A mucocele of a para-nasal sinus is an accumulation of mucoid secretion and desqua-mated epithelium within the sinus with distension of its walls and is regarded as a cyst like expansile and destructive lesion. If the cyst invades the adjacent orbit and continues to expand within the orbital cavity, the mass may mimic the behavior of many benign growths primary in the orbit. The frontal sinus is most commonly involved, whereas sphenoid, ethmoid, and maxillary mucoceles are rare. Floor of frontal sinus is shared with the superior orbital wall which explains the early displacement of orbit in enlarging frontal mucoceles. Frontal sinus mucoceles are prone to recurrences if not managed adequately. Here, we are evaluating different approaches used to manage various stages of frontal mucoceles which presented to us with orbital complications. Three cases of frontal sinus mucocele are discussed which presented to our OPD with different clinical symptoms and all cases were managed by different surgical approaches according to their severity. We also concluded that it is prudent to collaborate with the neurosurgeons for adequate management of such complex mucoceles by a craniotomy approach.

Pediatric glioblastomas are associated with longer progression-free as well as overall survivals. Extent of tumor resection is the strongest predictor of survival in pediatric glioblastoma. Hence, an aggressive surgical resection may fetch a better outcome in children with glioblastoma.

Object Intracranial aneurysms are extremely uncommon in the pediatric population, their characteristics are not well studied, and certain features make them unique. The authors analyzed pediatric patients with aneurysms to try to understand their clinical, radiological, and outcome profile. Methods Sixty-three pediatric patients (≤ 18 years of age) with ages ranging from 4 to 18 years and features (clinical and radiological) suggestive of aneurysm presented to, and were treated at, the authors' center in the past 20 years (1991–2011). Included in the present study were only those patients who underwent surgical intervention, and thus data for 57 patients were analyzed. Results Seventy-three aneurysms in 57 patients were surgically treated. There was a slight female predominance (M/F 1:1.2), and the mean age among all patients was 12.69 ± 3.75 years. Fifty patients (87.72%) presented with subarachnoid hemorrhage, 4 (7.02%) with mass effect, and 3 (5.26%) with seizure. On presentation the majority of patients (45 [78.95%]) had a good clinical grade. Eleven patients had multiple aneurysms. The internal carotid artery (ICA) bifurcation was the most common aneurysm site (18 cases [24.66%]), followed by the middle cerebral artery (MCA) bifurcation (11 cases [15.07%]). At a mean follow-up of 18.58 ± 10.71 months (range 1.5–44 months), 44 patients (77.19%) had a favorable outcome, and 5 patients had died. Conclusions Pediatric patients with intracranial aneurysms most commonly presented with subarachnoid hemorrhage, and there was a slight female predominance. The ICA bifurcation followed by the MCA bifurcation was the most common aneurysm site. The incidence of posterior circulation and giant aneurysms is higher in pediatric patients than in the adult population. Children tend to present with better clinical grades and have better overall survival results and good functional outcomes.

Background:Gliosarcoma (GS), a subtype of glioblastoma (GBM), is a rare primary neoplasm of the central nervous system. Certain features like temporal lobe affinity, tendency for extraneural metastasis and poorer outcome compared to GBM indicate that GS may indeed be a separate clinicopathologic entity. This led us to revisit this entity in our settings.Materials and Methods:Between 2009 and 2014, 16 cases of histologically proven GSs (14 primary, two secondary) were treated. Patient data were retrieved retrospectively. Statistical analysis was performed with? Statistical Package for Social Sciences, version 17.0. (Chicago, Illinois, USA). Survival was analyzed by Kaplan–Meier method.Results:GS predominantly affected males in their fifth decade of life. Raised intracranial pressure was the most common mode of clinical presentation. Temporal lobe was the most commonly affected part of the brain and majority of primary and all of secondary GBM were located peripherally. In 7 (43.8%) patients, tumor was radiologically well-demarcated and enhanced strongly and homogenously on contrast as compared to 9 (56.2%) patients where the tumor was ill-defined and showed heterogenous patchy or ring enhancement. Extent of excision was total in seven patients (43.8%), near total in 4 (25%) and subtotal in five patients (31.2%). Median survival was 6 months. Patients with well-demarcated, enhancing mass on imaging intraoperatively had firm tumors with a good plane of cleavage and had a better survival (8 months) compared to those in whom the tumor radiologically and intraoperatively mimicked GBM (2 months).Conclusion:GS is associated with poor survival (median survival 6 months). Radiological and intraoperative findings help categorize these tumors into GBM like GS and meningioma like GS. While the former histologically mimics GBM and has very poor survival (2 months), GS with meningioma like feature tends to have better survival (8 months).

Primary melanocytic tumors of the central nervous system (CNS) are uncommon lesions. These lesions arise from the melanocytes located within leptomeninges and include diffuse melanocytosis and meningeal melanomatosis (seen in neurocutaneous melanosis), melanocytoma, and malignant melanoma. To study, the clinical course, neuroradiological features, morphology and immunohistochemistry of primary melanocytic tumor of CNS. Demographic, clinical and surgico-pathologic findings of five patients with melanocytic tumors seen between 1996 and 2003 were studied. In this study, five cases of primary melanocytic tumors have been reported: four cases of malignant melanoma and one case of melanocytoma. Three of the 5 cases were intracranial and 2 were spinal. The mean age in the present study was 26 years. Presenting features varied according to the location. Primary melanocytic tumor of CNS are rare. Whenever possible, complete surgical excision is the best treatment.
