Spontaneous intracranial hypotension may share some characteristics with the more common causes of headaches such as migraines or tension headaches, but its diagnosis and treatment is much more laborious and invasive. Here, the case of a 31-year-old man with multiple weeks of positional headaches is described. This symptom persisted following multiple blood patches, and progressed to worsening mental status, encephalopathy, and eventually obtundation with Glascow Coma Score less than 8. Surgery was required; however, small improvement was seen on imaging or in the patient's status. When the patient's position was changed to 20 degrees of Trendelenberg, immediate improvement was seen, leading to a full recovery. Although epidural blood patch is considered the treatment mainstay for spontaneous intracranial hypotension, this case shows another factor to consider in the treatment of this difficult condition.

Background And Purpose: In patients diagnosed with spontaneous intracranial hypotension (SIH), microspurs are considered the culprit lesion in most ventral dural leaks (type I). The imaging characteristics of discogenic spurs, and their prevalence in the general population has not been reported in the literature.
Materials And Methods: This observational case-control study was conducted comparing the prevalence and characteristics of discogenic microspurs between SIH patients with a type I leak treated at a tertiary hospital between 2013 and 2023 and an age-and sex matched cohort of trauma patients.

Spontaneous intracranial hemorrhage (sICH) is a major complication associated with oral anticoagulation which results in a high mortality rate, and the incidence of anticoagulant-induced sICH has increased markedly, so it is necessary to investigate the risk of anticoagulation-related sICH in a real-world setting. We aimed to investigate the incidence and risk factors of oral anticoagulant-related sICH using a common data model (CDM), and to determine whether a clinical study using the CDM would be comparable to conventional studies. After converting the various clinical codes of 12,821 patients taking oral anticoagulants, such as warfarin and non-vitamin K antagonist oral anticoagulants (NOACs), into the Observational Medical Outcomes Partnership (OMOP) CDM format, we analyzed the incidence and risk factors of sICH.

Background: Orthostatic headache (OH) is a common feature of various conditions, including spontaneous intracranial hypotension (SIH), but no precise definition currently exists outlining the typical OH characteristics. This ambiguity risks misdiagnosis with unnecessary investigations and delay in institution of treatment. The present study aimed to carry out structured phenotyping of OH in patients with SIH with the aim of outlining its typical characteristics.

The purpose of this video is to introduce digital subtraction myelography for CSF-venous fistula (CVF) detectection. CVF is the most recently identified and likely the most prevalent type of spinal CSF leak that leads to spontaneous intracranial hypotension CVFs are occult on conventional MRI and CT, necessitating the use of myelography for the diagnosis. This video highlights one such technique, which is important because an increasing number of centers are starting to diagnose CVF.

We report a female patient in her 70s with mild cognitive impairment due to Alzheimer's disease (AD) who developed a left temporal lobar haemorrhage after the third dose of lecanemab, accompanied by non-traumatic haemorrhage in a pre-existing subdural hygroma, and was diagnosed with amyloid-related imaging abnormalities with haemorrhage. The patient exhibited mild verbal paraphasia and word recall difficulty but had no other major neurological deficits. There was no additional intracranial abnormality during the course of hospitalisation.
