The authors present the case of a 55-year-old man suffering from intractable spontaneous intracranial hypotension, in whom conservative treatment with 19 weeks of bed rest was not effective. In this period the patient twice underwent surgery for bilateral chronic subdural hematoma, a complication of spontaneous intracranial hypotension. Conventional radionuclide cisternography, magnetic resonan...

A 34-year-old woman came to the emergency room complaining of a severe orthostatic headache. Results of a cerebrospinal fluid tap and brain computed tomography were normal. Based on her history and symptoms, she was found to have spontaneous intracranial hypotension. She was hospitalized and her symptoms improved with conservative treatment. On the next day, her headache suddenly worsened. Cist...

The syndrome of spontaneous intracranial hypotension is characterised by postural headache, low CSF pressure, and MRI findings of diVuse pachymeningeal gadolinium enhancement without a history of head or back trauma or lumbar puncture. We report on the MRI findings of a patient with spontaneous intracranial hypotension, before and after treatment. A 44 year old woman presented with severe subac...

The following interesting and uncommon headache disorders are presented through case studies: exploding head syndrome, hypnic headache, neck-tongue syndrome, "Alice in Wonderland" syndrome, nummular headache, red ear syndrome, burning mouth syndrome, spontaneous intracranial hypotension syndrome, and cardiac cephalalgia.

Recovery in Spontaneous Intracranial Hypotension I have read with interest the article by Tosaka et al in the June-July 2008 issue of the American Journal of Neuroradiology. The authors describe with exquisite detail the characteristics of dural and subdural fluid in spontaneous intracranial hypotension. They have recognized and collected cases describing a new sign of lineal dural hyperintensi...

BACKGROUND There is a paucity of quality data on the incidence of adverse outcomes of chiropractic manipulation. Spontaneous intracranial hypotension (SIH) subsequent to cervical spinal manipulation has been documented. However, no imaging correlates have previously been presented demonstrating a clear causal relationship to manipulation with follow-up and correlating with clinical symptomatolo...
