1327 December 2014 B ecause of cerebrospinal fluid (csF) leak, orthostatic headaches sometimes follow neuraxial blockade or diagnostic lumbar puncture. etiology and treatment are straightforward in those settings, since a site of dural disruption is known.1,2 With patient consent, we present a case in which intracranial hypotension resulted from dural puncture by a vertebral osteophytic spur. T...

Spontaneous intracranial hypotension (SIH) is caused by leakage of CSF, and characterized on MRI by brain sagging, dilatation of veins and dural sinuses, subdural fluid collections and post-contrast enhancement of the thickened dura. A few cases may present a very severe brain sagging through the tentorial notch and swelling of the diencephalic-mesencephalic structures, with absent or scarce su...

INTRODUCTION Headache is a common presenting complaint and has a wide differential diagnosis. Clinicians need to be alert to clues that may suggest an underlying secondary aetiology. We describe a novel case of headache secondary to intracranial hypotension which was precipitated by the rupture of a spinal arachnoid cyst. CASE REPORT A 51-year-old Indian female presented with sudden onset sev...

BACKGROUND AND PURPOSE CT myelography has historically been the test of choice for localization of CSF fistula in patients with spontaneous intracranial hypotension. This study evaluates the additional benefits of intrathecal gadolinium MR myelography in the detection of CSF leak. MATERIALS AND METHODS We performed a retrospective review of patients with spontaneous intracranial hypotension w...

BACKGROUND AND PURPOSE Spontaneous intracranial hypotension can be a therapeutic challenge to the treating physician. In this study, we present our experience with the administration of a large-volume blood patch to multiple sites in the epidural space through a single-catheter access site. MATERIALS AND METHODS A retrospective review was conducted of patients with spontaneous intracranial hy...

We report a case of spontaneous intracranial hypotension with classic symptoms of orthostatic headache and acute presentation of subdural haematoma on computed tomographic scan. Conventional approach with conservative treatment was initially adopted. The patient's condition, however, deteriorated after 2 weeks, requiring surgical evacuation of the intracranial haemorrhage. We reviewed the clini...

Spontaneous intracranial hypotension (SIH) is a rare cause of persistent headache, particularly among young and middle-aged people. A potentially life-threatening complication SIH cerebral venous thrombosis (CVT). The authors present case in which patient presented with complicated by CVT one week after receiving booster dose mRNA COVID-19 vaccine. According to our literature review, this the f...
