RESUMEN
INTRODUCTION: A case of accumulation of CSF into the brain parenchyma simulating a brain tumor, secondary to an obstructed ventriculoperitoneal shunt, is presented. Until now, only seven cases of this rare complication have been described. CASE REPORT: Magnetic resonance showed an expansive, low-density intracranial lesion on the right frontal and parietal lobe. This mass was biopsied, but no tumor was found and the diagnosis was brain edema. CONCLUSION: The mistake in the diagnosis was due to the clinical symptoms and to the MR images.

STUDY DESIGN: Dorsal spinal cord compression caused by amyloid tissue deposits in the posterior vertebral arch and epidural space of the T6-T7 region in a 29-year-old woman is reported. RESULTS: Studies did not show any primary cause of amyloidosis. CONCLUSIONS: This case can be classified as primary localized tissue because other causes and amyloid deposits were not discovered. This patient was the youngest person reported to have dorsal spinal cord compression caused by amyloid tissue deposits, and the spinal cord compression was localized in the thoracic region, which occurred in six of the seven cases reported.

The authors review eight cases of thalamic tumors in children. Radical surgery was performed in seven cases. All cases were diagnosed by computed tomographic scanning, and histological diagnosis showed seven benign astrocytomas and one malignant astrocytoma. All patients are still alive. The treatment of these tumors is discussed.
