RESUMO
The meningocele and encephalocele are extracranial herniation of single meninges or meninges with brain tissue, through cranial defect. This pathology can be classificated according to contain or localization. The trans-etmoidal encephalocele is the 5% of meningoencephaloceles, and they are the 8-19% of all neural tube dysraphism. We report a 54 year-old woman with a spontaneous rhinorrhea due to an trans-ethmoidal meningocele associate with a recurrent meningitis. The computed tomographic (CT) revealed a trans-ethmoidal meningocele and she was treated with surgery. In presence of a patient with recurrent meningitis is necessary value the possibility of rhinorrhea, and an exhausted radiology study will be fulfill for identify the opening in the skull through leak CSF, and offer the best treatment. The transetmoidal can be a cause of rhinorrhea. The CT scan study of anterior fosa is a good method for diagnostic of this pathology, however, the IRM is the election method.

We report a case of MFH of the mandible in a 16-year-old girl. The mandible is a rare location of MFH of bone, with only 21 cases described in the literature. Clinical, pathologic, and radiologic features are discussed, with special emphasis on the unusual pathologic and radiographic features.

Amyloidomas involving bone are rare. The 67-year-old man reported here had a large amyloidoma of the left frontal, parietal, sphenoid (greater wing) and temporal bones causing neural compression. Plain radiographs CT and MRI are shown.

The authors report a case of chondroblastoma in the unusual location of the temporal bone. CT findings do not differ dramatically from other reports: the lesion appeared as a soft-tissue density mass in the right temporal bone, with bony destruction and thinning of cortical margins. MR findings are more rare: on coronal T1-weighted images the lesion appeared as a mass, isointense to gray matter, centered in the right petrous bone; on axial T2-weighted images, as a mixed-intensity signal mass. They conclude that MR is an accurate indicator of the location and extension of the tumor, but that CT gives more specific information regarding bone involvement.
