BACKGROUND We describe the case of a 38 year old male with Marfan syndrome who presented with orthostatic headaches and seizures. CASE PRESENTATION The patient was diagnosed with Spontaneous Intracranial Hypotension secondary to CSF leaks, objectively demonstrated by MR myelogram with intrathecal contrast. Epidural autologous blood patch was administered at the leakage site leading to signifi...

OBJECTIVE Chiari malformations are regarded as a pathological continuum of hindbrain maldevelopments characterized by downward herniation of the cerebellar tonsils. The Chiari I malformation (CMI) is defined as tonsillar herniation of at least 3 to 5 mm below the foramen magnum. Increased detection of CMI has emphasized the need for more information regarding the clinical features of the disord...

The hindbrain herniation syndrome (51), often referred to as the Chiari I malformation, is a disorder that has traditionally been defined as a downward herniation of the cerebellar tonsils through the foramen magnum (8, 9, 36). The extent of tonsillar herniation is recognized as being more than 4 to 5 mm below the plane of foramen magnum on sagittal magnetic resonance images (11, 13, 28, 30, 33...

The cough/laugh syndrome is characterized by the onset of severe headache immediately after an episode of coughing, laughing, or straining. It has been associated with pathologic changes in the posterior fossa, in particular, cerebellar tonsillar herniation or ectopia [1-3]. MR imaging is important in the evaluation of craniocervical anomalies, particularly Chiari malformations [4, 5]. We prese...

A 60-year-old man presented with headache, dizziness, and disorientation one day after consumption of isopropanol along with ethanol. Computed tomography (CT) of the brain performed immediately was unremarkable. The patient collapsed within the hospital 30 minutes after the CT scan was done, and remained comatose until death, showing no improvement with symptomatic treatment. Magnetic resonance...
