1/9. Epidural blood patch in a patient with an arachnoid cyst.

    arachnoid cysts are relatively common occurrences, with the majority being asymptomatic. The safety of an epidural blood patch in a patient with an arachnoid cyst has not been reported. Our patient had a known thoracic arachnoid cyst and required epidural blood patch for a postdural puncture headache. magnetic resonance imaging obtained following the epidural blood patch demonstrated no alterations of the cyst or spinal cord compression.

2/9. Helmetlike skull deformity with a large arachnoid cyst.

    BACKGROUND: It is not difficult to find localized skull ballooning or macrocrania in patients with intracranial arachnoid cysts. However, there have been no previous reports regarding large localized skull protuberant deformities resembling a war helmet. The authors report with a review of literature a case of an adult with helmetlike skull deformity resulting from a large supratentorial arachnoid cyst. CASE DESCRIPTION: A 35-year-old man presented with a large head deformity since his early childhood that had been the result of gradual progression from infantile macrocrania. He also had mental retardation, sixth cranial nerve palsy with recent aggravation of headache, reduced activity, poor voiding control, and walking disturbance. magnetic resonance imaging of the head showed hydrocephalus with a large supratentorial arachnoid cyst located in the bilateral parietooccipital area compressing the hemisphere anteriorly, and the tentorium and cerebellum inferiorly. Magnetic resonance venogram demonstrated low-lying short transverse and lateral sinuses, and the superior sagittal sinus and falx were displaced to the right side. Radioisotopic cisternogram showed nonfilling of the isotope in the bilateral parietooccipital area. cerebrospinal fluid pressure measured by lumbar puncture was 17 cm H(2)O. We tentatively diagnosed the condition as normopressure hydrocephalus with a large supratentorial arachnoid cyst. His headache, reduced activity, poor voiding control, and walking disturbance improved after a cystoperitoneal shunt. CONCLUSIONS: This might suggest that large arachnoid cysts found in childhood should be treated for prevention of skull deformity and late aggravation of increased intracranial pressure.

3/9. Post-dural headache associated with thoracic paravertebral blocks.

    The thoracic paravertebral block is effective in providing anesthesia and postoperative analgesia for thoracic and abdominal surgeries. This case report describes a suspected post-dural puncture headache following bilateral thoracic paravertebral blocks for postoperative analgesia after an umbilical hernia repair.

4/9. Intraventricular choroid plexus "arachnoid" cyst. MRI findings.

    A young women presented with chronic headaches associated with a cyst of the right lateral ventricle. The diagnosis of intraventricular so-called "arachnoid" cyst was supported by CT scan, MRI and stereotactic puncture. MRI was of great value for demonstrating that the cyst was located within the lateral ventricule, that it was delineated by a thin wall adherent to the choroid plexus and that the cyst content was CSF-like.

5/9. Stereotactic cysto-ventricular shunting in diencephalic (arachnoid) cysts and failure in cystic craniopharyngeoma.

    Stereotactic cysto-ventricular shunting in three patients with congenital (subependymal cyst of the 3rd ventricle, subependymal cyst of the foramen of Monro, cyst of cavum septi pellucidi) and in a female patient with a large cystic suprasellar craniopharyngeoma is dealt with in this paper. The first operation was performed in May 1992 and the latest, being considered in this paper, in October 1993. All patients were admitted to our hospital suffering from signs of increased intracranial pressure. CT-scans revealed on the one hand an obstructive hydrocephalus subjected to the cystic arachnoid lesions, on the other hand a large hypodense suprasellar cystic tumor. After stereotactic puncture of the arachnoid cysts, aspiration of their contents as well as biopsy of the wall, a silicone catheter was implanted, thus constructing a permanent communication between the cyst and the lateral or third ventricle. The internal catheter was connected to a subcutaneous burr-hole reservoir. All these patients recovered uneventfully without neurological deficits. There were no operative complications. Follow-up CT-scans showed no recurrences of the cysts and obstructive hydrocephalus. In the patient with the suprasellar craniopharyngeoma at first a stereotactic puncture of the cyst was performed. After recurrence the tumor was directly approached by an frontotemporal craniotomy. The histological examination revealed now a craniopharyngeoma. After renewed recurrence a stereotactic cysto-ventriculostomy with internal shunt implantation was performed. However, in this case this method was unsuccessful, documented by follow-up CT-scans. Resulting from our experiences, it is quite obvious that the stereotactic internal shunt implantation seems to be a safe, proper and reliable method in the treatment of arachnoid cystic lesions.(ABSTRACT TRUNCATED AT 250 WORDS)

6/9. Stereotactic cysto-ventricular shunting in diencephalic (arachnoid) cysts.

    Stereotactic cysto-ventricular shunting in three patients with congenital (subependymal cyst of the 3rd ventricle, subependymal cyst of foramen of Monroi, cyst of cavum septi pellucidi) is dealt with in this paper. The first operation was performed in May 1992 and the latest, being considered in this paper, in January 1993. All patients were admitted to our hospital suffering from increased intracranial pressure. CT-scans revealed an obstructive hydrocephalus subjected to the cystic lesions. After stereotactic puncture of these cysts, aspiration of their contents as well as biopsy of the wall a silicone catheter was implanted, thus constructing a permanent communication between the cyst and the lateral or 3rd ventricle. The internal catheter was connected to a subcutaneous burr-hole reservoir. All patients recovered uneventfully without neurological deficits. There were no operative complications. Follow-up CT-scans showed no recurrences of the cysts and obstructive hydrocephalus. Resulting from our experiences, it is quite obvious that the stereotactic internal shunt implantation seems to be a safe, proper and reliable method in the treatment of such cystic lesions. Open craniotomy or intracorporal shunting procedures and their immanent complications can be avoided for most cases of congenital intracranial cysts. It should, therefore, be the aim of further clinical investigations to prove the value of this method in additional cases.

7/9. Symptomatic spinal intradural arachnoid cyst development after lumbar myelography. Case report and review of the literature.

    STUDY DESIGN: This case report describes the unique occurrence of acquired intradural spinal arachnoid cyst after lumbar puncture, which was proven radiographically and surgically. OBJECTIVES: To review and explore complications of lumbar puncture in the context of subsequent cyst development and to review the incidence, presentation, pathogenesis, and management of spinal intradural arachnoid cysts. SUMMARY OF BACKGROUND DATA: The etiology of the spinal intradural arachnoid cyst remains obscure; some such cysts are ascribed anecdotally to previous trauma or arachnoiditis, whereas the majority are idiopathic and assumed by many authors to be congenital. methods: A 20-Year-old woman with back and leg pain underwent lumbar myelography that yielded normal results with no evidence of arachnoid cyst at that time. Within 5 months, clinical symptoms of cauda equina compression and an S1 radiculopathy developed. Subsequent myelography and magnetic resonance imaging revealed a lumbar spinal arachnoid cyst. There was no history of intervening trauma or arachnoiditis. The lumbar puncture was thought to be the cause of the arachnoid cyst. RESULTS: A laminectomy was performed with complete excision of the arachnoid cyst. The patient had an unremarkable postoperative course with excellent relief of her symptoms. CONCLUSIONS: This case provides supporting evidence for the traumatic etiology of spinal intradural arachnoid cyst. The development of an intradural spinal arachnoid cyst should be included as a possible complication of lumbar puncture.

8/9. Multiple communicating intradural arachnoid cysts: usefulness of myelography and myelo-computed tomography using both lumbar and cervical punctures. Case report.

    We report a case of multiple communicating intradural cystic lesions. magnetic resonance imaging did not demonstrate the lesions. Neuroradiological diagnosis of the intradural arachnoid cysts was made from myelography and myelo-computed tomography using both lumbar and cervical punctures. These procedures give us useful information about flow dynamics in the spinal subarachnoid space.

9/9. Usefulness of neuroendoscopy in treating supracollicular arachnoid cysts--case report.

    A 12-year-old girl presented with a supracollicular arachnoid cyst manifesting as a compressive headache. Neurological examination on admission revealed no deficit except bilateral papilledema. Stereotactic cyst puncture failed to perforate the cyst wall. The wall was then punctured using microforceps under neuroendoscopic guidance, followed by cystoperitoneal shunting. Her headache disappeared immediately after surgery. neuroendoscopy is useful in treating a deep-seated arachnoid cyst.
