MMPH is a rare disorder that has been described in few literature reports. T1: low signal; T2/FLAIR: high signal (except neonatal period, see below) T1 C+ (Gd): enhancement only demonstrated in <10% of cases 1,8 They usually involve cerebral white matter bilaterally (predominantly frontal lobes) and uncommonly cerebellar white matter (,16). Tuberous sclerosis is a rare autosomal dominant neurocutaneous syndrome characterized by the presence of benign congenital tumors in multiple organs. TS has been considered to be caused by mutations of two genes known as TSC1 and TSC2. If they are altered by mutation, disturbed control of cell growth results in formation of tumors throughout the body. A variety of subtypes of renal call carcinoma, including clear cell, papillary, and chromophobe carcinoma have been reported in patients with TS (,9). Contrast-enhanced CT image shows multiple renal cysts bilaterally.

(a, b) Contrast-enhanced CT images of different levels demonstrate multiple high-attenuation polypoid lesions (arrows) in the small intestine. They are generally detected in infancy or early childhood and are typically round at one end and tapered at the other. Typical CT findings of renal AMLs are noncalcified cortical tumors containing fat of less than −20 HU (,Fig 13) (,45). 207, No. The estimated prevalence of cortical tuber and/or subependymal nodule is 95%–100% and that of white matter abnormalities is 40%–90% (,11). Rarely, renal cell carcinoma and oncocytoma may also occur in patients with TS (,9). (a, b) Contrast-enhanced CT images of different levels demonstrate multiple high-attenuation polypoid lesions (arrows) in the small intestine.

Tuberous Sclerosis. They are often found in association with tuberous sclerosis complex (TSC). Left renal AML is also seen (arrowheads). Pneumothorax and chylous pleural effusion or ascites are two major complications of LAM. In such cases, biphasic contrast-enhanced CT may be useful for differentiating these two entities (,49). Figure 22. 2008 Jan-Feb;28(1):65-79; • Avila NA, Dwyer AJ, Rabel A, Moss J. Tuberous sclerosis complex (TSC) is a rare multisystem genetic disease. 45, No. Some reports described that some gastrointestinal polyps show early malignant change (,56). Pictorial review of tuberous sclerosis in various organs. 30, No. (b) Axial fluid-attenuation inversion-recovery MR image also demonstrates cortical tubers as hyperintense foci (arrows). Pulmonary involvement of TS includes lymphangioleiomyomatosis (LAM) and multifocal micronodular pneumocyte hyperplasia (MMPH). Although the pancreas is a rare organ for manifestations of TS, hypoplasia, islet-cell tumor, hamartoma, and mucoviscidosis have been reported (,56). 2011; 118:e15–20. Rarely, ulceration, fibrous tumors, vascular malformations, adenocarcinomas, and leiomyomas (,Fig 20) have been reported to be associated with TS (,56,,57). This patient has bilateral renal angiomyolipomas, which is commonly associated with tuberous sclerosis. 0000046530 00000 n Figure 10. 43, No. Patients can present with a variety of symptoms, … Subependymal calcified tubers in a 9-month-old boy. CT image of the chest demonstrates multiple lung cysts, suggesting pulmonary LAM. Superficial white matter abnormalities are related to almost all cortical tubers. 1, Journal of Computer Assisted Tomography, Vol. Subependymal giant cell astrocytoma in a 24-year-old man. We explored pancreatic neuroendocrine tumors (PanNETs) associated with tuberous sclerosis complex (TSC) to determine their incidence in the TSC population; define their clinical, radiological, and pathological characteristics; and investigate their association with underlying genotypes. The tumor was surgically proved to be leiomyoma of the jejunum.Download as PowerPointOpen in Image Most cardiac rhabdomyomas regress before birth, and more than 80% of the tumors cause no clinical manifestations at birth (,35). 1, 13 July 2018 | Journal of Patient-Reported Outcomes, Vol. Figure 13. 3 Lymphangiectasia within angiomyolipoma in a tuberous sclerosis patient White matter cystlike lesions are located in deep white matter, typically near the lateral ventricles (,11). Pneumothorax associated with pulmonary LAM in a 37-year-old woman. On examination skin lesions, mental retardation, and retinal hamartomas are frequently seen [3]. Aggressive drainage of chylous pleural effusions should be avoided because it may lead to protein loss. These lesions are considered rare, yet they are purported to occur in up to 44% of TS patients (,11). Renal involvement in tuberous sclerosis complex (TSC) is common and potentially serious. The most alarming complication of renal AMLs is rupture due to their abnormal vasculature, frequently associated with aneurysms. (a) Unenhanced CT image demonstrates multiple high-attenuation tumors in the kidneys.

MMPH is a rare pulmonary disorder that can be associated with TS. 52, No. Tuberous sclerosis complex (TSC) is a rare multisystem autosomal dominant genetic disease that causes non-cancerous tumours to grow in the brain and on other vital organs such as the kidneys, heart, liver, eyes, lungs and skin.A combination of symptoms may include seizures, intellectual disability, developmental delay, behavioral problems, skin abnormalities, lung disease, and kidney disease. Cortical tubers in a 40-year-old woman. 29, No. Subependymal tubers in a 26-year-old woman. A typical CT finding is bilateral multiple renal cysts in younger patients (,Fig 16). Tuberous sclerosis complex (TSC) is an autosomal-dominant neurocutaneous disease with high phenotypic variability. Introduction. Renal AMLs in a 38-year-old woman. Cardiac rhabdomyomas, which may be multiple or single, are commonly located on the ventricular septum. Patients with numerous cortical tubers tend to have more cognitive impairment and more difficulty with seizure control (,12). 4, Current Problems in Diagnostic Radiology, Vol. 0000007394 00000 n Radiologic assessment is useful not only in diagnosis but also in determining treatment.

The most common manifestation of gastrointestinal involvement is polyps, which are frequently multiple and can occur anywhere from the esophagus to the rectum (,Fig 19,,,). It is the second most common neurocutaneous syndrome after neurofibromatosis type 1 and has been recognized since the late 1800s. Calcified subependymal tubers are also seen. AJR.

Left renal AML is also seen (arrowheads). Arterial wall developmental disorders, such as aneurysms, in association with TSC have been well described for extracranial vasculature. Compared with sporadic lesions, AMLs seen in patients with TS tend to manifest at a younger age and to be multiple, larger, and bilateral and to grow (,47). It was surgically proved to be a chromophobe renal cell carcinoma.Download as PowerPointOpen in Image 2009 Aug;39(8):878. No mutation is identifiable in 15%–20% of TS patients, and these patients generally have milder clinical manifestations (,9). (a, b) Contrast-enhanced CT images of different levels demonstrate multiple high-attenuation polypoid lesions (arrows) in the small intestine. It is an autosomal-dominant neuro-cutaneous disorder characterised by tumour-like malformations involving many organ systems including brain, lungs, heart, kidneys and skin.1 Since 1995, the University Medical Center Utrecht has been a national referral centre for patients with TSC.
