RESUMEN
Tuberous sclerosis complex (TSC) is an inherited, multisystemic, hamartomatous neurocutaneous disorder, with an autosomal dominant inheritance pattern. It affects multiple organs, however the most susceptible ones include the brain, skin, kidneys, lungs, the retina, and the heart. TSC is characterized by considerable clinical heterogeneity. The majority of patients present with a constellation of clinical signs and symptoms, most prominently central nervous system manifestations including epilepsy, cognitive impairment and autism spectrum disorders, cutaneous, cardiac, renal and ophthalmic manifestations. Epilepsy affects 70% - 90% of patients, representing the primary neurological feature and 1 of the foremost clinical findings of the disorder. Cardiac rhabdomyomas are the most frequent cardiac manifestations, appearing as isolated or multiple lesions. Herein, we present 2 patients diagnosed with tuberous sclerosis. A 3-month-old male patient with cardiac rhabdomyomas and hypopigmented macules and a 19-month-old male patient with partial epilepsy and mild psychomotor retardation. As brain lesions represent some of the most prevalent clinical features and early onset seizures are associated with more severe cognitive, function delay, through this article we hope to emphasize the potential role MRI can play in the diagnostic workup of TSC, to ensure a more timely diagnosis, thus modifying the natural course of the disorder and its prognosis.
