A total of 110 computed tomographic scans of the brain in pediatric population were reviewed. They wereretrospectively analyzed focusing on the ventricular dilatation, widening of subdural space in frontal region andprominence of cerebral sulci in hemisphere. The results were compared with clinical recored. In the measurementbicaudate ventricular index waas above 0.18, which ws considered ventricular dilatation. The subdural space in thefrontal region and teh prominent cerbral sulci in the hemisphere were visualized among the cases aged over twoyears with clinical evidence of cerbral problem is pediatric population. The diagnostic application of CT to thecases of cerebral disorder in pediatric population is highly recommended.

Coexistence of cranial and spinal subdural hematomas is rare and only a few cases have been reported in the literature. Herein, we report a case of cranial and spinal subdural hematomas after previous head trauma. As the pathogenesis of simultaneous intracranial and spinal subdural hematoma yet remains unclear, we developed an alternative theory to those proposed in the literature for their coexistence, the migration of blood through the subdural space.

An intracerebral aneurysm usually bleeds into the subarachnoid space in addition it may also rupture into the subdural space or into the brain, and it is reported that approximately 2-8 percent of all ruptured aneurysm have an associated subdural hematoma. We had experienced 4 cases of subdural hematoma following ruptured intracerebral saccular aneurysm from 1983 to 1985. They were distal anterior cerebral artery aneurysm and middle cerebral artery aneurysm, and 2 cases of anterior communicating artery aneurysm. There were no relationship between the amount of subdural hematoma and clinical course. With a view to the clinical course, 3 cases were acute, and one was chronic.

OBJECTIVE: The reaccumulation of hematoma is one of the most frequent problems on the chronic subdural hematoma. The aim of this study is to determine the factors affecting the reaccumulation of hematoma and the reasonable site for the burr-hole trephination to achieve a low reaccumulation rate after burr-hole trephination and closed-system drainage METHODS: The authors studied 93 patients with chronic subdural hematoma in whom the location of burr-hole trephination was randomly placed and precisely determined on postoperative brain computerized tomographic scans or skull roentgenogram. Eighty five patients with chronic subdural hematoma were obtained with brain computerized tomographic scans the postoperative 3 day. The location of the burr-hole trephination, the location of subdural catheter tip, the maximum postoperative width of the subdural space, and the percentage of the ipsilateral subdural space occupied by air postoperatively were measured and analyzed the correlation with the postoperative reaccumulation rates. RESULTS: Patients with the parietal trephination had much more subdural air and a higher of chronic subdural hematoma reaccumulation than those with the frontal one. In addition, patients with residual subdural air on brain computerized tomographic scans obtained the postoperative 3 day also had a higher reaccumulation rate than those without subdural air collections. CONCLUSION: The incidence of postoperative subdural fluid reaccumulation can be reduced by the burr-hole trephination on the frontal convexity and by preventing subdural air accumulation during operation.

Although magnetic resonance imaging (MRI) is frequently used to assess the lumbar spine, there are few reports in the medical literature that have evaluated using MRI immediately following spinal surgery. Furthermore, descriptions of the subdural changes after lumbar spine surgery are also infrequent. In this paper, we present two cases with subdural change seen on MRI immediately after lumbar surgery. Both the patients had mild symptoms that resolved spontaneously, and the follow-up MRI scans showed resolution of the subdural changes. Subdural changes should be considered as one of the possible causes of unexpected symptoms in patients following lumbar spinal surgery.

Meningioma arises from the arachnoid cap cell found in the arachnoid layer of the meninges. Most meningiomas are located in the subdural space. Meningiomas are mostly found in adulthood between 20 and 60 years of age. A case of intracranial epidural meningioma without involvement of the subdural space is reported.

Two cases of subdural tension pneumocephalus were introduced after posterior fossa surgery in the sitting position. The possible mechanism for entry of air into the subdural space is explained as the fluid pours out air bubbles to the top of the container. All of two cases manifested generalized seizure at recovery room and were diagnosed with plain skull series and computed tomogram. Subdural air evacuated patient fail to recover as expected, following posterior fossa surgery in sitting position.

OBJECTIVE: Chronic subdural hematoma (cSDH) is a common disorder that is readily surgically treated but has high recurrence rate. This is a preliminary report to evaluate the effectiveness of a newly designed catheter compared with the conventional one in treating cSDH. METHODS: We conducted a retrospective study of 111 patients with unilateral chronic subdural hematoma treated by burr hole craniostomy with closed-system drainage from November 2009 to September 2012. Group A was defined as patients treated with an external ventricular drainage (EVD) catheter and B as patients treated with the new catheter. We measured changes of thickness of hematoma and midline shifting in brain computed tomography (CT), amount of drainage and recurrence rate in both groups. RESULTS: Group A consisted of 54 and B of 57 cases. The mean duration for total removal of hematoma was 42.6+/-13.9 hours in group A and 30.3+/-11.9 hours in group B (p<0.05). The mean amount of drainage counted per six hours cumulatively differed significantly between groups. The result (p<0.05) showed that the newly designed catheter effectively removed the hematoma. The total recurrence rate in group A was 11% and 3.5% in group B. CONCLUSION: The study showed that the newly designed catheter effectively removed the hematoma in less time than the conventional one. This helps re-expand the brain block CSF from flowing into the subdural space and decrease the recurrence rate.

PURPOSE: To describe the MR imaging findings of traumatic spinal subdural hematoma. MATERIALS AND METHODS: We retrospectively reviewed the MR images of six patients, with symptoms of acute spinal cord or cauda equena compression after trauma, together with spinal subdural hematoma. We analysed the extent, location, configuration and signal intensity of the lesions. RESULTS: In five of six cases, hematomas were distributed extensively throughout the thoracolumbosacral or lumbosacral spinal levels. In five cases they were located in the dorsal portion of the thecal sac, and in one case, in the ventral portion. On axial images, hematomas showed a concave or convex contour, depending on the amount of loculated hematoma. A lobulated appearance was due to limitation of free extension of the hematoma within the subdural space at the lateral sites (nerve root exist zone) at whole spine levels, and at the posteromedian site under lumbar 4-5 levels. CONCLUSION: In cases of spinal subdural hematoma, the lobulated appearance of hematoma loculation in the subdural space that bounds the lateral sites at all spinal levels and at the posteromedian site under L4-5 levels is a characteristic finding.

Ninety-seven patients with chronic subdural hematoma were treated surgically between 1983 and 1992. The case records and radiological findings on computerized tomography(CT) scan were studied with regard to surgical outcome and postoperative brain expansion after burr hole craniostomy and closed system drainage. Male:Female ratio was 3.6:1 and the peak incidence was in the sixth decade of life. The patients were graded according to the scale used by Markwalder et al. and 56% were in Grade 0 and 1. The CT scan demonstrated the brain expansion and resolution of subdural space within 2 weeks in 53% of patients. Risk factors causing poor postoperative brain expansion were poor intraoperative brain expansion, too young(below 20 years) or too old(more than 71 years) age, and underlying disease. Following surgery, most of the patients improved. Whereas at the time of admission only 7% were neurologically normal(Grade 0), 67% of the patients fell into this category during the postoperative phase and 90% of the patients were postoperatively in Grade 0 and 1. Four patients died in the hospital, for a mortality rate of 4.1%. The most important factor influencing outcome was preoperative neurologic state.
