Clinical Experience on Dural Sinus Thrombosis

Cerebral dural sinus thro-bosis(DST) has been described as a rare and severe disease, clinically characterized by headache, papiliedema, seizures, focal deficits,progressive coma and even to death With the, advances ih diagnostic tools particularly MRI, DST is more commonly detected and index of suspicion is being increased. In order to characterize clinical features of DST that has been rarely reported in this country, we investigate a series of 14 patients with radiologically cerebral dural sinus thrombosis. It showed a highly variable mode of onset, diverse causes and unpredictable clinical courses. DST consists of heterogenous disease entities, with more broad spectrum of clinical presentation. Outcome was felt to be rather favorable than previously thought. Therefore, early consideration of the possibility, proper neuroimaging diagnosis and appropriate therapeutic trial on individual basis is recommended in the management of DST.

Spontaneous Intracranial Hypotension: MRI findings

Spontaneous Intracranial Hypotension(SIH) is a rare syndrome of spontaneous postural cephalalgia associated with low CSF pressure and usually without evidence of CSF leakage from meningeal defect due to dural puncture. The postural headache may appear suddenly or gradually and disappear within several weeks spontaneously. MRI findings maybe include diffuse symmetric pachymeningeal gadolinium-enhancement, also subdural effusion and downward brain displacement. We report two cases of SIH in which MRI of the brain reveals diffuse symmetric pachyme-ningeal enhancement.
