Gliosarcoma With Cartilage Formation

A case of gliosarcoma with cartilaginous component is described. Immunohistochemical and electron microscopic studies confirmed the presence of glial and fibroblastic elements. A major part of the sarcomatous tissue was undifferentiated and not labeled by any of the markers used including those for endothelial cells. The cartilage cells also were not labeled either by antiglial fibrillary acidic protein or any other marker. The occurrence and histogenesis of cartilage in gliomas and gliosarcomas have been reviewed.

Intramedullary spinal cysticercosis. Case report and review of literature.

Intramedullary spinal cysticercosis is extremely uncommon; only 29 cases have been reported previously. A case of solitary intramedullary spinal cysticercosis is described. Factors accounting for the rarity of intramedullary cysticerci are reviewed and the probability of reaching a preoperative diagnosis is discussed. This is the fifth such case reported from India.

Congenital intramedullary spinal ependymal cyst

A rare case of congenital intramedullary ependymal cyst of the dorsal cord in a 7-year-old boy associated with kyphoscoliosis and rachidian malformations of the dorsal spine is reported. Myelography suggested an intramedullary lesion. The posterior location and presence of a clear plane of cleavage from the medullary tissue enabled total enucleation of the cyst. Histological differentiation from other similar intradural cysts is discussed and the relevant literature is reviewed. This is the fifth such case reported in the literature.

Actinomycotic brain abscess

A histologically confirmed actinomycotic brain abscess, in a previously healthy female, is reported. CT scan findings of a thick walled multiloculated ring enhancement with smooth inner margin and irregular nodular enhancement of outer margin, along with contiguous patchy enhancing lesion with circular low attenuation areas were suggestive of a chronic granulomatous abscess. Surgical excision and prolonged antibiotic therapy produced a good resolution.

Hemibase syndrome: An unusual presentation of intracranial paraganglioma

A case of paraganglioma of parasellar origin in a 7-year-old girl is described. She presented with hemibase syndrome with involvement of a majority of the left cranial nerves. Three times in the past 2 years she had recurrent ophthalmoplegia with complete recovery. She was treated surgically and with postoperative radiotherapy. The site of origin of this paraganglioma as well as the clinical presentation are uncommon features in this case.

Intradural extramedullary tuberculous spinal mas

Summary Four cases of intradural extramedullary tuberculous spinal granulomas without bony involvement are presented. Both, the rarity of the disease, as well as the successful microsurgical resection with good recovery prompted this report. The pathogenesis with the controversies therein, is discussed and pertinent literature is reviewed.

Primary spinal epidural Ewing's sarcoma.

A rare case of Ewings sarcoma, originating primarily in the spinal epidural space is reported. Only five similar case reports are available in the English literature. Full recovery from a state of complete paraplegia, due to malignant compression, local recurrence without distant metastases and the longest survival of more than three years and six months, makes a unique combination. Pathology and therapy are briefly discussed and the pertinent literature reviewed.

Solitary osteochondroma of spine causing spinal cord compression

Three cases of spinal cord compression due to solitary osteochondroma of the spine are reported. The rarity and benign nature of the tumour is stressed. Other reported cases are reviewed.

Cystic intracerebellar epidermoids with rim enhancement. A case report.

A case of two infected cystic epidermoids of the right cerebellar hemisphere is reported. One of the cysts showed peripheral contrast enhancement on CT. Relevant literature regarding the pathogenesis and CT diagnosis is reviewed.
