Anterior Communicating Artery Aneurysms: Surgical Strategy and Outcome based on Proposed Newer Classification.

Background: The ruptured anterior communicating artery aneurysm is the most frequent intra-cranial aneurysm treated at any neurosurgical department. These aneurysms arise from either the A1-A2-Acom artery junction or Acom artery. The surgical outcome depends on the age of the patient, time duration between ictus and surgery, and Hunt and Hess grade at admission.

Postoperative Tinnitus after Vestibular Schwannoma Surgery: A Neglected Entity.

Background: This prospective study analyzes the factors responsible for pre and postoperative persistent tinnitus following vestibular schwannoma (VS) surgery and discusses the possible etiopathogenetic mechanisms.

Materials And Methods: Sixty-seven consecutive patients with unilateral VS operated via the retrosigmoid-suboccipital approach were included in the study. The Cochlear nerve, often unidentifiable from the tumor capsule, was resected during the surgery.

Meningioma in a Postrenal Transplant Case: More than Meets the Eye.

Background: Patients with a renal transplant are an ever-increasing demographic. Their life expectancy is also on the rise and thus malignancies or tumors in these cases are more frequent. These patients are often on immunosuppressive drugs that are known to cause changes in the microvasculature, especially of the deep white matter.

Adult Versus Pediatric Tethered Cord Syndrome: Clinicoradiological Differences and its Management.

Background: Dysraphic lesions in adults, presenting clinically as tethered cord syndrome (TCS), are relatively rare, and their optimal management remains controversial.

Patients And Methods: We performed a retrospective analysis of our pediatric database over a period of last 7 years to focus on the adult TCS. Our aim was to determine the clinicoradiological and etiopathological differences between adult and pediatric patients as well as to determine the results of surgery in adult TCS.

Results of Proactive Surgical Clipping in Poor-Grade Aneurysmal Subarachnoid Hemorrhage: Pattern of Recovery and Predictors of Outcome.

Background: The outcome associated with the treatment of poor-grade aneurysmal subarachnoid hemorrhage is rather discouraging. Even then, some patients may survive; however, the long-term outcomes and the patterns of recovery of these survivors have not received much attention in the literature.

Methods: A total of 85 patients (mean age 53.

Factors Leading to Oro-Facial Herpetic Eruptions in Patients Undergoing Surgery for Vestibular Schwannoma.

Objective: To study factors influencing oro-facial herpetic eruptions (HEs) in patients undergoing retromastoid suboccipital craniectomy for vestibular schwannomas (VS).

Methods: A retrospective analysis of the prospectively collected database (from July 2014 to December 2015). A total of 87 patients underwent retromastoid suboccipital craniectomy for VS at our center.

Serial MR Imaging in Suprasellar Xanthogranuloma: Growth Pattern and New Lesions.

Xanthogranuloma is a rare lesion of the sellar-suprasellar region. We describe a case of suprasellar xanthogranuloma in whom serial MRI revealed features that have not been previously described--development of dural tail, vascular encasement and intra-axial lesions in posterior fossa.

Nerve sheath myxoma (neurothekeoma) of cerebellopontine angle: case report of a rare tumor with brief review of literature.

Nerve sheath myxoma (neurothekeoma) are rare benign nerve sheath tumors, usually arising in the skin of the head and neck region and upper extremities in young females. To the best of author's knowledge only two cases of intracranial neurothekeoma have been published in the English literature. These tumors were located in the parasellar area and in middle cranial fossa.

Cytomorphology of intraparenchymal mesenchymal chondrosarcoma in frontal lobe: report of a case.

lntracranial mesenchymal chondrosarcomas (MC) and especially those that originate in brain parenchyma, are rare. A diagnosis of MC can be challenging to make on squash cytology. We describe cytomoprhology of solid cystic extraskeletal intraparenchymal MC in a 22-year-old male.

Extramedullary hemopoiesis with undiagnosed, early myelofibrosis causing spastic compressive myelopathy: Case report and review.

Extramedullary hemopoiesis (EMH) is a common compensatory phenomenon associated with chronic hemolytic anemia. Abnormal hemopoietic tissue usually develops in sites responsible for fetal hemopoiesis, such as spleen, liver and kidney; however, other regions such as the spine may also become involved. In this study, a patient presenting with spastic paraparesis due to EMH in the dorsal spine is described.

Congenital irreducible atlantoaxial dislocation associated with cervical intramedullary astrocytoma causing progressive spastic quadriparesis.

Simultaneous presence of congenital irreducible atlantoaxial dislocation (AAD) and cervical intramedullary astrocytoma has not been previously described and may cause disabling myelopathy. This 55-year-old lady presented with suboccipital pain, spastic quadriparesis, Lhermitte's phenomenon and sphincteric disturbances. Lateral radiographs and magnetic resonance imaging showed irreducible AAD, occipitalized atlas, C2-3 fusion, and,an intramedullary tumor from C2-5 level iso-to-hypointense, non-enhancing, except in a small segment in the dorsal C2 level.

Occipitocervical contoured rod stabilization: does it still have a role amidst the modern stabilization techniques?

Background: The occipitocervical contoured rod (CR) stabilization for use in craniovertebral junction (CVJ) pathologies is an effective and economical technique of posterior fusion (PF).

Aims: The various indications for CR in CVJ pathologies are discussed.

Settings And Design: Retrospective analysis.

Pediatric congenital atlantoaxial dislocation: differences between the irreducible and reducible varieties.

Object: Clinicoradiological differences and outcome following surgery in pediatric patients (< or = 16 years of age) with congenital irreducible atlantoaxial dislocation (IAAD) and reducible atlantoaxial dislocation (RAAD) were analyzed.

Methods: Ninety-six patients (57 with IAAD and 39 with RAAD) were categorized as follows: Grade I, no deficits except hyperreflexia or neck pain (six patients); Grade II, minor deficits but independent for activities of daily living (25); Grade III, partially dependent (30); and Grade IV, totally dependent (35). Patients with RAAD underwent direct posterior fusion, and those with IAAD were treated with transoral decompression and posterior fusion.
