1/34. Epidermal naevus syndrome and hypophosphataemic rickets: description of a patient with central nervous system anomalies and review of the literature.The epidermal naevus syndrome (ENS) is a rare dermatological condition consisting of congenital epidermal nevi associated with anomalies in the central nervous system, bones, eyes, hear or genito-urinary system. We report a new case of ENS associated with hypophosphataemic rickets. The girl was born with a mixed-type epidermal naevus and skeletal anomalies. Hypophosphataemic rickets was diagnosed at the age of 2.5 years. At 14 years of age. MRI of the head demonstrated right brain hypotrophy, a left temporal arachnoid cyst and asymmetric lateral ventricles. We reviewed the literature and found 13 reported cases of ENS associated with hypophosphataemic rickets. Conclusion We report a further patient with epidermal naevus syndrome and hypophosphataemic rickets, followed from birth to the age of 15 years, who had structural central nervous system anomalies with normal intellectual functioning. A comprehensive neurological work up is recommended in patients with epidermal naevus syndrome.- - - - - - - - - - ranking = 1keywords = central nervous system, nervous system, brain (Clic here for more details about this article) |
2/34. Linear epidermal nevus and nevus sebaceus syndromes: a clinicopathologic study of 3 patients.BACKGROUND: Linear epidermal nevus syndrome and linear sebaceus nevus syndrome are rare neurocutaneous syndromes characterized by epidermal nevi, epilepsy, and mental retardation. Pathologic descriptions of the central nervous system findings in such patients are rare. DESIGN: We examined the clinicopathologic features of 2 patients with linear epidermal nevus syndrome and 1 with nevus sebaceus syndrome who underwent surgical resections for chronic epilepsy in a tertiary referral center with a high volume of epilepsy surgery. RESULTS: patients included 3 females, aged 11 months (patient 1), 8 years (patient 2), and 2 1/2 years (patient 3) at the time of surgery. The duration of seizures prior to surgery was 11 months, 6 years, and 28 months, respectively. Two patients had epidermal nevi involving the head region (patients 1 and 3), and 1 had a nevus sebaceus of Jadassohn (patient 2); patient 2 had a choristoma, and patient 3 had a dermoid cyst in the eye region. Patient 1 demonstrated hemimegalencephaly radiographically. Histologic examination of resected cortical tissue in patients 1 and 2 demonstrated severe diffuse cortical dysplasia characterized by a disorganized cortical architectural pattern, a haphazard orientation of cortical neurons, and increased molecular layer neurons. Gyral fusion was seen in patient 1. Pial glioneuronal hamartomas were observed in patient 1. Prominent cortical astrocytosis was seen in patients 1 and 2, and foci of microcalcification were evident in patient 1. Cortical dysplasia was milder in patient 3 and consisted of an increased number of molecular layer neurons. Neuronal heterotopia was observed in all 3 patients. CONCLUSION: The spectrum of neuronal migration abnormalities in the setting of these syndromes may be variable in terms of its histologic phenotypic manifestations.- - - - - - - - - - ranking = 0.16494119298576keywords = central nervous system, nervous system (Clic here for more details about this article) |
3/34. renal artery stenosis associated with epidermal nevus syndrome.Epidermal nevus syndrome is an unusual neurocutaneous disorder in which epidermal nevi are associated with abnormalities of the skeleton and central nervous system, including the eyes and somtimes the cardiovascular system. We treated a patient in whom the latter included renal artery stenosis. An 18-year-old man with epidermal nevi was diagnosed as having the syndrome based on the additional presence of scoliosis, an arachnoid cyst in the middle cranial fossa, and microphthalmos. hypertension was diagnosed when the patient was 15 years old. The plasma renin activity (9.7 ng/ml/h) was elevated. Right renal artery stenosis was demonstrated by angiography, and the abdominal aorta was narrowed distal to the ostium of the superior mesenteric artery. The plasma renin activity in the right renal vein (16 ng/ml/h) was higher than contralaterally (10 ng/ml/h). Several cardiovascular manifestations have been reported as a complication of epidermal nevus syndrome. hypertension in an individual with epidermal nevi and congenital anomalies should prompt a search for a vascular anomaly.- - - - - - - - - - ranking = 0.16494119298576keywords = central nervous system, nervous system (Clic here for more details about this article) |
4/34. Neurocutaneous vascular hamartomas mimicking Cobb syndrome. Case report.The authors report the rare case of a patient with neurocutaneous vascular hamartomas mimicking Cobb syndrome. An 8-year-old boy was admitted to the authors' hospital with progressive urinary disturbance and upper back pain. Multiple skin nevi had been noted at the child's birth. Radiological examination revealed multiple cavernous angiomas in the spinal cord in the same metamere in which the skin nevi had been observed and also in the left cerebral hemisphere. His symptoms gradually improved without surgical intervention. Four years later he was readmitted because of a cerebral hemorrhage involving the left cerebral peduncle. Nonsurgical treatment was chosen because his symptoms promptly improved. To the best of the authors' knowledge, this is the first case of multiple cavernous angiomas in the brain and spinal cord associated with skin nevi. The authors discuss this clinical entity and the significance of the disease.- - - - - - - - - - ranking = 0.010352842085414keywords = brain (Clic here for more details about this article) |
5/34. Neurologic variant of epidermal nevus syndrome with a facial lipoma.A 1-year-old girl presented for evaluation of a linear plaque on her forehead. She was born at 36 weeks' gestation following an uncomplicated pregnancy and delivery. At birth, she was noted to have an enlarged right cheek. She had no seizure history, but developed grand mal seizures 1 year later. On examination, she had a yellow plaque on her forehead which extended onto her nose. Under her right jaw, extending onto her anterior neck, there was a cafe-au-lait macule within which there was a yellow plaque which followed the lines of Blaschko. Her right cheek was enlarged and was erythematous (Fig. 1). magnetic resonance imaging (MRI) of her face showed a mass in the right cheek deep to the subcutaneous fat tissue layer. The signal from the mass was identical to that from the fat, indicating that the mass represented a lipoma. This was later excised surgically and was histologically a lipoma. MRI of the brain demonstrated enlargement of the right lateral ventricle in addition to enlargement of the right cerebral hemisphere. There was also evidence of abnormal gyral architecture. Computerized tomography (CT) three-dimensional reconstruction of the skull demonstrated overgrowth of the right maxilla, right mandible, and right orbit (Fig. 2).- - - - - - - - - - ranking = 0.010352842085414keywords = brain (Clic here for more details about this article) |
6/34. Linear nevus sebaceous syndrome associated with porencephaly and nonfunctioning major cerebral venous sinuses.An infant with the linear nevus sebaceous syndrome also had new findings of porencephaly and nonfunctioning major cerebral venous sinuses. This infant is the first described with the syndrome to undergo angiographic study. Similar nonfunctioning major cerebral venous sinuses are seen in the sturge-weber syndrome. A leptomeningeal angioma recently was reported in a newborn with the linear nevus sebaceous syndrome. The central nervous system disturbances in this syndrome might be secondary to developmental vascular anomalies. Therefore, the linear nevus sebaceous syndrome exhibits important similarities to the Sturge-Weber variety of neurocutaneous syndrome.- - - - - - - - - - ranking = 0.16494119298576keywords = central nervous system, nervous system (Clic here for more details about this article) |
7/34. Epileptic disorder as the first neurologic manifestation of blue rubber bleb nevus syndrome.Blue rubber bleb nevus syndrome is an uncommon neurocutaneous disorder characterized by distinctive vascular malformations on the body surface. vascular malformations of internal organs (typically the gastrointestinal tract) are also frequently present. However, malformations of the central nervous system have only rarely been described. We report a case of blue rubber bleb nevus syndrome in a 5-month-old boy with cutaneous manifestations characteristic of this process present from birth and multiple cerebral angiomas detected by magnetic resonance imaging. At age 1(1/2) months, the patient showed myoclonic seizures and complex partial seizures that were refractory to various antiepileptic regimens. At age 5 months, electroencephalograms (EEGs) showed continuous generalized slow spike-waves, predominantly in the right temporal region; however, EEGs normalized after induction of coma with intravenous midazolam. At age 13 months, the patient suffered from occasional seizures and slightly retarded psychomotor development. epilepsy is rare in this syndrome but as in other neurocutaneous syndromes (e.g., sturge-weber syndrome) can compromise psychomotor development; thus, every effort should be made to control seizures.- - - - - - - - - - ranking = 0.16494119298576keywords = central nervous system, nervous system (Clic here for more details about this article) |
8/34. sturge-weber syndrome involved frontoparietal region without facial nevus.Classic sturge-weber syndrome is characterized by a facial nevus and hamartomatous lesion in the brain. Hamartomatous lesions are usually located in the ipsilateral occipital region of the facial nevus. The other lobes may be involved. A few cases of sturge-weber syndrome without facial nevus have been reported. A 9-month-old male was admitted with the complaint of afebrile seizures two times. We observed the third seizure, which was complex partial, in the clinic. There was no facial hemangioma. On computed tomography and magnetic resonance imaging of the brain we observed findings concordant with the angioma in the right frontoparietal region, although the occipital region was intact. This patient appears to be the first with sturge-weber syndrome without facial nevus, and with involvement of the frontoparietal region but not the occipital region. We do not know the embryologic basis of this association.- - - - - - - - - - ranking = 0.020705684170828keywords = brain (Clic here for more details about this article) |
9/34. A case of unilateral, systematized linear hair follicle nevi associated with epidermal nevus-like lesions.Multiple hair follicle nevi are an extremely rare condition. In 1998, a case of unilateral multiple hair follicle nevi, ipsilateral alopecia and ipsilateral leptomeningeal angiomatosis of the brain was first reported from japan. Very recently, hair follicle nevus in a distribution following Blaschko's lines has also been reported. In this paper, we observed a congenital case of unilateral, systematized linear hair follicle nevi associated with congenital, ipsilateral, multiple plaque lesions resembling epidermal nevi but lacking leptomeningeal angiomatosis of the brain. These cases implicate the possibility of a novel neurocutaneous syndrome. Additional cases should be sought in order to determine whether this condition is pathophysiologically distinct.- - - - - - - - - - ranking = 0.020705684170828keywords = brain (Clic here for more details about this article) |
10/34. Left-sided facial nevus with contralateral leptomeningeal angiomatosis in a child with sturge-weber syndrome: case report.sturge-weber syndrome is characterized by a facial vascular nevus associated with an ipsilateral leptomeningeal angioma. Variants of this classical presentation have been described in the literature, some of which have prognostic significance. We report a magnetic resonance imaging (MRI)-confirmed variant of a leptomeningeal angioma contralateral to the facial nevus. We describe one patient with sturge-weber syndrome who presented with a left-sided facial nevus, left eye glaucoma, episodes of left-sided weakness, and right-sided leptomeningeal angiomatosis by gadolinium-enhanced brain MRI. The literature regarding variants of sturge-weber syndrome and their prognosis is reviewed. The prognosis for this variant is likely similar to sturge-weber syndrome with an ipsilateral leptomeningeal angioma.- - - - - - - - - - ranking = 0.010352842085414keywords = brain (Clic here for more details about this article) |
