1/45. Phakomatosis pigmentovascularis: A new case with renal angiomas and some considerations about the classification.We report phakomatosis pigmentovascularis detected in a Caucasian child characterized by the presence of a nevus flammeus and nevus anemicus on the face, a telangiectatic linear nevus of the right leg, and a very extensive blue spot covering 60% of the body surface, with ocular melanosis. Multiple angiomatous lesions of the kidney are associated without alterations of the central nervous system (CNS). This association has not been reported before; it could be a further expression of the complex of developmental defects. Our case corresponds exactly to type IIb in the classification of phakomatosis pigmentovascularis proposed by Hasegawa. As this classification seems very extensive, the higher incidence of cases corresponding to the second subtype suggests that we should identify it by the term phakomatosis pigmentovascularis, while the others could be considered as only very uncommon variants.- - - - - - - - - - ranking = 1keywords = central nervous system, nervous system (Clic here for more details about this article) |
2/45. Primary meningeal rhabdomyosarcoma in a child with hypomelanosis of Ito.Intracranial rhabdomyosarcomas are rare neoplasms, and those thought to be primary meningeal tumors are even more rare. Hypomelanosis of Ito is a neurocutaneous disorder believed to involve a defect in cells of neural crest origin. We report the case of a 15-month-old boy with hypomelanosis of Ito who developed a primary meningeal rhabdomyosarcoma. The patient initially presented with hydrocephalus and 2 months later developed neurologic signs localizing to the spinal cord. Radiologic studies revealed widespread leptomeningeal enhancement with compression of the spinal cord at C5-C7. A brain biopsy revealed a tumor diffusely involving the meninges. Microscopically, the tumor was composed of rhabdomyoblasts, many of which showed prominent cross-striations on routine hematoxylin-eosin staining. To the best of our knowledge, this is the first reported case of meningeal rhabdomyosarcoma in a patient with hypomelanosis of Ito and the fourth reported case of a primary meningeal rhabdomyosarcoma reported in the world literature.- - - - - - - - - - ranking = 0.10420353418029keywords = brain (Clic here for more details about this article) |
3/45. Hemimegalencephaly in hypomelanosis of Ito: early sonographic pattern and peculiar MR findings in a newborn.Sonography is a reliable tool for the evaluation of the most severe congenital abnormalities of the brain; in the present case it provided an early demonstration of hemimegalencephaly in hypomelanosis of Ito in a newborn affected by body hemihypertrophy and skin lesions. Serial magnetic resonance (MR) examinations confirmed the asymmetry of the cerebral hemispheres, and documented the evolution of the hemispheric growth and the presence of unusual aspects.- - - - - - - - - - ranking = 0.10420353418029keywords = brain (Clic here for more details about this article) |
4/45. 12-year-old male with Elejalde syndrome (neuroectodermal melanolysosomal disease).Neuroectodermal melanolysosomal disease, also known as Elejalde syndrome, is a rare syndrome characterized by silvery hair, pigment abnormalities, and profound central nervous system dysfunction. It is similar to the Chediak-Higashi and Griscelli syndromes, although these syndromes are associated with severe immunologic dysfunction. We report on a 12-year-old male with Elejalde syndrome and compare the Elejalde, Chediak-Higashi, and Griscelli syndromes.- - - - - - - - - - ranking = 1keywords = central nervous system, nervous system (Clic here for more details about this article) |
5/45. Sneddon's syndrome: a cause of cognitive decline in young adults.OBJECTIVE: To review the clinical, psychometric, laboratory, and radiologic findings of 6 patients with Sneddon's syndrome (SS) who presented with cognitive dysfunction rather than stroke. DESIGN AND methods: Case series. All patients fulfilled were diagnosed as SS based on the co-occurrence of livedo racemosa and neurologic disease. patients presenting with clinical stroke were excluded. RESULTS: patients presented with cognitive complaints at an early age and all noted skin lesions from 6 months to 10 years before onset of cognitive symptoms. Associated systemic disorders included hypertension and seizures. Laboratory evidence of a hypercoagulable condition was identified in 4 of 6 cases. brain MRI scans demonstrated atrophy, especially in parieto-occipital regions and cerebral blood flow on brain SPECT scan was reduced in a similar distribution. CONCLUSION: patients with SS can develop dementia without antecedent clinical stroke. While the specific pathogenic mechanism of dementia in SS remains speculative, the disease predominantly injures brain tissue in vascular "watershed" territories.- - - - - - - - - - ranking = 0.20840706836057keywords = brain (Clic here for more details about this article) |
6/45. lissencephaly and mongolian spots in Hurler syndrome.Hurler disease or syndrome is a disorder of mucopolysaccharide metabolism, inherited as an autosomal recessive trait. We describe a case of a 15-month-old female exhibiting with clinical and laboratory characteristics of the syndrome, central nervous system lesions (lissencephaly, excessive ventricular enlargement and Dandy Walker malformation with vermis atrophy, cerebellar cyst) and mongolian spots in the trunk and extremities. The combination of mongolian spots and severe central nervous system lesions in Hurler syndrome is considered a rare clinical occurrence, while the association with lissencephaly has never been reported.- - - - - - - - - - ranking = 2keywords = central nervous system, nervous system (Clic here for more details about this article) |
7/45. Elejalde syndrome: report of a case and review of the literature.Elejalde syndrome is a rare autosomal recessive condition, with only 10 reported cases through 2001. It is characterized by silvery hair, pigment abnormalities, and profound central nervous system dysfunction. The differential diagnosis includes Griscelli and Chediak-Higashi syndromes, which present with silvery hair, pigment abnormalities, central nervous system alterations, and severe immunologic dysfunction. We report a 6-year-old girl with Elejalde syndrome and review Elejalde, Griscelli, and Chediak-Higashi syndromes.- - - - - - - - - - ranking = 2keywords = central nervous system, nervous system (Clic here for more details about this article) |
8/45. Hypomelanosis of Ito and moyamoya disease.moyamoya disease is a cerebrovascular disease characterized by stenosis and occlusion of the arteries of the circle of willis, with abnormal telangiectatic collateral circulation at the base of the brain. An association between moyamoya disease and neurofibromatosis 1, a neurocutanoeus disorder, is well established in the literature. However, its association with other neurocutaneous syndromes is infrequently reported. Hypomelanosis of Ito, another neurocutaneous syndrome, is characterized by macular hypopigmented skin whorls and variable neurologic involvement. Only one case study of an association between hypomelanosis of Ito and moyamoya disease has been reported in the English literature. We report a 17-year-old girl with both hypomelanosis of Ito and angiographic moyamoya disease. She presented with intractable seizures, progressive left hemiparesis, and skin manifestations of hypomelanosis of Ito. Although one might consider a coincidental association, this second case points to an association between the two disorders. Detailed neuroimaging, in particular angiography, should be considered in children with hypomelanosis of Ito and abnormal neurologic findings.- - - - - - - - - - ranking = 0.10420353418029keywords = brain (Clic here for more details about this article) |
9/45. Hypomelanosis of Ito and hemimegalencephaly.Hypomelanosis of Ito is a congenital neurocutaneous syndrome with a particular pattern of swirling hypopigmentation. Multiple extracutaneous abnormalities involving the central nervous system, the eyes, and musculoskeletal structures occur in over two-thirds of the cases. This report describes two patients with typical unilateral cutaneous lesions associated with extracutaneous features, including hypertrophy of the cerebral hemisphere contralateral to the cutaneous hypopigmentation. magnetic resonance imaging and EEG findings support the diagnosis of hemimegalencephaly, as has recently been reported in other isolated cases of this rare phakomatosis.- - - - - - - - - - ranking = 1keywords = central nervous system, nervous system (Clic here for more details about this article) |
10/45. dystonia, mental deterioration, and dyschromatosis symmetrica hereditaria in a family with ADAR1 mutation.A family with dystonia associated with dyschromatosis symmetrica hereditaria (DSH), mental deterioration, and tissue calcification is described. The proband possessed an adenosine deaminase acting on the RNA 1 gene (ADAR1) mutation Gly1007Arg. This ADAR1 mutation could disturb rna editing at Q/R sites of glutamate receptor in the brain and increase Ca(2 ) influx into neurons, which is thought to induce dystonia and mental deterioration. The observations in our family raise the possibility that the ADAR1 mutation might be a direct cause or a predisposing factor for heredodegenerative dystonia. Further investigation of ADAR1 mutations will shed light on the genotype-phenotype correlation in DSH.- - - - - - - - - - ranking = 0.10420353418029keywords = brain (Clic here for more details about this article) |
