Mulberry Tumors in Retina and Nasal Hamartoma in a Patient With Tuberous Sclerosis
Abstract
Introduction: Tuberous Sclerosis (TS) is an autosomal dominant disease that affects the brain, skin, eye, heart, kidney even bones. The commonest presentation is seizures in infancy or early childhood (in 80% of cases), mental retardation (in 44%of cases). Characteristic skin lesion includes facial angiofibromas, adenoma sebaceum, hypopigmented macules, shagreen patches ungual ungual fibromas, ash leaf spots, cafe'-au-lait spots. Case Report: A nine years old male was admitted in a pediatric hospital because of the status myoclonic seizures. Seizures had been started since infancy. In physical exam he had some hypopigmented macules, cafe'-au-lait spots and ash leaf lesions, frontal fibrosis and also shagreen patches. Patient was a case of mild mentally retardation with no any focal neurological deficit. Computed tomography scan of brain and MRI imaging revealed sub ependymal tubers with multiple calcification in both sides of parietal region. Electroencephal-ogram recording suggested abnormal spike, sharp wave discharges and lennox-Gastaut pattern. The diagnosis based on the history and physical exam and MRI were tuberous sclerosis. His foundoscopic exam revealed two prominent calcified mass around right optic disc in supratemporal arch, left eye was normal. Retinal angiography revealed the mulberry tumors and right phakoma of retina. Conclusion: Computed tomography also revaled the nasal hamartoma. Histopathologic examination confirmed the diagnosis of angiomyolipoma because the lesion was composed of smooth muscle bundles, mature adipose tissue and blood vessels of different sizes. He remained seizures free after treatment.
