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.

Intradural extramedullary cysticercal abscess of spine.

Neurocysticercosis (NCC) is one of the most common parasitic diseases affecting the central nervous system. Typically spinal NCC involvement has a concomitant cranial involvement. Spinal involvement by NCC, either intramedullary or extramedullary is very uncommon.

Management of pediatric colloid cysts of anterior third ventricle: A review of five cases.

Object: Colloid cysts are congenital benign lesions, associated with more aggressive clinical and radiological picture in children than in adults. We present our experience in management of five pediatric patients with colloid cyst of the anterior third ventricle. They have an excellent chance of surgical cure, or they can be devastating and even fatal, if not recognized on time and treated.

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.

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.

Delayed anterior cervical plate dislodgement with pharyngeal wall perforation and oral extrusion of cervical plate screw after 8 years: A very rare complication.

We report a patient with congenital anomaly of cervical spine, who presented with clinical features suggestive of cervical compressive spondylotic myelopathy. He underwent C3 median corpectomy, graft placement, and stabilization from C2 to C4 vertebral bodies. Postoperative period was uneventful and he improved in his symptoms.

Primary spinal epidural lymphomas.

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

Management outcome of the transcallosal, transforaminal approach to colloid cysts of the anterior third ventricle: an analysis of 78 cases.

Background: Colloid cysts are not common brain lesions and account for 0.2-2.0% of all brain lesions.

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.

Malignant Course of a Metastatic Melanoma During Pregnancy: A Case Report.

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.

Supratentorial and cerebellar liponeurocytomas: report of four cases with review of literature.

Liponeurocytoma is not exclusive to the cerebellar or fourth ventricular location. Since its inclusion in the central nervous system tumor classification in 2000, six cases with similar radiological, histomorphological and immunohistochemical features have also been described in the lateral ventricles. In the present study, we report clinical, radiological and pathological findings of three supratentorial and one cerebellar liponeurocytoma from our records, evaluated with an extensive panel of immunohistochemistry, and review published cases in the literature.

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.

Invasive rhino-cerebral fungal granuloma.

Background: Increased incidence of fungal infection has been reported globally in the recent years. Fungal infection of the central nervous system remains one of the most difficult diseases to treat and requires multi-modality intensive therapeutic strategies.

Materials And Methods: Retrospective analysis of case records of patients with confirmed skull base fungal granuloma treated at a tertiary hospital between 1988-2008.

Cervical solitary long segment cystic Schwannoma.

Cystic neurofibromas are very rare and are of separate entity; occurrence in the cervical spine extending over a long segment intra-durally is very rare. There is a paucity of literature available on cervical cystic Schwannoma and its MRI characteristics. As the preoperative diagnosis of these tumors helps in planning the surgery for this rare tumor the imaging findings reported herein may aid in the preoperative diagnosis and management.

Suboccipital segment of the vertebral artery: a cadaveric study.

Objective: To study the course, relationships, branches and possible anomalies of the vertebral artery in the suboccipital region in adult Indian cadavers.

Materials And Methods: Twenty-one suboccipital segment vertebral artery specimens from embalmed, Indian adult cadavers were dissected and studied. Dissection was performed using microsurgical instruments and was carried out from the skin up to the vertebral artery in layers.

Intracranial epithelioid hemangioendothelioma.

Introduction: Epithelioid hemangioendothelioma (EHE) is an uncommon soft-tissue vascular neoplasm. Although a well-defined entity outside the neuraxis, its intracranial occurrence is rare. Literature review revealed 35 reported cases till date.

Exophytic choroid plexus papilloma of the fourth ventricle presenting with cerebrospinal fluid rhinorrhea: a case report.

Background: Choroid plexus papillomas are rare benign neoplasms that arise from the ventricular choroid plexus and are considered to be of ependymal origin. They are slow-growing lesions, are commonly associated with hydrocephalus, and are prone to hemorrhage spontaneously. Most of them are located in the posterior fossa in adults, the fourth ventricle being the most common location.

Surgical management of brainstem hydatid cyst--an unusual site.

Background: The authors describe their surgical experience of a hydatid cyst in the brainstem, which is an unusual site. The cyst was internally decompressed and totally excised. Although the Dowling technique has been described to be the ideal method for removal of hydatid cysts, it may not be possible when the cyst is in a deep-seated, vital, and eloquent location.
