKGROUND Tuberous sclerosis complex (TSC) is an autosomal dominant phakomatosis associated with intracardiac rhabdomyomas. OBJECTIVE The aim of our study was to examine the value of cerebral MRI in diagnosing TSC in fetuses with intracardiac rhabdomyomas, applying the TSC Consensus Conference (TSCCC) criteria. MATERIALS AND METHODS In a prospective manner six consecutive fetuses with cardiac rhabdomyomas (21-34 weeks' gestation) underwent cerebral MRI. The MRI results were correlated with clinical follow-up at 10-34 months after birth, histology, and genetic data. RESULTS In five of the six fetuses the diagnosis of TSC was established. In two of five fetuses MRI demonstrated cerebral manifestations of TSC that correlated well with severe epilepsy manifesting during the follow-up period. In another two of five fetuses MRI as well as clinical follow-up were normal. One of five pregnancies was terminated and histology demonstrated microscopically small subependymal nodules not demonstrated by MRI. CONCLUSION The results of our study agree with the available literature that fetal MRI is sufficient for the detection of cerebral lesions in TSC and should be better promoted. The TSCCC criteria can also be applied to fetal MRI.

Abstract
The phakomatoses are a diverse set of disorders related principally by a similar tendency to produce patchy manifestations that affect the nervous system and various other tissues. All of the disorders involve the occurrence of benign neoplasms or hamartomatous growths, and all involve the action of a distinct gene that functions as a tumor suppressor. At present, none of the phakomatoses is amenable to effective medical treatment, so management is limited to surveillance and treatment of progressive lesions. The radiologist plays a key role in this management, participating in diagnosis and follow-up of affected patients.

Abstract
PURPOSE Tuberous sclerosis is an autosomal dominant neurocutaneous syndrome affecting multiple organ systems and demonstrating highly variable clinical manifestations. Mutations in 2 tumor suppressor genes, TSC1 and TSC2, are linked to the evolution of the hamartomatous lesions. We describe the incidence and epidemiology, variable clinical manifestations and their relationships to renal pathology, and the management of morbid sequelae. MATERIALS AND METHODS Using the search term tuberous sclerosis, we performed a MEDLINE search of the literature identifying 3,196 articles and selected those from urological, surgical, oncological, genetic and pediatric journals. Special focus was placed on the incidence and management of renal lesions and on different clinical manifestations and how they relate to renal tumors. RESULTS Due to improved identification of the variable phenotypic expression, the reported incidence has increased. TSC1 and TSC2 mutations are related to various phenotypic manifestations and risks of malignancy, such as an increased incidence of the TSC2 mutation in patients with renal cell carcinoma. Renal sparing surgery and selective embolization techniques have mitigated the morbidity of the lesions. CONCLUSIONS We now have a better understanding of the variability at the genotypic and phenotypic levels of the disease. We recommend that patients with tuberous sclerosis complex be evaluated by a multidisciplinary group of clinicians, including urologists, dermatologists, neurologists, pediatricians and geneticists. Close attention to these manifestations is necessary to ensure appropriate treatment of the sequelae of the tuberous sclerosis complex.
