Objective: Deliberate C2 nerve root sectioning and its preservation have been described during posterior fusion for atlantoaxial dislocation (AAD). However, the associated outcomes have been less studied, especially in congenital AAD. Our objective was to study the clinical outcomes after C2 nerve root sectioning and the feasibility of C2 preservation in these patients.

Twenty four year male presented with somnolence and soft tissue swelling of occipital region following road traffic accident. CT scan revealed bilateral posterior fossa with bilateral temporo-occipital Extradural Hematoma (EDH) with mass effect.

This needs to be differentiated form the commonly seen calcification. We describe a rare case of osteobalstic meningioma in which bony trabeculae were seen within meningothelial cells.

Methods: Seven patients with sub-acute/chronic EDH (six supratentorial and one infratentorial) presented to us 3 to 7 days after low-velocity road traffic accidents with complaints of headache and lethargy.
Purpose: The commonly described congenital atlanto-axial dislocation and Basilar-Invagination is antero-posterior or rotational or vertical plane. However, congenital dislocation in lateral plane has received scant attention. The purpose of this manuscript is to describe this unusual entity and discuss its management.
View Article and Find Full Text PDFPurpose: Certain abnormal contact points, appearing like additional joints (pseudofacets) were observed between atlas and axis in a subset of patients with congenital atlantoaxial dislocation (CAAD). The origin, function and bearing on management of such pseudofacets remain largely undetermined. The object is to study 'pseudofacets'or 'accessory joints' in patients with CAAD and to analyze the possible genesis, role and bearing of these on surgery and fusion rates.

Olfactory region schwannomas are rare, but when they occur, they commonly arise from the meningeal branches of the trigeminal nerve and may present without involvement of the olfaction. A 24 year old lady presented with hemifacial paraesthesias. Radiology revealed a large olfactory region enhancing lesion.

Case Description: We present a case of ruptured venous aneurysm that presented with subarachnoid hemorrhage (SAH) and intraventricular hemorrhage (IVH).
Object: Stabilization of the craniovertebral junction (CVJ) by using lateral masses requires extensive dissection. The vertebral artery (VA) is commonly anomalous in patients with congenital CVJ anomaly. Such a vessel is likely to be injured during dissection or screw placement.

Study Design: Case report.
Objective: To describe a symptomatic patient with bilateral posterior accessory C1-C2 joints and their differences from the true synovial joints.
Summary Of Background Data: Accessory joints between C1-C2 are rarely described.
Ependymomas and tuberculomas are common paediatric posterior fossa lesions in developing countries and may be confused with each other due to some overlapping features. The distinction is important as the treatment for each is entirely different. We have described three young children in whom clinical-radiological features and the lipid peak seen on MR spectroscopy suggested the diagnosis of posterior fossa tuberculomas.
