bone cysts/癲癇性発作

Chondroblastomas are rare tumors that characteristically arise from the epiphyseal cartilage of long bones of the immature skeleton. Intracranial involvement is uncommon, though the squamous portion of the temporal bone is preferentially affected due to its cartilaginous origin. Patients with

Aneurysmal bone cyst (ABC) of the skull is exceedingly rare. We report a unique case of an intradural ABC without bone involvement presenting with raised intracranial pressure. The patient was a 14-year-old boy who presented with headache, vomiting and right focal seizure. Imaging showed a large

Seizure is a classical feature of intra axial brain parenchymal lesion. Simple bone cyst is an unusual bony pathology at skull base presenting with unexpected symptoms of complex partial seizures. Skull base neuro-endoscopy has managed such lesions more effectively with reduced post-operative

The patient, a 52-year-old male, experienced a generalized convulsive seizure. Computed tomography (CT) revealed a solitary, noncalcified cyst, 1 x 2 cm in diameter, in the left occipital lobe, without contrast enhancement. No other lesions were found in systemic soft tissues, skeletal muscles, or

We report a 9-year-old girl who presented with focal seizures, hemiparesis, headache, vomiting and bilateral optic atrophy. CT scan revealed a giant solitary cyst in the left parietal lobe. Serology and histopathology of the excised cyst confirmed the diagnosis of neurohydatidosis which is a rare

Seizures are the commonest manifestation of brain parenchymal cysticercosis. In terms of pathophysiological basis and prognostic significance of the seizures, a distinction might be applied between viable cysts, solitary cysticercus granuloma and calcific cysticerci. A number of uncertainties shroud

Encephalocraniocutaneous lipomatosis (ECCL) is a sporadically occurring neurocutaneous disorder characterized by ocular anomalies, mainly choristomas; by skin lesions consisting of hairless fatty tissue nevi (nevus psiloliparus), focal dermal hypoplasia, alopecia, and periocular skin tags; and by

Hydatid cyst of the brain is more common in children than adults. The cyst is always solitary unless the primary site is the brain. Cerebral hydatid cyst (CHCy) is most frequently supratentorial involving the territory of the middle cerebral artery, especially the parietal lobe. This study included

Congenital generalized lipodystrophy (CGL) is an autosomal recessive disorder with two major subtypes. Variants in AGPAT2 result in CGL type 1 with milder manifestations, whereas BSCL2 variants cause CGL type 2 with more severe features. Muscle hypertrophy caused by lack of adipose tissue is present

Cerebral cysticercosis is no longer an uncommon disease in areas such as Southern California to which there is extensive travel and immigration from adjoining areas in which the disease is endemic. The diagnosis of cerebral cysticercosis should be entertained in patients from such an endemic area

We present a case-report and review of the literature on membranous lipodystrophy. This is a rare disease characterized by progressive presenile dementia, multiple bone cysts with pathologic fractures, generalized cerebral seizures with abnormal EEG and bilateral calcifications of the basal ganglia.

Thrombotic thrombocytopenic purpura is an acute syndrome with abnormalities in multiple organ systems, which becomes manifest with microangiopathic hemolytic anemia and thrombocytopenia. The hereditary or acquired deficiency of ADAMTS-13 activity leads to an excess of high molecular weight von

The management of cystic supratentorial gliomas is hampered by lack of documentation of the natural history of these lesions and by a lack of evaluation of modes of surgical therapy. We analyzed these factors in 25 patients with solitary cysts operated upon over a 20-year period. Two distinctive

For the treatment of dural arteriovenous malformation (AVM), meningioma and other external carotid lesions, a method of chemical embolization using a conjugated estrogen is reported. A total of 40 cases were treated, including 11 cases of dural AVM, 20 cases of meningioma and 9 other cases such as

In the present review we report a case of a 53-year-old woman affected with a cyst solitary cerebral hemispheric lesion causing acute generalized seizure. Clinical and neuroradiologic diagnosis of cystic astrocytoma was performed and the patient was operated. Microscopic analysis of the surgical
