Review Case Reports
Hyponatremic seizure due to huge abdominal cerebrospinal fluid pseudocsyt in a child with ventriculoperitoneal shunt: a case report.
Placement of ventriculoperitoneal(VP) shunt is a worldwide accepted procedure for treatment of hydrocephalus. This procedure have various intra-abdominal complications, of which pseudocyst formation is a rare one. ⋯ To the best of our knowledge, hyponatremic seizure has not been previously reported as a presentation of abdominal CSF pseudocyst in the literature. Our case has also the largest CSF pseudocyst with respect to body surface area of the child in the literature.

Review Case Reports
Primary fourth ventricular meningioma: case report and review of the literature.
Primary fourth ventricle meningiomas are extremely rare, and they are defined as meningiomas arising from the choroid plexus and lying strictly within the fourth ventricle. In this report we present a 61-year-old man with progressive worsening vertigo and gait disturbance, and new onset of diplopia. Neurological examination revealed bilateral abducens nerve paralysis, horizontal nystagmus, and gait disturbance with truncal ataxia. ⋯ The patient was operated in the prone position with suboccipital craniotomy and splitting the lower vermis. Total resection of the tumor was achieved with no intra- or post-operative complications. Histopathologic examination revealed fibroblastic type meningioma (WHO grade I).

Review Case Reports
Total resection of inferiorly located sacral chordoma with posterior only approach: case report and review of the literature.
Chordoma is a primary sacral neoplasm of ectodermal origin and makes up %1- 4 of all primary bone tumors. It is usually present on the midline cerebrospinal axis and the most common locations are the spheno-clival region and the sacrum. ⋯ Using the retrorectal fat tissue as a cleavage line in the posterior approach guides the neurosurgeon to resect the tumor totally and reduce the hemorrhage in sacral chordomas. In this case report, we tried to discuss the advantages of using of retrorectal fat tissue as a cleavage line in sacral chordomas under the literature.

Review Case Reports
Suprasellar arachnoid cyst: a 20- year follow-up after stereotactic internal drainage: case report and review of the literature.
Approximately 9 to 15% arachnoid cysts occur in the sellar or suprasellar region. The optimal management of symptomatic suprasellar cysts continues to pose a challenge to neurosurgeons. This case report describes a patient with a suprasellar arachnoid cyst who presented at the age of 3 and was followed for 20 years after cystoventriculostomy. ⋯ During a follow-up of 20 years, signs of precocious puberty disappeared and the girl showed normal sexual development. Endocrine profiles and visual function remained normal. The stereotactic approach to suprasellar arachnoid cysts is a safe procedure in experienced hands.

Review Case Reports
Subcutaneous granuloma annulare of the scalp in childhood: a case report and review of the literature.
Granuloma annulare is a benign inflammatory skin lesion of unknown etiology that is usually seen in adults and children and subtypes of it includes localized granuloma annulare, generalized granuloma annulare, subcutaneous granuloma annulare and arcuate dermal erythema. Etiology and pathogenesis of granuloma annulare are obscure, although there is much evidence for an immunologic mechanism. Precipitating factors are insect bites, sunburn, photochemotherapy, drugs, physical trauma, acute phlebitis and sepsis after surgery. ⋯ Subcutaneous granuloma annulare of the scalp is rare lesion in childhood and nodules on the scalp are usually non-, or slightly mobile, whereas lesions on the extremities are freely mobile. For definitive diagnosis, a biopsy should be performed but wide surgical intervention or medical treatment is not indicated. In case of recurrence, no additional diagnostic studies are necessary.
