ABSTRACT
The authors report two cases of intradural spinal cord. The first is located in the thoracic segment, the second has a cervico-thoracic seat. In the two cases these spinal cords lipoma are responsible for a progressive medullary compression. In this article the authors make a succinct review of the literature. They underline also the fundamental part of the MRI for the diagnosis and the injured balance sheet of the intradural spinal cord lipoma.

The authors report a case of subdural spinal hydatid cyst. A diagnostic error was responsible for a communication between the cavity and the arachnoid space during resection of the cyst. Despite of this incident no other site was detected in this patient.

Recurrent meningiomas are due usually to incomplete removal as in the case of basal meningiomas where the tumour surrounding vessels and nervous structures cannot be completely excised. Recurrent meningiomas of the convexity are rare after resection. In most recurrent cases histological changes are noted which may explain the rapid growth, the aggressive nature and also the malignancy of the tumour. These changes include increased mitotic activity, necrosis and invasion of the adjacent brain parenchyma. CT findings in malignant meningiomas are related to the microscopic appearance of these tumours: tumoral necrosis determines heterogeneous enhancement; brain invasion explains the irregular outline of the tumour and sometimes the absence of surrounding low attenuation area. The authors report 5 malignant meningiomas in which the CT findings are correlated with the microscopic findings.

A case of metastasis to the thoracic spinal subdural space is reported. Metrizamide myelography showed narrowing of the upper thoracic subarachnoid space. A tumor in the spinal subdural space is unusual; only a few cases have been reported. The myelographic appearance is not specific; an epidural metastasis can produce the same myelographic picture.
