Intracranial hypotension: the nonspecific nature of MRI findings.

Headache

Headache and Pain Unit, Neurology Division, Hospital Churruca, Buenos Aires, Argentina.

Published: March 2001

We present three patients who complained of postural headache related to different types of intracranial hypotension: spontaneous or primary, and secondary, but presenting the same findings on brain magnetic resonance imaging. Diffuse pachymeningeal gadolinium enhancement supports the belief that the enhancement is a nonspecific meningeal reaction to low pressure.

Background: Cerebrospinal fluid (CSF) loss in spontaneous intracranial hypotension (SIH) is accompanied by volume shifts between the intracranial compartments. This study investigated tricompartimental and longitudinal volume shifts after closure of a CSF leak.

Methods: Patients with SIH and suitable pre-therapeutic and post-therapeutic imaging for volumetric analysis were identified from our tertiary care center between 2020 and 2023.

A potential two-way passage of cells and substances between the brain and skull bone marrow may open for new insights into neurological disease. The arachnoid membrane was traditionally considered to restrict cells and larger molecules in CSF from entering the dura and bone marrow directly. However, new data on exchange between brain and skull bone marrow have recently emerged.

Azygos Vein Stenosis in Frontotemporal Dementia Sagging Brain Syndrome.

Background And Purpose: Symptoms indistinguishable from behavioral-variant frontotemporal dementia (bvFTD) can develop in patients with spontaneous intracranial hypotension associated with severe brain sagging. An underlying spinal CSF leak can be identified in only a minority of these patients and the success rate of nondirected treatments, such as epidural blood patching and dural reduction surgery, is low. The disability associated with bvFTD sagging brain syndrome is high and, because of the importance of the venous system in the pathophysiology of CSF leaks in general, we have investigated the systemic venous circulation in those patients with recalcitrant symptoms.

Miyazaki syndrome.

BMJ Case Rep

January 2025

Neurosurgery, Unidade Local de Saúde de Lisboa Ocidental, Lisboa, Portugal.

Miyazaki syndrome is a rare complication in patients with ventricular shunts, characterised by cervical myelopathy from cerebrospinal fluid overdrainage. Here we report a case of a young woman with a history of hydrocephalus who had a ventricular shunt placed in infancy, presenting to our department with signs and symptoms of myelopathy due to overshunting. This diagnosis is challenging because of the frequent absence of typical signs of intracranial hypotension, leading to delays in treatment, which carries the risk of potentially devastating consequences.
