[Paracoccidioidomycosis in cerebral hemisphere and brainstem: case report].

We report on a 36 years-old man that had been at the Amazon forest four years before. Six months before the admission he had developed a progressive quadriparesis, gait ataxia, dysphagia, dysarthria, difficulty in breathing and hiccup. The gadolinium-enhanced T1-weighted MRI showed a lesion into the right parietoccipital area and another into the medulla, that was the largest.

[Vertebral aneurysmatic bone cyst: study of three cases].

Aneurysmatic bone cyst is a hypervascularized, benign lesion locally destructive by its progressive growth with greater incidence in the second decade of life. It lodges preferably in the long bones and vertebrae. The clinical picture varies from pain to local edema and even neurological symptoms when in vertebral location.

[Schwannoma of brachial plexus: report of two cases].

Schwannomas, neurinomas or neurilemmomas are benign peripheral nerve tumors. The literature report some cases associated with neurofibromatosis 2. We report two cases of cervical schwannoma originating from the brachial plexus unassociated with neurofibromatosis.

[Foreign body in the orbital cone: case report].

Orbital injuries may be associated with the presence of foreign bodies in which long retention leads to damages such as loss of vision or cerebral abscess. We present the case of a 21-year-old male patient that developed ptosis, limitation of movements and an inflammatory reaction in the right eye after being hit by a tree branch. A CT scan of the orbits revealed an increased density in the right orbital cone.

[Eosinophilic granuloma of the cervical spine: case report].

Eosinophilic granuloma (EG) is a benign condition of histocytes proliferation localized or multifocal. It is presents in the cervical spine in 1.5%-20% of the cases of EG.

Contribution to the surgical treatment of patients with cervical spine cord injury using simple procedures.

Thirty-nine patients with acute cervical spine fractures and/or dislocations between C3 and C7 were submitted to an anterior approach using bone graft fixation without screw and plate systems and three required a preliminary posterior approach to reduce a dislocation. Graft dislodgement due to technical problems occurred at a rate of 7.7% postoperatively and 2.

[Tumoral form of neurocysticercosis: case report].

The authors report a case of neurocysticercosis by giant cyst (3.9 x 3.4 cm), where there were clinical manifestations of increased intracranial pressure and characteristics of image in computed tomography of cranium of expansive process with mass effect in central nervous system (CNS).
