Two cases of spinal arachnoid cysts are reported. One is extradurally located, the other intradurally. The first is only documented with myelography, the second also by subsequent CT scanning. Some clinical and diagnostic aspects of the lesion are discussed. The aim of this report is to add two new cases to the literature and to emphasize the role of high-resolution CT scanning in the diagnosis of these lesions.
The case of a 1-year-old boy with an acute infratentorial subdural hematoma is presented. Surgical intervention revealed a bleeding vein at the edge of a right-sided tentorial tear. Traumatic tentorial tearing has been demonstrated previously only in neonates. Although computed tomography is the most effective method for recognition of this lesion, vertebral angiography may be mandatory for more accurate localization.

A case of a malignant neurofibroma of the cauda equina is described. Its location seems to be rare. An extensive surgical resection including the adjacent neural tissue and the enveloping dural sac was carried out, followed by radiotherapy.
The modern technique of operative repair of traumatic nerve interruption is discussed. The results of microsurgical repair have proved to be superior to those of conventional methods. Besides the anatomy and the operative technique, the indications and timing for surgical intervention are discussed. Reference to the literature and the authors' own experience show that delayed primary repair is the method of choice.
