choristoma/seizures

Neuroimaging studies have demonstrated that heterotopic tissue of patients with "double cortex" is activated during motor and somatosensory tasks. Activation in patients with malformations of cortical development (MCD) has been variable, likely due to the heterogeneity of the disorder. We examined

The authors describe the association of epibulbar choristomas with linear cutaneous nevi of the epidermal and sebaceous variety in 24 cases reported in the literature. The choristomas are of the bilateral, extensive, multiple and complex type. The associated ocular and systemic findings include lid

Linear nevus sebaceous syndrome (LNSS) is characterized by nevus sebaceous, mental retardation, seizures, and ocular abnormalities such as complex limbal choistoma. A young male with history of mass in right eye and blackish discoloration of skin over right and left side of forehead since birth

BACKGROUND Intracranial extracerebral neuroglial choristoma is a very rare entity. A cleft palate or a nasopharyngeal teratoma has been described as accompanying choristoma, but there are no observations of both anomalies being simultaneously present and combined. METHODS An 8-month-old girl

OBJECTIVE This study aimed to describe the clinical and histopathologic findings in four patients with complex limbal choristomas associated with linear nevus sebaceous syndrome (LNSS), a rare disorder including nevus sebaceous, seizures, and mental retardation, and often accompanied by ocular

We report of 16 year old twinsisters with a neuronal migration disorder, twin I with mental retardation and focal epileptic seizures on MRI showed general pachygyria, laminar subcortical heterotopia and mildly dilated lateral ventricles, whereas twin II whose first symptom was a cerebral seizure

We report 2 cases of an unusual central nervous system lesion involving the gyrus rectus and characterized by well-differentiated epithelial and mesenchymal components. One patient was a 30-year-old woman, and the other was a 42-year-old man. Both presented with seizures. Radiologically, the lesions

BACKGROUND Encephalocraniocutaneous lipomatosis (ECCL), also known as Haberland's Syndrome, is a sporadically occurring neurocutaneous syndrome with no gender or race predilection. ECCL patients present with a broad spectrum of clinical manifestations, often in a unilateral distribution. The

An isolated, well-differentiated ectopic cerebellum arising outside the posterior fossa is extremely rare. We present a unique case of ectopic cerebellum in 25-year-old woman with hypertelorism, skull deformation, and a longstanding history of epileptic seizures. Magnetic resonance imaging revealed

Four examples of grossly mineralized lesions of the brain, causing seizures, are described; they include 2 hamartomas, a choristoma (novel associations), and an idiopathic "brain stone." Each was detectable with routine roentgenograms, and the seizures were ameliorated by surgical therapy.

OBJECTIVE Periventricular nodular heterotopia (PVNH) is a malformation of cortical development due to impaired neuronal migration resulting in the formation of nodular masses of neurons and glial cells in close proximity to the ventricular walls. We report the clinical characteristics of the largest

OBJECTIVE To describe neoplasms diagnosed in children
