A strategy for taking a medical history focused on CSF leak symptoms to help improve diagnostic accuracy and initiate appropriate testing is provided.
Abstract
Spinal cerebrospinal fluid (CSF) leaks, including spontaneous intracranial hypotension, can be difficult to diagnose, requiring a high level of suspicion. Although the diagnosis is obvious in patients presenting with a new onset of coat hanger, orthostatic headaches that improve quickly in recumbence, the symptoms can be much more nuanced. Patients often experience misdiagnosis and delayed diagnosis, particularly if their brain imaging is negative, resulting in a severely impacted quality of life. Thus, it is incumbent for clinicians to be aware of both common and uncommon manifestations of spinal CSF leaks and to consider the possibility of a spinal CSF leak in patients with atypical symptoms, chronic migraine unresponsive to multiple treatments, or new daily persistent headache. This article provides a strategy for taking a medical history focused on CSF leak symptoms to help improve diagnostic accuracy and initiate appropriate testing. Examples and a list of topics to discuss are included.
Introduction Spinal cerebrospinal fluid (CSF) leaks cause spontaneous intracranial hypotension (SIH) and are a recognized cause of chronic subdural hematoma (cSDH). In contrast, acute subdural hematoma (aSDH) without trauma as the initial manifestation of a spinal CSF leak appears to be exceedingly rare. Research quest...

Obstructive hydrocephalus is a serious and potentially life-threatening condition caused by the temporary blockage of cerebrospinal fluid (CSF) flow. Most cases require urgent intervention as spontaneous resolution is very uncommon. We present the case and brain imaging of a 63-year-old man who presented to the emergen...

Abstract Background During an evaluation for encephalitis, lumbar puncture (LP) plays a critical role in establishing a diagnosis. Repeat LP may be needed when the diagnosis remains in doubt, the specific etiology of encephalitis has not yet been identified, or to aid management decisions. However, findings on repeat L...

In patients with high clinical suspicion for IIH, as described in this manuscript, with supportive neuroimaging, LP may be safely deferred without compromising diagnostic accuracy or patient care.

Background and Objectives: Spinal cord stroke (SCS) is an underrecognized cause of severe acute myelopathy in children that can be misdiagnosed as an infectious or inflammatory process. Limited characterization of clinical and neuroimaging features of pediatric SCS impede timely and accurate diagnoses. Our objectives w...

Functional neurological disorder (FND) is a diagnosis grounded in positive clinical signs, yet it remains vulnerable to underdocumentation and incomplete communication across care transitions, particularly when it is suspected but not formally recorded. In this case, a 24-year-old woman with a history of major trauma (...
