Subdural hematoma is a common disease of intracranial hemorrhage that accounts for 11-21% of all head trauma patients. It is defined as a hematoma that develops between dura mater and subarachnoid space. In elder patients, mild trauma may not always be accurately recognized and symptoms may not develop slowly due to the large area of subdural space. Headache is the most common symptom of subdural hematoma and may be associated with hemiplegia, dysarthria, sensation disorder, conscious disorder, and etc. We present, with a literature review, a case of a patient who developed subacute subdural hematoma after performing Brandt-Daroff habituation exercise to treat benign paroxysmal positional vertigo.

We report a case of deep sylvian meningioma without any dural attachment in a 36-year-old man. The patient presented with generalized tonic clonic seizure. Magnetic resonance images revealed a well enhancing round mass in the superior aspect of the left insular region. Surgical resection confirmed transitional type of meningioma. Gamma knife radiosurgery was undergone to control the tumor growth after partial resection. So far, supratentorial meningioma without any dural attachment has been rarely reported.

A case of metastatic renal cell carcinoma is reported. The tumor had imaging features of meningioma on brain computerized tomography and magnetic resonance.

Chondroblastoma is an uncommon benign chondroid neoplasm that occurs predominantly at the epiphysis of the long bones in the skeletally immature. Rarely chondroblastoma may occur in the skull. We report a case of a 36-year-old man with chondroblastoma arising from the right temporal bone. Radical excision of the tumor using the infratemporal fossa approach was performed and the involved dura was resected. There was no evidence of tumor recurrence 4 years after surgery. On the basis of this case and a review of the literatures, we recommend complete surgical excision including adjacent dura mater as the primary treatment for chondroblastoma of the temporal bone invading the dura mater.

We report a case of sellar tuberculoma without extracranial tuberculosis, mimicking pituitary adenoma. The clinical presentation and findings of magnetic resonance image were very similar to pituitary adenoma. Subtotal excision of the lesion was achieved via a transsphenoidal route. The dura mater was markedly thickened and the tumor was hard and avascular. A diagnosis of tuberculoma was made on the basis of histologic studies. However, there was no evidence of tuberculosis in smear for acid-fast bacilli and polymerase chain reaction. Nine months after the anti-tuberculous medication, computed tomography revealed no mass in the sellar region.

In a series of rabbits, two craniectomies were made in both side of the parietal hone. Each lesion was filled with gelfoam, lyocura, fat and dural film. Five rabbits were left empty as a control group. The animals were killed in one month after the operation. The degree of adhesion between the soft tissue of the scalp and various dural substitute was evaluated at the time of operative dissection and studied histopathologically. The results were as follows. 1) The insertion of dural substituted substances can prevent the adhesion between the scalp and dura mater. 2) The dural film was most effective in prevention of adhesion. 3) The dural film inserted group exhibited inflammatory reaction. 4) The gelfoam, lyodura and fat inserted groups were though to have had a moderate prevention effect of adhesion. With these results, we could conclude that the insertion of material between the dura and scalp can prevent adhesion. However the ideal inserted material which can pevent inflammatory reaction and adhesion has not been determined. At this point we have not found and ideal substitute. To get an ideal material for prevention of adhesion, further intensive study is required.

A case of malignant fibrous histiocytoma(MFH) arising from the pericranium which extend to the calvaria and the dura mater in a 32-year-old man is reported. This tumor presented as scalp induration and headache without any other neurologic abnormalities. Radical excision presented a surgical challenge because of the extensiveness of the lesion. In this case radical excision of pericranial and calvarial lesions were possible, however it is impossible to remove the lesion in the dura mater radically because of its extensiveness. Thus the radiation therapy was necessary after operation. Histologically, pericranial, calvarial and dura mater tumor tissues were same as that of the typical malignant fibrous histiocytoma of the soft tissue. The authors review the literatures of the MFH involving central nerve systems and discuss the management and the radiologic findings of this rare tumor.

Idiopathic hypertrophic pachymeningitis is a rare inflammatory disorder of the dura mater. Spinal involvement is extremely rare and there are few case reports. We present a 36 year-old female of idiopathic hypertrophic spinal pachymeningitis compressing thoracic spinal cord which showed rapid recurrence.

The authors present a case of solitary dural plasmacytoma. A 43-year-old woman was admitted our department due to headache. Brain magnetic resonance(MR) image showed homogeneous enhanced lesion at the left occipital area. We performed surgical excision and it was confirmed plasmacytoma, histologically. The solitary dural plasmacytomas are exceedingly rare. Before this case report, only 17 cases had been reported in the literature
