SUMMARY: Rebound intracranial hypertension is a complication of epidural blood patching for treatment of intracranial hypotension characterized by increased intracranial pressure, resulting in potentially severe headache, nausea, and vomiting. Because the symptoms of rebound intracranial hypertension may bear some similarity to those of intracranial hypotension and literature reports of rebound...

Introduction Spontaneous intracranial hypotension (SIH) is a secondary cause of headache often misdiagnosed and underdiagnosed disorder. The main presentation orthostatic headache. An uncommon symptom cranial nerve palsy. We described case SIH that presented to our service with sixth Case Report Female, 39 years old, no relevant medical past or history trauma, awoke due intense holocranial head...

A 37-year-old woman presented with acute orthostatic hypotension and diffuse headache. Brain magnetic resonance imaging (MRI) revealed T2 hyperintense bilateral subdural effusions, diffuse pachymeningeal enhancement, slit ventricles and venous engorgement compatible with spontaneous intracranial hypotension. Single photon emission computed tomography with computed tomography (CT) and CT-cistern...

Camptocormia is defined as an abnormal flexion of the thoracolumbar spine that appears while standing or walking. It is associated with several clinical situations such as parkinsonism, dystonia, and neuromuscular disorders. We present the case of a 33-year-old man who had marked camptocormia with acute onset (video on the Neurology® Web site at Neurology.org). The patient also had a 2-day hist...

Intracranial hypotension is characterized by a postural headache which is relieved in a supine position and worsened in a sitting or standing position. Although less commonly reported than postural headache, sixth nerve palsy has also been observed in intracranial hypotension. The epidural blood patch (EBP) has been performed for postdural puncture headache, but little is known about the proper...

AIM Intracranial hypotension may have variable clinical presentation. The imaging characteristics of intracranial hypotension are especially well depicted on magnetic resonance imaging studies. Although the clinical and radiological manifestations of spontaneous intracranial hypotension are increasingly recognized in many reports, many other abnormalities in this disorder and complicating cases...

OBJECTIVE AND IMPORTANCE Spontaneous intracranial hypotension is an increasingly recognized cause of postural headache. However, appropriate management of obtundation caused by intracranial hypotension is not well defined. CLINICAL PRESENTATION A 43-year-old man presented with postural headache followed by rapid decline in mental status. Imaging findings were consistent with the diagnosis of ...

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...
