Aneurysmal bone cyst of the lumbar spine.

An aneurysmal bone cyst (ABC) is a benign, locally proliferative vascular disorder of non-neoplastic osseous lesions in children and young adults. Seventy-five percent of ABCs occur before the age of 20 years. They comprise 1.

Complication avoidance in transcallosal transforaminal approach to colloid cysts of the anterior third ventriclen: An analysis of 80 cases.

Object: The objective of the present study is to analyze the complications and their avoidance in a series of 80 patients operated by transcallosal transforaminal approach to colloid cysts of the anterior third ventricle.

Materials And Methods: The surgical outcome and complications of 80 patients operated by transcallosal transforaminal approach for colloid cysts in the anterior third ventricle was analyzed. A detailed pre- and post-operative neurological assessment was done in all patients.

Isolated skull base primary Ewing's sarcoma: an extremely rare location.

A 16-year-old boy presented with history of headache and blurring of distant vision. He had UMN facial paresis and papilledema. Imaging revealed a heterogenous space occupying lesion in the middle cranial fossa base with mass effect and midline shift and non homogenous contrast enhancement with erosion of the petrous bone.

Primary intrasellar schwannoma.

Intracranial schwannomas commonly arise from the eighth cranial nerve in the cerebellopontine angle. Schwannoma arising in the sella and extending into the suprasellar region is very rare and is easily mistaken for pituitary adenoma. To our knowledge, there have been only 12 previous reports.

Pediatric multifocal glioblastoma multiforme with fulminant course.

Glioblastoma multiforme (GBM) is the most common primary malignant brain tumor. GBM in children is less common than in adults and has a better prognosis. Pediatric GBM is a rare entity, and a multifocal development in a pediatric GBM is much rarer.

Primary spinal intradural extramedullary lymphoma causing cauda equina syndrome.

We report a case of lumbar intradural extramedullary lesion in an 11-year-old boy who presented with cauda equina syndrome and acute bladder disturbance. He underwent emergency surgical resection of the lesion, which was proved to be a lymphoma by histopathology and immunohistochemistry. He has improved neurologically and after 1 year, he is leading a normal life with near normal neurological functions.

Orbitotemporal neurofibromatosis: case report.

Plexiform neurofibromas occur in about 60% of neurofibromatosis type 1(NF-1) patients and can lead to severe morbidity by disfigurement or compression of vital structures. Moreover, these tumors can undergo malignant transformation. Both focal and localized bone abnormalities are part of the phenotypic expression of NF-1.

Primary spinal epidural lymphomas.

An epidural location for lymphoma is observed in 0.1-6.5% of all the lymphomas.

Multiple burr hole surgery as a treatment modality for pediatric moyamoya disease.

Objective: To re-emphasize that indirect revascularization surgery alone, where multiple burr holes and arachnoid openings are made over both cerebral hemispheres, is beneficial in the treatment of moyamoya disease (MMD) in children.

Clinical Presentation: We report a 10-year-old boy who presented with complaints of episodic headache for the last 5 years. At the peak of his headache he had visual disturbances and acute onset weakness of left-sided limbs, recovering within a few minutes.

Cutaneous melanoma can metastasize to any organ, including brain and spinal cord. A 27-year-old lady, four months after conception presented with generalized seizures and was diagnosed to have subarachnoid hemorrhage. Further investigation did not reveal aneurysm.

Intracranial Rosai Dorfman Disease: report of three cases and literature review.

Background: Rosai-Dorfman Disease (RDD) is a rare idiopathic non-neoplastic histioproliferative disease characterized clinically by massive painless cervical lymphadenopathy, fever and weight loss. Extranodal involvement has also been recognized. Central nervous system (CNS) manifestations are extremely rare and patients with intracranial involvement usually present with clinical and radiological findings suggestive of a meningioma.
