Tuberous sclerosis with pulmonary lymphangioleiomyomatosis and renal angiomyolipomas Computed tomographic findings: The disorder should be considered in cases of children with seizures and hypomelanotic macules. According to that hypothesis, patients with TSC would already present a defective tumor suppressor gene in one of the alleles of TSC1 or TSC2 during germ-cell division.

MMPH consists of multifocal nodular lesions related to the proliferation of type II pneumocytes, with mild thickening of the alveolar septa, particularly when extensive. Micronodular hyperplasia of type II pneumocytes-a new lung lesion associated with tuberous sclerosis.

The sign that most often leads to diagnosis of the syndrome is the presence of early-onset seizures. With this method, tubers may be associated with white matter abnormalities, such as radial migration lines. In that scenario, a detailed evaluation of the brain, kidney, lung, skin, teeth, heart and eye are crucial, and for most of these, imaging plays an important role, not only in diagnosing and determining the extent of tuberous sclerosis but also in the treatment planning and patient follow-up 346.
