RESUMO
A 9-month-old male child was brought with complaints of increasing head size for 2 months, increasing lethargy and vomiting for the last 2 days. Radiology revealed a heterogeneously enhancing, globular lesion in the pineal region with hydrocephalus. Near total excision of the tumor was carried out. The histopathological examination of the lesion showed heterogenous elements in the form of mature neuroepithelial and ectomesenchymal tissue. The pathology and radiology of this unusual lesion is discussed with relevant review of literature.

Herein, we report on an inferior migration of an intervertebral disc C6-7 to the cervicothoracic junction manifesting as acute paraplegia. The patient showed a remarkable recovery after the surgery. The diagnostic dilemma and management difficulties of such an entity are briefly discussed.

We present an interesting case of conus medullaris cavernoma that was initially treated as transverse myelitis. Haemorrhagic lumbar puncture led us to perform magnetic resonance (MR) imaging, which showed the presence of a cavernous angioma at the D12-L1 level. The total excision of the lesion was followed by dramatic improvement. We suggest that MR imaging be performed early in all suspected cases of transverse myelitis so that emergency surgical intervention can be offered before the development of permanent neurological deficits.

Pure ventral midline giant schwannoma is an extremely rare entity. Spinal intradural extramedullary schwannomas commonly occur posterolateral or anterolateral to the spinal cord. A case of a pure midline ventrally situated giant pan cervical extramedullary schwannoma in an 18-year-old male patient with compressive myelopathy and sphincter involvement is presented. Spinal MR imaging showed a midline ventrally situated extramedullary tumor with severe spinal cord compression extending from clivus to C7 vertebra. It was resected through a posterolateral approach. Histology was consistent with a schwannoma. Post operative MR imaging showed no evidence of the tumor. The radiological features, pathogenesis and surgical strategies in management of these difficult tumors are discussed and the relevant literature is briefly reviewed.
