Abstract
Cardiac tumours can occur in association with genetic syndromes. Rhabdomyomas have been reported in association with tuberous sclerosis, myxomas with Carney's complex, cardiac fibromas with Gorlin syndrome, and paragangliomas with multiple endocrine neoplasm syndrome. The presentation and prognosis of cardiac tumours associated with genetic syndromes differ compared with sporadic cases. Knowledge about the associated syndromes' genetic features and extracardiac manifestations is essential for the diagnosis, prognosis, and management of cardiac neoplasms. Moreover, identifying genetic mutations in benign and malignant cardiac tumours is needed to personalise management and improve treatment outcomes. Thus, this review discusses the genetic abnormalities associated with cardiac tumours, the current genetic screening recommendations, and the effect of those genetic mutations on the outcomes.

Regression of Cardiac Rhabdomyomas Producing a Severe Aortic Stenosis: Case Report and Discussion of the Literature. Diagnostics (Basel) 2024; 14:470. [PMID: 38472942 DOI: 10.3390/diagnostics14050470] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 01/23/2024] [Accepted: 02/16/2024] [Indexed: 03/14/2024] Open
Abstract
We describe a case of a voluminous rhabdomyoma (R) detected by fetal echocardiography at 32 weeks' gestation (w.g.) obstructing the left ventricular inflow and aortic outflow tract, with a moderate aortic gradient at birth, not needing immediate surgery. At follow-up, the mass progressively regressed, leaving the aortic valve partly damaged, with a gradient that increased to a maximum of 100 mmHg at 9 years. The girl was then operated on successfully by a plasty of the aortic valve. The literature regarding R is discussed.

Abstract
Tuberous sclerosis complex (TSC) is an autosomal dominant genetic disease characterized by hamartomatous tumors involving multiple organs such as the brain, skin, heart, lung and kidney. TSC is caused by inactivating mutations in TSC1/TSC2, which encodes hamartin and tuberin, respectively, and forms a complex that regulates mechanistic target of rapamycin complex 1 (mTORC1), resulting in cell overgrowth and oncogenesis. Since a leading cause of morbidity and mortality in TSC relates to chronic kidney disease and the ability to preserve renal function, this review describes the important pathologic findings in TSC-associated renal neoplasms and their correlating sporadic counterparts. The most common renal tumor in TSC patients are AMLs, followed by a heterogeneous spectrum of renal epithelial tumors, which may provide clues to establishing a diagnosis of TSC.

[PMID: 38062408 PMCID: PMC10701948 DOI: 10.1186/s12872-023-03639-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Accepted: 11/29/2023] [Indexed: 12/18/2023] Open
Abstract
BACKGROUND Despite its rare incidence of 1/40,000, fetal cardiac rhabdomyoma (CR) represents the prevailing type of benign cardiac fetal tumors, which commonly affects the ventricles. Fetal CRs rarely occur in the right atrium. Thus, the presentation of atrial fibrillation and premature atrial contractions (PAC) due to a solitary cardiac rhabdomyoma is an extremely rare scenario. Our literature review found that only 2% (1 out of 61) of rhabdomyoma cases were found in the right atrium. The majority of fetal cardiac rhabdomyomas are associated with tuberous sclerosis complex (TSC). CASE PRESENTATION A 7-day-old male neonate presented with arrhythmias and an atrial mass for further evaluation. Echocardiography revealed a hyperechoic, round, uniform right atrial mass (25 mm). An abdominal and testicular ultrasound showed multiple thin-walled cortical cysts in both kidneys and a scrotal hydrocele, respectively. His laboratory workup was insignificant except for hypomagnesemia. Electrocardiography revealed junctional rhythm and PACs with wave distortions. A brain magnetic resonance imaging scan revealed multiple subependymal lesions on the frontal and occipital horns of the lateral ventricles. These findings (Fig. 1), along with a family history of TSC, confirmed the diagnosis of TSC with associated CR. The patient was treated symptomatically with an anti-convulsant and monitored with regular follow-ups. Surgical resection was not required. CONCLUSION Despite CR's predominance in the ventricles, a diagnosis of rhabdomyoma should be kept in mind in the presence of a solitary atrial mass and PACs. Physicians should evaluate systemic findings related to TSC and provide appropriate follow-up and family screening. Surgical resection is not always required, and symptom management can be achieved through medical treatment alone.

Abstract
Tuberous sclerosis complex (TSC) is a multisystem disorder characterized by seizures, neuropsychiatric disorders, and tumors of the heart, brain, skin, lungs, and kidneys. We present a three-year follow-up of a patient with TSC-associated rhabdomyoma detected in utero. Genetic examination of the fetus and the parents revealed a de novo variant in the TSC2 gene (c.3037delG, p.Asp1013IlefsTer3). Oral everolimus was initiated in the pregnant mother to regress the fetal tumor, which was successful. To the best of our knowledge, there is very little information regarding the use of everolimus therapy during pregnancy. West-syndrome was diagnosed when the proband was four months old. The symptoms were well-manageable, however temporarily. Therapy-resistant focal seizures were frequent. The patient had good vitals and was under regular cardiological control, showed a balanced circulation, and did not require any medication. Subependymal giant cell astrocytoma (SEGA) identified by regular neuroimaging examinations remained unchanged, which may be a consequence of early intrauterine treatment. Early detection of the pathogenic TSC2 variant, followed by in utero administration of everolimus and early vigabatrin therapy, allowed the detection of a milder developmental delay of the proband. Our study emphasizes how early genetic testing and management of epilepsy are pivotal for proper neurodevelopmental impacts and therapeutic strategies.

Abstract
Tuberous sclerosis complex (TSC) is a multisystem genetic disorder characterized by the growth of numerous noncancerous tumors in many parts of the body. It is highly variable in clinical presentations, including a wide range of cognitive, behavioral, and psychiatric manifestations. Of all the possible manifestations, cognitive and behavioral problems are the greatest concern to parents and physicians. In this study, two fetuses were identified to have rhabdomyomas by prenatal ultrasound. Carefully inquired familial medical history revealed other symptoms of TSC such as skin lesions or psychiatric problems in family members in the two families. Both fetuses and family members with positive clinical symptoms were confirmed to carry a familial TSC2 variant. Our study indicates that fetal echocardiography is not just the evaluation of the fetal heart. When fetal cardiac rhabdomyomas are diagnosed, a full family medical history and clinical assessment for TSC in family members should be undertaken.

Abstract
Studying cardiac masses is one of the most challenging tasks for cardiac imagers. The aim of this review article is to focus on the modern imaging of cardiac masses proceeding through the most frequent ones. Cardiac benign masses such as myxoma, cardiac papillary fibroelastoma, rhabdomyoma, lipoma, and hemangioma are browsed considering the usefulness of most common cardiovascular imaging tools, such as ultrasound techniques, cardiac computed tomography, cardiac magnetic resonance, and in the diagnostic process. In the same way, the most frequent malignant cardiac masses, such as angiosarcoma and metastases, are highlighted. Then, the article browses through nontumoral masses such as cysts, mitral caseous degenerative formations, thrombi, and vegetations, highlighting the differential diagnosis between them. In addition, the article helps in recognizing anatomic normal variants that should not be misdiagnosed as pathological entities.

Abstract
BACKGROUND Rhabdomyoma is the most common cardiac tumour in children. It is usually associated with tuberous sclerosis complex caused by mutations in TSC-1 or TSC-2 genes. This tumour typically regresses by unknown mechanisms; however, it may cause inflow or outflow obstruction that necessitates urgent surgery. Here we investigate the clinical features and the genetic analysis of patients with tuberous sclerosis complex presenting with large rhabdomyoma tumours. We also investigate the potential role of autophagy and apoptosis in the pathogenesis of this tumour. METHODS All the patients with cardiac rhabdomyoma referred to Aswan Heart Centre from 2010 to 2018 were included in this study. Sanger sequencing was performed for coding exons and the flanking intronic regions of TSC1 and TSC2 genes. Histopathological evaluation, immunohistochemistry, and western blotting were performed with P62, LC3b, caspase3, and caspase7, to evaluate autophagic and apoptotic signaling. RESULTS Five patients were included and had the clinical features of tuberous sclerosis complex. Three patients, who were having obstructive tumours, were found to have pathogenic mutations in TSC-2. The expression of two autophagic markers, P62 and LC3b, and two apoptotic markers, caspase3 and caspase7, were increased in the tumour cells compared to normal surrounding myocardial tissue. CONCLUSION All the patients with rhabdomyoma were diagnosed to have tuberous sclerosis complex. The patients who had pathogenic mutations in the TSC-2 gene had a severe disease form necessitating urgent intervention. We also demonstrate the potential role of autophagy and apoptosis as a possible mechanism for tumourigenesis and regression. Future studies will help in designing personalised treatment for cardiac rhabdomyoma.

Abstract
Cardiac rhabdomyoma is a hamartoma comprised of cardiac myocytes. It is the classic cardiac manifestation of tuberous sclerosis complex (TSC) which is an autosomal dominant genetic syndrome with multi-organ involvement, but highly variable phenotype. Cardiac rhabdomyoma is most commonly diagnosed in infancy, 70 to 90% of whom have TSC. However, TSC-associated cardiac rhabdomyoma usually shows spontaneous regression within the first two years of life and hence is extremely rare in adults. We present a 34-year-old woman with TSC who was found to have a cardiac rhabdomyoma when she was referred to the cardiology clinic for evaluation and to establish care. Cardiac rhabdomyoma is usually asymptomatic. However, depending on size and location, it can cause outflow or inflow tract obstruction and aberrant electrical conduction. Hence, appropriate surveillance is important.

Benign Structures Mimicking Right Atrial Masses on Prenatal Ultrasound. Case Rep Pediatr 2021; 2021:8889941.

Abstract
Advances in imaging have resulted in more frequent reporting of primitive right atrial structures which can sometimes mimic cardiac tumors in prenatal ultrasound. Prominent crista terminalis and Chiari network are examples of these structures. We describe two cases of pregnant women referred to the fetal cardiology clinic for fetal echocardiography for right atrial masses seen on prenatal ultrasound suspicious of tuberous sclerosis. The first case subsequently diagnosed as crista terminalis and the second case as a prominent Chiari network. Postnatal ECHO confirmed the benign nature of these structures. It is important to differentiate tumors from prominent benign structures in the right atrium in fetal ECHO. The location and the similar echogenicity to the adjacent atrial tissue are clues for differentiation of these structures from atrial tumors.

Abstract
Cardiac neoplasms are a diagnostic challenge on many levels. They are rare, their clinical presentation may mimic other much more common cardiac diseases, and they are at an uncommon intersection of oncologic and cardiac imaging. The pathology of primary cardiac neoplasms explains their varied imaging features, for example, calcification in primary cardiac osteosarcomas and T2 hyperintensity in myxomas. Integrating the imaging and pathologic features of cardiac tumors furthers our understanding of the spectrum of appearances of these neoplasms and improves the clinical imager's ability to confidently make a diagnosis.

Abstract
Tuberous sclerosis complex (TSC) is characterized by the growth of benign tumors in the skin, brain, kidneys, lung and heart [1]. Prognosis is mostly determined by the extent of brain involvement as tumors in the brain lead to seizures, cognitive impairment and behavioral problems. Current evidence suggests anti-epileptic treatment before the onset of seizures reduces epilepsy severity and risk of cognitive impairment in TSC however identifying these children prior to the onset of seizures is challenging. Our case shows retrospectively reviewed antenatal ultrasounds of a male child diagnosed postnatally at 12 days of life with TSC. Analysis found a soft tissue mass in the right ventricle on antenatal ultrasound which was not captured in the initial ultrasound report. Though there are no reports of sensitivity of neurosonography for the antenatal detection of intracranial abnormalities associated with TSC, our case suggests that antenatal ultrasound could be used as a screening modality for antenatal diagnosis of TSC.

Abstract
Cardiac tumors in neonates and infancy are one among the many known congenital cardiac diseases. Although fetal cardiac tumors are rare, there is increased detection because of expertise in echocadiographic examination. Rhabdomyomas are the most common cardiac tumors among infants and children. Here, we describe twin neonates who had multiple cardiac tumors. This kind of presentation appears to be a very rare situation.

Abstract
OBJECTIVE The aim of this study is to review our institution's experience with fetal cardiac rhabdomyoma, and to document the prenatal genetic testing for tuberous sclerosis complex (TSC) and clinical outcome of the affected pregnancies. STUDY DESIGN During a four-year period, patients with fetal cardiac rhabdomyoma were detected by echocardiography in the second trimester of pregnancy. Molecular genetic analysis was conducted on fetuses to screen for variants of TSC1/TSC2 genes. We reviewed medical records of these affected pregnancies, including maternal demographics, sonographic findings, genotyping results and pregnancy outcomes. RESULTS Eleven cases with fetal cardiac rhabdomyoma were studied during the study period. A pathogenic variant of TSC1/TSC2 genes was detected in all cases, including two with an inherited variant and nine with a de novo variant. Out of these eleven cases diagnosed prenatally, eight pregnancies were terminated and three continued till term. CONCLUSIONS Cardiac rhabdomyoma is the prenatal sign of TSC. A molecular investigation of TSC1/TSC2 genes should be recommended for fetuses with a rhabdomyoma and the parents, and the prognostic counselling should include TSC and its consequences.

Abstract
Phakomatoses present with characteristic findings on the skin, central or peripheral nervous system, and tumors. Neurofibromatosis type 1 is the most common syndrome and is characterized by Café-au-lait macules, intertriginous freckling, Lisch nodules, and tumors including neurofibromas, malignant peripheral nerve sheath tumors, and gliomas. Tuberous Sclerosis Complex is characterized by benign hamartomas presenting with hypomelanotic macules, shagreen patches, angiofibromas, confetti lesions and tumors including cortical tubers, subependymal nodules, subependymal giant cell astrocytomas and tumors of the kidney, lung, and heart. Managing these disorders requires disease specific supportive care, tumor monitoring, surveillance for selected cancers, and treatment of comorbid conditions.

Abstract
Tuberous sclerosis complex (TSC) is an autosomal dominant syndrome characterized by mostly benign tumors of the brain, skin, heart, kidney, and eye. Aberrations in the genes TSC1 and TSC2 which encode hamartin and tuberin, respectively, cause TSC. Because disease manifestations develop over time, early diagnosis and intervention are imperative for patients. TSC is not well described in patients from sub-Saharan Africa or of black African ancestry. Here, we report on a 4-year-old Nigerian boy with skin lesions and cardiac anomalies associated with TSC. Furthermore, we note that in areas with limited resources for genetic diagnoses, the common skin manifestations found in TSC may be especially useful clinical markers.

Abstract
Of the subtypes of extracardiac rhabdomyoma, genital rhabdomyoma is most uncommon and is occasionally classified as fetal rhabdomyoma due to morphologic similarities. In contrast to other forms of rhabdomyoma, the genetic alterations of genital rhabdomyoma are unknown. The clinical and pathologic findings in 12 cases were reviewed and 2 cases were processed for whole genome copy number analysis by single nucleotide polymorphism microarray. Twelve patients ranged in age from 43 to 65 yr (mean: 50.2 yr). Nine tumors arose in the vagina and 3 in the cervix, with their greatest dimension spanning 0.9 to 1.7 cm (mean: 1.4 cm). Follow-up was available for 7 patients and none had evidence of recurrence (67-263 mo, mean: 153.7 mo). No somatic copy number alterations, particularly involving genes in Hedgehog signaling, were identified by microarray. Although genital rhabdomyoma has sufficiently unique clinicopathologic characteristics including age of onset and organs of involvement to distinguish it from fetal rhabdomyoma, the genetic mechanisms underlying its development are unclear given the lack of copy number variation and loss of heterozygosity by single nucleotide polymorphism microarray.

Abstract
Imaging of tuberous sclerosis complex has rapidly evolved over the last decade in association with increased understanding of the disease process and new treatment modalities. Tuberous sclerosis complex is best known for the neurological symptoms and the associated neuroimaging findings, and children with tuberous sclerosis complex require active surveillance of associated abnormalities in the chest, abdomen and pelvis. Common findings that require regular imaging surveillance are angiomyolipomas in the kidneys and lymphangioleiomyomatosis in the chest. However multiple rarer associations have been attributed to tuberous sclerosis complex and should be considered by radiologists reviewing any imaging in these children. In this review the authors discuss the spectrum of imaging findings in people with tuberous sclerosis complex, focusing on MR imaging findings in the chest, abdomen and pelvis.

Abstract
Cardiac tumors are rarely diagnosed in utero. Rhabdomyomas are the most common fetal cardiac tumors. They are usually diagnosed during the first year of life after obstruction of a valve orifice or a cardiac chamber; but they can be detected by echocardiography as early as the second trimester. Rhabdomyomas are usually small. Fetal hydrops and pericardial effusion are rare. The most important indication of tuberous sclerosis in the prenatal period is cardiac rhabdomyoma. Early diagnosis of cardiac rhabdomyoma is thus important for early diagnosis of tuberous sclerosis. This case report concerns the prenatal diagnosis of both multiple fetal cardiac rhabdomyomas and tuberous sclerosis. Rhabdomyomas are the most common fetal cardiac tumors. Cardiac rhabdomyomas may be the earliest sign of tuberous sclerosis in utero. Hamartomas occur in several organs in cases of tuberous sclerosis. Tuberous sclerosis should be kept in mind in cases of fetal cardiac rhabdomyoma.

Abstract
Various cardiac tumors occur in the setting of a genetic syndrome such as myxomas in Carney complex and rhabdomyomas in tuberous sclerosis. Tumor biology can be different in syndromic forms, and on imaging children sometimes demonstrate additional manifestations of the underlying syndrome. We discuss the imaging appearance of cardiac tumors occurring in the framework of a genetic syndrome, the findings that suggest an underlying syndrome, and the impact on management.

Abstract
The purpose of this article is to review the hereditary renal cystic diseases that can manifest in children and adults, with specific attention to pathogenesis and imaging features. Various common and uncommon hereditary renal cystic diseases are reviewed in terms of their underlying etiology, including the involved genetic mutations and the affected proteins and cellular structures. Focus is placed on the morphologic findings in each condition and the features that distinguish one disorder from another. The two most common categories of hereditary renal cystic disease are (a) the ciliopathic disorders, which are related to mutations affecting the primary cilia (called "ciliopathies"), and (b) the phakomatoses. Autosomal dominant polycystic kidney disease, autosomal recessive polycystic kidney disease, and the "medullary cystic disease complex" are all ciliopathies but have different phenotypes. Tuberous sclerosis complex and the associated "contiguous gene syndrome," as well as von Hippel-Lindau syndrome, are phakomatoses that can manifest with cystic renal lesions but have uniquely different extrarenal manifestations. Finally, DICER1 mutations can manifest with renal cystic lesions (typically, cystic nephromas) in patients predisposed to other malignancies in the chest, ovaries, and thyroid. Although some overlap exists in the appearance of the renal cysts associated with each of these diseases, there are clear morphologic differences (eg, cyst size, location, and complexity) that are emphasized in this review. To improve patient outcomes, it is important for the radiologist to recognize the various hereditary renal cystic diseases so that a correct diagnosis is assigned and so that the patient is adequately evaluated and followed up. ©RSNA, 2017.

Abstract
Tuberous sclerosis complex (TSC) is an autosomal dominantly inherited disorder with variable expressivity associated with hamartomatous tumors, abnormalities of the skin, and neurologic problems including seizures, intellectual disability, and autism. TSC is caused by pathogenic variants in either TSC1 or TSC2. In general, TSC2 pathogenic variants are associated with a more severe phenotype than TSC1 pathogenic variants. Here, we report a pathogenic TSC2 variant, c.1864C>T, p.(Arg622Trp), associated with a mild phenotype, with most carriers meeting fewer than two major clinical diagnostic criteria for TSC. This finding has significant implications for counseling patients regarding prognosis. More patient data are required before changing the surveillance recommendations for patients with the reported variant. However, consideration should be given to tailoring surveillance recommendations for all pathogenic TSC1 and TSC2 variants with documented milder clinical sequelae. © 2017 Wiley Periodicals, Inc.

Abstract
We report a newborn female baby who presented at 6 hours of age with cyanosis without any signs of respiratory distress. Cardiovascular and systemic examination was unremarkable apart from cyanosis (saturation 75%). An echocardiogram showed multiple echogenic and homogeneous masses in the interventricular septum, one of which was big and protruding through the tricuspid valve causing right ventricular inflow obstruction. There was a small atrial septal defect (ASD) shunting right to left and patent ductus arteriosus (PDA) shunting left to right. The provisional diagnosis was rhabdomyoma. Blalock-Taussig shunt was done to preserve the tricuspid valve, because these masses tend to regress spontaneously, which was the case after few months. Subsequently, the patient was diagnosed with tuberous sclerosis.

Abstract
An understanding of the role of inherited cancer predisposition syndromes in pediatric tumor diagnoses continues to develop as more information is learned through the application of genomic technology. Identifying patients and their relatives at an increased risk for developing cancer is an important step in the care of this patient population. The purpose of this review is to highlight various tumor types that arise in the pediatric population and the cancer predisposition syndromes associated with those tumors. The review serves as a guide for recognizing genes and conditions to consider when a pediatric cancer referral presents to the genetics clinic.

Abstract
Renal lesions represent the second most significant cause of morbidity and mortality in patients with tuberous sclerosis complex (TSC). Recent advances in the understanding of the pathophysiology of TSC have led to the exploration of new potential therapeutic targets. Clinical trials with mammalian target of rapamycin (mTOR) inhibitors have demonstrated promising results for several indications, such as renal angiomyolipoma, subependymal giant cell astrocytoma, lymphangioleiomyomatosis and facial angiofibromas. Currently, there is a scarcity of natural history data and randomized, placebo-controlled clinical trials on TSC. Recently, however, recommendations for the diagnostic criteria, surveillance, and management of TSC patients have been updated. This review focuses on these novel recommendations and highlights the need for multidisciplinary follow-up of this multi-systemic disease.

Abstract
UNLABELLED Cardiac rhabdomyoma is the most common primary cardiac tumor, is considered to be a hamartoma of developing cardiac myocytes. Cardiac rhabdomyoma is associated with tuberous sclerosis complex (TSC) in 50-86% of cases. Mutations in TSC-1/TSC-2 genes result in increased mammalian target of rapamycin (mTOR) pathway activation responsible for the hamartomatous lesions of tuberous sclerosis complex. Therapy with mTOR inhibitors is currently under investigation as a treatment option for tumors associated with TSC. In this report we present a case with multiple symptomatic rhabdomyomas associated with tuberous sclerosis complex, deemed to be ineligible for surgical removal, treated with everolimus (mTOR inhibitor). CONCLUSION As we observed in our patient, in cases with inoperable symptomatic rhabdomyomas associated with TSC, everolimus, an mTOR inhibitor, may be the treatment of choice, which should be confirmed with additional studies.

Abstract
Cardiac rhabdomyomas are benign cardiac tumours and are often associated with tuberous sclerosis. They are often asymptomatic with spontaneus regresion but can cause heart failure, arrhythmias, and obstruction. There have also been a few isolated reports of Wolff-Parkinson-White syndrome occurring in association with tuberous sclerosis and the great majority has been detected in patients with concomitant rhabdomyomas. We report a 12-day-old infant girl with tuberous sclerosis who presented with intraparietal and intracavitary rhabdomyomas with a Wolff-Parkinson-White syndrome (WPW). She represents one of the few published cases of WPW syndrome and tuberous sclerosis and particularly interesting because of intramural rhabdomyomas regression with persistent intracavitary rhabdomyomas after two years of followup.

Abstract
Cardiac rhabdomyoma (CR) is a rare tumor commonly associated with tuberous sclerosis. They are often detected prenatally or in early infancy. The case of a Nigerian human immunodeficiency virus (HIV)-exposed neonate with CR who presented with supraventricular tachycardia and cardiovascular collapse is presented. The infant was born to a mother on highly active antiretroviral therapy (HAART). The possible role of HIV and HAART in CR etiology and the difficulty in the management of this case are highlighted.

Abstract
Cardiac tumors are an uncommon cause for neurologic disease, but if undiagnosed can be associated with devastating neurologic consequences. Primary cardiac tumors, both benign and neoplastic, and metastatic tumors occur. Primary cardiac tumors are more likely to be associated with neurologic embolic complications. Metastatic cardiac tumors are more likely to be associated with valvular distraction, arrhythmia, diminished cardiac output and indirect neurological dysfunction. Primary and metastatic cardiac tumors may result in cerebral metastatic disease. Atrial myxoma, a benign primary cardiac tumor, is the most common cardiac tumor associated with neurologic disease, and most commonly causes cerebral embolization and stroke. The use of thrombolytic therapy for these strokes is controversial. Additionally, delayed manifestations, including aneurysm formation and intracranial hemorrhage, are possible. Aneurysm formation has been described as occurring after removal of the primary tumor. The availability of noninvasive cardiac imaging has significantly helped decrease the neurologic morbidity of cardiac tumors and has led to frequent successful intervention.

Abstract
BACKGROUND Tuberous sclerosis complex is highly variable in clinical presentation and findings. Disease manifestations continue to develop over the lifetime of an affected individual. Accurate diagnosis is fundamental to implementation of appropriate medical surveillance and treatment. Although significant advances have been made in the past 15 years in the understanding and treatment of tuberous sclerosis complex, current clinical diagnostic criteria have not been critically evaluated or updated since the last clinical consensus conference in 1998. METHODS The 2012 International Tuberous Sclerosis Complex Consensus Group, comprising 79 specialists from 14 countries, was organized into 12 subcommittees, each led by a clinician with advanced expertise in tuberous sclerosis complex and the relevant medical subspecialty. Each subcommittee focused on a specific disease area with important diagnostic implications and was charged with reviewing prevalence and specificity of disease-associated clinical findings and their impact on suspecting and confirming the diagnosis of tuberous sclerosis complex. RESULTS Clinical features of tuberous sclerosis complex continue to be a principal means of diagnosis. Key changes compared with 1998 criteria are the new inclusion of genetic testing results and reducing diagnostic classes from three (possible, probable, and definite) to two (possible, definite). Additional minor changes to specific criterion were made for additional clarification and simplification. CONCLUSIONS The 2012 International Tuberous Sclerosis Complex Diagnostic Criteria provide current, updated means using best available evidence to establish diagnosis of tuberous sclerosis complex in affected individuals.

Abstract
Cardiac tumours in infancy are rare and are mostly benign with rhabdomyomas, fibromas and teratomas accounting for the majority. The presentation depends on size and location of the mass as they tend to cause cavity obstruction or arrhythmias. Most rhabdomyomas tend to regress spontaneously but fibromas and teratomas generally require surgical intervention for severe haemodynamic or arrhythmic complications. Other relatively rare cardiac tumours too are discussed along with an Indian perspective.

Abstract
Adult rhabdomyoma (AR) is an extremely uncommon benign neoplasm with mature skeletal muscle differentiation comprising approximately 2% of muscle tumors, usually affecting the soft tissue of the head and neck. Although histology of AR is characteristic, several differential diagnoses (granular cell tumor, hibernoma, oncocytoma) should be considered, and one needs to be familiar with this rare entity to exclude other neoplastic diseases. We present a case of AR, in a 54-year-old man, affecting the floor of the mouth, and call attention to the oncocytic appearance (including antimitochondrial and peroxiredoxin I immunoreactivity) of this case and its differential diagnosis analyzed at the optical, immunohistochemical, and ultrastructural level, showing the morphological and immunohistochemical features that can be confused with a salivary oncocytoma.

Abstract
Rhabdomyomas are the most common primary cardiac tumors in childhood. They usually occur on ventricular and septal walls. In approximately half of the cases, rhabdomyoma is associated with tuberous sclerosis. Most rhabdomyomas regress during the first years of life. We present MRI findings of fatty replacement of the myocardium which was probably after spontaneous regression of solid mass (rhabdomyoma) in a 16-year-old boy with tuberous sclerosis.

Abstract
Tuberous sclerosis complex (TSC) is a genetic neurocutaneous disorder that commonly affects the CNS. The most commonly associated brain tumors include cortical tubers, subependymal nodules, and subependymal giant cell astrocytomas (SEGAs). The authors report an unusual case of recurrent meningitis due to a tuber-containing encephalocele via the posterior wall of the frontal sinus. An 11-year-old girl presented with a history of TSC and previous SEGA resection via interhemispheric approach. She presented twice within 4 months with classic bacterial meningitis. Cerebrospinal fluid cultures revealed Streptococcus pneumoniae. Computed tomography and MR imaging of the brain showed a right frontal sinus encephalocele via a posterior frontal sinus wall defect. Both episodes of meningitis were treated successfully with standard regimens of intravenous antibiotics. The neurosurgical service was consulted to discuss surgical options. Via a bicoronal incision, a right basal frontal craniotomy was performed. A large frontal encephalocele was encountered in the frontal sinus. The encephalocele was herniating through a bony defect of the posterior sinus wall. The encephalocele was ligated and resected followed by removing frontal sinus mucosa and complete cranialization of frontal sinus. Repair of the sinus floor was conducted with fat and pericranial grafts followed by CSF diversion via lumbar drain. Histopathology of the resected encephalocele showed a TSC tuber covered with respiratory (frontal sinus) mucosa. Tuber cells were diffusely positive for GFAP. The patient underwent follow-up for 2 years without evidence of recurrent meningitis or CSF rhinorrhea. This report demonstrates that frontal tubers of TSC can protrude into the frontal sinus as acquired encephaloceles and present with recurrent meningitis. To the authors' knowledge, recurrent meningitis is not known to coincide with TSC. Careful clinical and radiographic follow-up for frontal tubers in patients with TSC is recommended.

Abstract
Tuberous sclerosis complex is a genetic multisystem disease characterized by hamartic development of many organs, most notably the brain, heart, kidneys, lungs, and skin. This autosomic dominant disorder results from mutations in one of two genes, TSC1 and TSC2, coding for hamartin and tuberin, respectively. The hamartin-tuberin complex inhibits the mammalian target of rapamycin pathway, which controls cell growth and proliferation. The clinical presentation is highly variable and most features of tuberous sclerosis become evident only in childhood after the child is several years of age, limiting their usefulness for early diagnosis. The aim of this article is to define the pediatric clinical manifestations of tuberous sclerosis in correlation with patient age. Sometimes, a prenatal diagnosis can be made based on fetal ultrasound and MRI, which show cardiac and brain lesions. However, newborns are most often asymptomatic. In the 1st year, seizures are the most common symptoms, with a high incidence of infantile spasms. In children between 2 and 10 years of age, neurological symptoms are the most frequent with epilepsy, mental retardation, and autism, but extraneurological manifestations can be diagnosed. In adolescents, most features of tuberous sclerosis become evident and renal and pulmonary manifestations must be sought. The knowledge of age-dependent clinical features of tuberous sclerosis can provide an earlier diagnosis and improve the management of these patients with a special role for multidisciplinary consultation.

Abstract
While most primary tumors of the heart are histologically benign, they are significant space-occupying lesions with serious functional implications for the heart and lungs. Herein, we highlight our experience with the surgical management of selected cardiac tumors in the pediatric population between 2008 and 2010. (1) Intrapericardial teratomas in the fetus can produce fatal tamponade from compression by the attendant pericardial effusion, and a critical life-saving maneuver preoperatively is to drain the effusion prenatally, followed by an expeditious resection after birth. (2) Rhabdomyomas, the most common of the pediatric cardiac tumors, can be intracavitary, large, and associated with the mitral subvalvular apparatus. (3) Cardiac fibromas should be aggressively resected or at least debulked, especially given their propensity for dysrrhythmias. The key to success is as complete a resection as possible, but not at the expense of other normal structures. (4) Complex nonobstructive hypertrophic myopathy can be thought of as a type of neoplastic overgrowth, and aggressive resection of even midcavitary obstructive lesions should be considered as a viable alternative to primary transplantation.
