A patient with Sturge-Weber syndrome without the characteristic facial nevus presented with focal seizures which were difficult to control and borderline mental level. CT disclosed calcification in the right occipital zone. A marked decrease of the regional cerebral blood flow that extended beyond the abnormalities depicted on CT was seen by SPECT. Venous magnetic resonance (MR) angiography revealed reduction of the superficial cortical veins and prominent deep collateral venous system in the same side of the cerebral lesion. Cranial MR imaging with Gd-DTPA demonstrated the pial angioma.

The epidermal nevus syndrome (ENS) is an unusual neurocutaneous disorder consisting of the combination of an epidermal nevus and a central nervous system (CNS), ophthalmological, and/or skeletal abnormality. The study reports four new patients with ENS. Each had a confirmatory biopsy of the epidermal nevus, abnormal neurological examination findings, and documented CNS anatomical studies by imaging or autopsy. The paper also reviews the literature in English to determine neurological abnormalities found in skin-biopsy-proven cases of ENS. Hemi-atrophy, hemimegalencephaly, migrational abnormalities and vascular anomalies were found to be the most frequent intracranial abnormalities associated with ENS. Seizures and/or disabling moderate to severe developmental delays were present in a majority of patients. Seizure onset during the neonatal period or early infancy was associated with major hemispheric malformations. Neuroectodermal-derived ocular lesions were often bilateral. No consistent relation between laterality of the nevus and laterality of CNS abnormalities was found, supporting the gene mosaicism theory of pathogenesis.

We report the case of a 39-year-old para-4 gravida-4 who received polychemotherapy 5-fluorouracil 600 mg/m2, cyclophosphamide 600 mg/m2 and epirubicin 50 mg/m2 for invasive breast cancer (pT2N2Mo) with extensive metastatic involvement of all 23 axillary lymph nodes removed at 29 gestational weeks. Soon after the second course of chemotherapy at 35 weeks, she developed two eclamptic tonic-clonic seizures which were treated by antihypertensive and anticonvulsive drugs and delivery of a healthy infant, 1650 g (< 10th percentile) by cesarean section. That this patient indeed suffered from eclampsia was supported by the findings of transient postpartum severe hypertension (peak 170/110 mmHg), proteinuria (peak 3.2 g/24 h), incomplete features of the HELLP syndrome (thrombocytopenia 81,000/mm3, haptoglobin < 10 mg/dl) and of DIC, and by the results of cerebral CT scanning showing two 1-cm ischemic lesions. Since the detrimental effect of antineoplastic agents on the rapidly proliferating trophoblast is well known and as abnormal placental function, such as in triploidy, trisomy or hydatiform mole, has been associated with an increased risk for preeclampsia/eclampsia, a possible causal relationship between polychemotherapy and the subsequent development of this rare disorder is suggested.

A 9-year-old girl was diagnosed as having a linear sebaceous nevus syndrome (LSNS). The nevus sebaceus was located on the face, and the girl also had nevoid hypertrichosis on the neck, sensorineural deafness, partial anodontia, blocked tear ducts, labiopalatoschisis, and an area of micropolygyria in the left encephalic (cerebral) hemisphere. Electroencephalographic alterations were detected, but they were not accompanied by a history of seizures; furthermore, the child was not mentally retarded. This phenotypic pattern of LSNS is unusual for the rarity of associated abnormalities.

A term male neonate had an uncommon congenital vascular disorder of the skin covering the whole body and extremities. These skin lesions were characterized by mottling and persistent telangiectasia. A skin biopsy showed nevus vascularis reticularis which was recognized as cutis marmorata telangiectatica congenita. In addition to the cutaneous involvement, the patient also had fetal ascites, pleural effusion, patent ductus arteriosus, glaucoma, retinal detachment in the left eye, and telangiectasia in the right eye. Neonatal focal seizure developed and expired on the 34th day of life. The cerebral image studies suggested vascular anomalies with secondary cerebral parenchymal damage. Cutis marmorata telangiectatica congenita may be solitary but is frequently associated with other developmental defects. However, the specific findings of cerebral and ophthalmic lesions in our case were rather unusual.

The "CHIME" syndrome (MIM#280000) is a rare neuroectodermal disorder comprised of Colobomas of the eye, Heart defects, Ichthyosiform dermatosis, Mental retardation, and Ear defects. We report on the sixth child with this syndrome and the first of these to develop acute lymphoblastic leukemia at age 4 1/2 years. Her major problems included a migratory ichthyosiform dermatosis, multiple skin infections and infestations, bilateral retinal coloboma, developmental delay, seizures, infantile macrosomia, facial anomalies, a duplicated renal collecting system, and conductive hearing loss. Histologic examination of the skin demonstrated findings of an epidermal nevus with deep rete pegs, hyperkeratosis, and a markedly increased granular layer. The cause of the CHIME syndrome is unknown, but the disorder is easily recognized because of the striking phenotype. The diagnosis is important to make because of the potential for associated congenital heart disease, neurologic compromise, possible autosomal recessive inheritance, and possible association with malignancy.

We present two patients with unilateral occipital gyriform calcification and seizures. Gyriform or serpentine calcification as revealed by computed tomography (CT) scan is rare and is a characteristic finding of Sturge-Weber syndrome (SWS) and celiac disease (CD). These patients had neither the facial nevus flammeus or neurological deficits characteristic of SWS, nor the gastrointestinal symptoms characteristic of CD. CD is often accompanied by cerebral occipital calcification indistinguishable from that of SWS. We demonstrate the presence of cerebral leptomeningeal angiomatosis (LA) by Gadolinium-DTPA-enhanced magnetic resonance imaging (MRI) but could not detect LA by either CT scanning or angiography. It has been reported that contrast-enhanced MRI is useful to detect LA in SWS. However, we found no reports of enhanced MRI in patients with SWS without facial angioma. If future studies can demonstrate the absence of cortical enhancement by contrast-enhanced MRI in CD with cerebral calcifications, enhanced MRI would become an important tool for differentiating CD from SWS.

A rare case of histology-proved giant congenital melanocytic nevus (GCMN) with symptomatic leptomeningeal melanocytosis is reported. A 26-year-old man had had a large patch of pigmented nevus over his back and left arm since birth. He had begun to have seizures as well as symptoms and signs of increased intracranial pressure about six months before admission. Serial computed tomography of brain showed hydrocephalus, diffuse leptomeningeal enhancement and multiple well-enhanced, rapid-growing nodules on the surface of the cerebellum and left parietal lobe. Magnetic resonance imaging (MRI) revealed T1 shortening of leptomeninges on precontrast T1 weighted imaging. Skin biopsy was done twice and showed intradermal nevus. Biopsy on one of the intracranial nodules revealed malignant melanoma arising in the melanocytosis. He died one year after the onset of neurologic symptoms. For early diagnosis of neurocutaneous melanocytosis, we suggest 1) MRI, and 2) leptomeningeal biopsy in patients with suspected leptomeningeal malignant melanoma.

Cerebral metabolites of a patient with linear nevus sebaceus syndrome and hemimegalencephaly were determined at 18 and 30 months of age by localized proton magnetic resonance spectroscopy. Clinically, the patient suffered from hemiparesis and epileptic seizures. At 18 months of age, spectroscopy of the enlarged hemisphere revealed decreased N-acetylaspartate mainly in parietal white matter relative to the unaffected hemisphere. One year later, white matter studies indicated both reduced N-acetylaspartate and elevated myoinositol. In insular gray matter the previously normal concentrations of creatine, choline-containing compounds, myoinositol, and glutamine were increased. The findings are consistent with mild neuroaxonal loss or damage (white matter) and glial proliferation (cortical gray and white matter) of the affected hemisphere. The metabolic disturbances indicate disease progression but are less pronounced than in older patients with hemimegalencephaly.

Sturge-Weber syndrome (SWS) is a neurocutaneous syndrome characterized by a facial nevus flammeus associated with seizures, developmental delay, and, often, with hemiparesis and hemianopia. On MRI, the most characteristic finding has been reported to be leptomeningeal enhancement, believed to represent leakage of contrast medium through the anomalous pial vessels that characterize the disease. We present a case of SWS with no evidence of leptomeningeal enhancement. This case illustrates that leptomeningeal enhancement need not be present in SWS, and the absence of this characteristic finding does not preclude the diagnosis.
