✓ Two cases are presented in which the patients developed an unusual complication following the use of an artificial dural substitute, silicone-coated Dacron (Dura Film). Both patients had undergone removal of a tumor and involved dura. The first patient developed a very thick connective-tissue capsule of the graft material which simulated a recurrent tumor. The second patient developed an acute hemorrhage initially thought to be an acute subdural hematoma beneath the artificial dura 9 weeks after tumor removal and implantation of the graft. A review of the literature and proposed mechanisms of these complications are presented.

Abstract A case is presented in which a patient developed an unusual complication after the use of Silastic dural substitute. In 1983. the patient underwent removal of a meningioma with the involved dura. Five years later, he developed around the graft material a very thick connective tissue capsule, which simulated a recurrent meningioma clinically and radiologically.

Complete Tumor

✓ Spinal ependymomas may rarely arise from heterotopic ependymal cell clusters and thus occur in an extraspinal location. Presentation of three cases and a review of the literature reveal that these tumors have characteristic radiographic and clinical features. They occur mainly in patients in the third decade of life, and present either in the soft tissue posterior to the sacrum or in the pelvis. In the case of posterior tumors, the patient exhibits a mass which is usually mistaken for a pilonidal cyst. Patients whose tumor is pelvic in location present with sphincter disturbances or dysfunction of the sacral nerve roots. Conventional and computerized tomographic studies will reveal erosion of the sacrum. Myelography will demonstrate an extradural mass indenting the thecal sac from below. The protein in the cerebrospinal fluid will be normal. A combined posterior and anterior approach with the goal of complete tumor removal is the procedure of choice. If this is not feasible, then radiation therapy should be employed. Because of the increased incidence of systemic metastases, the average postoperative survival is approximately 10 years.

✓ Many substances have been used as dural substitutes. Although the various materials are effective in a variety of settings, a material that is absorbed over time, elicits minimal inflammatory reaction, is relatively inexpensive, and is easily manipulated would be beneficial. An experimental project was conducted involving closure of dural defects in dogs with a Vicryl (polyglactin 910) mesh graft. Macroscopic and histological examination performed at various times after placement revealed resorption of the graft material, little cerebromembranous adhesion formation, and complete lack of injury to subjacent cortical zones. A substantial neomembrane forms over the zone of the mesh graft. The authors suggest that Vicryl mesh has significant potential as an absorbable, minimally reactive dural substitute.

✓ Intervertebral disc degeneration of any etiology may be associated with the formation of spaces or clefts within the disc. Gas collects within these spaces and can be seen roentgenographically. A case is presented in which intradiscal gas herniated into a connective tissue capsule, displacing the left S-1 nerve root and producing symptoms and signs identical to those of a herniated nucleus pulposus. The pathophysiology of gas within a disc space and the possibility that it may herniate much like the nucleus pulposus is discussed.

✓ Familial arteriovenous malformations (AVM's) are uncommon entities, with only seven reported cases in the English literature. Some have been associated with hereditary telangiectasia. A family in which AVM's were found in four male members of two generations is reported. In addition, one patient had a large cyst associated with his AVM without previous evidence of acute hemorrhage, which is an uncommon presentation. The family is discussed and a brief review of the literature is presented.

✓ The authors report a patient who became comatose from an unsuspected epidural hematoma over the occipital and suboccipital areas 3 hours after removal of a huge subfrontal meningioma. The correct diagnosis was eventually made by angiography 27 days postoperatively. This most unusual complication should be considered when unexplained deterioration occurs immediately after frontal tumor removal.

Object. The authors evaluated a new non—cross-linked, propylene oxide—treated, acellular collagen matrix for use as a dural substitute in rabbits. They then compared this material to a commonly used dural substitute as well as to native dura mater used during primary closure. Methods. Forty-six rabbits were randomly assigned to eight groups of five or six rabbits each. These groups differed according to the type of closure material that was used during surgery (native dura, control dural substitute, or experimental dural substitute) and the duration of convalescence. At the end of the experiment, the tightness of the duraplasty was assessed in each live rabbit by continuous infusion of fluid into the cisterna magna until leakage was detected. The animals were killed and each specimen was sectioned and studied histologically. The authors found that the experimental dural substitute was safe in animals for this application, that it held sutures well, and that a watertight closure was usually achieved. There were fewer adhesions between the experimental material and neural tissue was less likely to adhere to the cranium than the control graft. Histological examination showed that the experimental material had slightly more spindle cells and vascularity than the control graft. Conclusions. The experimental graft material has several features that make it an attractive candidate for use as a dural substitute.

✓ Two patients with benign intracerebral cysts are reported and a brief review of the literature is given. Although computerized tomography (CT) scanning is useful in detecting a variety of intracerebral cysts, the CT findings are not specific for any lesion. An exploratory operation with establishment of an adequate route of drainage and a histological examination of the cyst wall are mandatory in the management of patients with a progressive but benign lesion.
