(b) During the early excretory phase, the tumor shows an early washout pattern. Pulmonary involvement of TS includes lymphangioleiomyomatosis (LAM) and multifocal micronodular pneumocyte hyperplasia (MMPH). Unenhanced CT shows multiple, calcified nodules in a periventricular, subependymal distribution bilaterally in dilated lateral ventricles, characteristic of tuberous sclerosis. 7, Current Problems in Diagnostic Radiology, Vol. Introduction. It should be suspected when some of the common manifestations are found, including CNS involvement, renal AML, and cardiac rhabdomyoma, even if clinical signs are not obvious. The frequency of mutations in TSC2 is higher than in TSC1. Diagnosis The signs and symptoms of Tuberous Sclerosis Complex, and how it is diagnosed The age, time and background of a Tuberous Sclerosis Complex (TSC) diagnosis can vary dramatically between everyone living with the condition.

However, recent meta-analysis has shown that the overall incidence of renal cell carcinomas in patients with TS is identical to that in the general population (,52). Although unenhanced CT with thin sections is useful for detecting small amounts of fat, intratumoral fat cannot be detected in approximately 4.5% of all renal AMLs (,49).

When a mass is centered on the choroid plexus, a highly vascular tumor-either choroid plexus papilloma, choroid plexus carcinoma, meningioma, or metastasis-should be suspected. The prevalence of TSC is estimated to be 1:6,000 live births . At MR imaging, small well-demarcated lesions of similar intensity to that of cerebrospinal fluid with all sequences are seen in white matter (,Fig 7,).

Pulmonary manifestations are estimated to occur in approximately 1%–2.3% of TS patients, but recent reports indicate that pulmonary LAM can be found radiologically in 26%–39% of female patients with TS (,38). TS can affect both sexes and all ethnic groups. However, it should be recognized that half of TS patient… Clinically, patients with MMPH may present with dyspnea, cough, and mild to moderate hypoxemia. Figure 3. The lesions typically appear in adolescence as small red papules in the malar area, with a so-called “butterfly distribution” (,Fig 1). J Child Neurol. No mutation is identifiable in 15%–20% of TS patients, and these patients generally have milder clinical manifestations (,9). Coronal half-Fourier-acquisition single-shot turbo spin-echo (HASTE) MR image demonstrates bilateral loculated pleural effusion and ascites. The purpose of this article is to illustrate the various manifestations that can be encountered on thoracic computed tomography of tuberous sclerosis in adults. Angiomyolipomas are found in 40% patients with tuberous sclerosis; such lesions tend to bleed because of their hypervascularity and the presence of small aneurysms. 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). Renal AMLs with minimal fat in a 19-year-old man. Tuberous sclerosis complex (TSC) is an autosomal-dominant neurocutaneous disease with high phenotypic variability. Figure 9. 2004.

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. (a) Unenhanced CT image demonstrates high-attenuation tumor around the foramen of Monro (arrow). 205, No. TSC affects cellular degeneration, proliferation, and migration and results in hamartomatous lesions in virtually all organs during early development—most commonly the brain, skin, eyes, heart, kidneys, and lungs. In such cases, biphasic contrast-enhanced CT may be useful for differentiating these two entities (,49). The probability of rupture depends on the formation of an aneurysm, which is related to the size of the renal AML (,48). Figure 11. 7, American Journal of Roentgenology, Vol. However, the diagnosis of tuberous sclerosis can be made earlier or later on the basis of other features that manifest themselves at other ages. Radial white matter bands in an 8-month-old boy. Tuberous sclerosis is characterized by a variety of hamartomatous lesions in various organs. 35, No. Tuberous sclerosis is a genetic disorder, where cellular differentiation and proliferation result in hamartoma formation in the skin, brain, eye, kidney, and heart. Hyperattenuating material suggestive of hemorrhage is also seen in and around the tumor. 2003; 23 (1):241–246. Although their exact frequency is unknown, that estimated by Stillwell et al is 18%–53% (,46).
