RESUMO
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.

Syringomyelia is condition in which a cyst or cavity forms inside the spinal cavity. Its management always remains a difficult. A variety of surgical techniques have been used in management of syringomyelia. Syringosubarachnoid shunt remains an effective method in management of syringomyelia. Shunt tube obstruction remains an important complication of shunt procedure. We describe a novel technique of use of polytetrafluoroethylene sponge shunt for syringosubarachnoid shunt in patient with large syrinx and Chiari 1 malformation. Polytetrafluoroethylene sponge is a non irritant material with multiple porosities that is less susceptible to blockages or kinking. It could provide a good alternative technique in syringosubarachnoid shunting.

Teratocarcinosarcoma (TCS), an aggressive and extremely rare neoplasm, usually presents as a nasal or paranasal mass. TCS can have intracranial or dural extension from a nasal mass. We found only two instances in the literature that described this lesion as primarily manifesting as an intracranial mass while arising from a primary nasal focus. We describe a patient who had a predominantly frontal-lobe TCS without any symptoms of a primary nasal mass. The gross surgical appearance was a glistening, slimy, firm white mucoid lesion, in contrast to the friable, necrotic and tan-colored lesion usually described. We report a patient with a rare intracranial TCS, and focus on the differential diagnoses of intracranial tumors. Neuropathologists and neurosurgeons should be aware of this mode of presentation for an accurate diagnosis and a well-targeted therapeutic approach.
