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.

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

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.

Idiopathic hypertrophic pachymeningitis (IHP) is a rare disease, and it is characterized by chronic progressive inflammatory fibrosis and thickening of the dura mater with resultant compression of the spinal cord or neural structure without any identifiable cause. It can occur in the intracranial or spinal dura mater alone or as a craniospinal form. The spinal form is rarer than the cranial form and the craniospinal form is extremely rare. We report a rare case of IHP in the craniocervical junction involving both the cranial and spinal dura mater and discuss the diagnosis and management of the disease.

Meningiomas are thought to arise from the arachnoid cap or meningothelial cells. This frequent apposition to the dura mater probably accounts for the usual attachment of the neoplasm to this layer. We report a case of intraparenchymal meningioma without dural attachment in a 14-year-old girl. A survey of the literature reveals that the majority of cases of meningiomas without dural attachment occur either in children or below the tentorium, and most of them located in the ventricle, the cranial vault. Intraparenchymal meningioma without dural attachment, however, are extremely rare. The uncommon locations of meningiomas at sites distant from the duramater is believed to reflect the rare occurrence of arachnoid cap cells in the Virchow-Robin spaces along the cerebral vasculature or in the pial layers distant from the dura mater.

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

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.

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.

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.
