Abstract  Myxopapillary ependymoma rarely presents as a primary intra-sacral lesion and extensive bony destruction is unusual. Radiological features do not help in distinction from other commoner sacral tumors, like chordoma. Hence, histopathology serves as the best diagnostic modality for this differentiation. We report the case of a 42-year-old man with a primary intra-sacral myxopapillary ependymoma causing extensive osteolysis. [ABSTRACT FROM AUTHOR]

AbstractIntroduction??Amongst the mixed glioneuronal tumours, ?papillary glioneuronal tumour?, a new variant, has been described recently.Case report??We report a case of papillary glioneuronal tumour in a 4-year-old boy who presented with fever, weakness of left upper and lower limbs and headache for the last 2.5?month. Radiologic examination showed a cystic space-occupying lesion with mural nodule in the right frontal lobe with extension into white matter. Surgical excision of a large cystic mass with small solid nodule was done. Pathological examination revealed a well-circumscribed tumour showing predominantly papillary architecture with focal aggregates of cells in sheets. The papillae were composed of hyalinised blood vessels lined by single to multi-layered cells. The tumour cells showed mild pleomorphism without any necrosis. The individual tumour cells had scant eosinophilic cytoplasm, round to oval hyperchromatic nucleus with occasional mitoses. The tumour cells were immunopositive for glial fibrillary acidic protein, synaptophysin, vimentin, and S-100 protein, but negative for neurofilament, epithelial membrane antigen, cytokeratin and CD34. MIB-1 labelling index was approximately 12% in the highest proliferating areas. In view of subtotal excision of the tumour and high MIB-1 labelling index (LI), the patient was given chemotherapy and he is doing well at 1-year follow-up.Discussion??This report supports the existence of this rare tumour. Some of its rare clinicopathological features like young age, cyst with mural nodule, presence of mitoses and raised MIB-1 LI need to be documented. [ABSTRACT FROM AUTHOR]

Abstract

The article focuses on the success of treating spinal dural arteriovenous fistulas (DAVFs) to an elderly male with the use of magnetic resonance angiography (MRA) in India. The MRI and the spinal angiography were conducted to be able to determine the cause of the gradual onset spastic parapesis with bladder symptoms. The use of MRA has been viewed efficient to rule out the occurrence of DAVFs.

Abstract  Dermoid cysts represent a rare group of tumors manifesting predominantly in adulthood. Rupture of these tumors is well described with it being symptomatic more commonly intracranially as compared to central canal rupture of intraspinally located dermoid tumor which not only is uncommon, but also frequently asymptomatic. The authors report an unusual case of asymptomatic conus dermoid in a young male diagnosed when investigated for a symptomatic isolated central canal rupture. Fatty contents within the central canal may be a harbinger of an underlying dermoid tumor and a whole spine MRI should be performed in such cases to rule out this bizarre presentation.
