Abstract:
In this report, we share the case of a 65-year-old male with a remote history of brain concussion who presented to the emergency department for evaluation of transient amnesia that lasted 30 minutes to one hour. He was found to have spontaneous intracerebral hemorrhage of the fornix as a cause of his amnesic episode. To date from the creation of this case report (January 2023), spontaneous hemorrhage of the fornix resulting in transient amnesia has not been previously described in the literature. The fornix is an unusual location for spontaneous hemorrhage to occur. The differential diagnosis of transient amnesia is broad and includes, but is not limited to, transient global amnesia, traumatic injury, hippocampal infraction, and various metabolic derangements. Determination of the etiology of transient amnesia can result in changes in treatment decisions. Because of this unique patient presentation, we propose that spontaneous hemorrhage of the fornix should be considered in patients who present with transient amnesia.
Insights
A rare case of spontaneous fornix hemorrhage caused transient amnesia in a 65-year-old male. This finding suggests fornix hemorrhage should be considered in amnesia evaluations.
Area of Science:
- Neurology
- Neuroscience
- Medical Case Reports
Background:
- Transient amnesia has a broad differential diagnosis, including transient global amnesia, traumatic brain injury, and metabolic derangements.
- Identifying the precise cause of amnesia is crucial for guiding appropriate treatment decisions.
Observation:
- A 65-year-old male with a remote history of concussion presented with transient amnesia lasting 30-60 minutes.
- Cerebral imaging revealed spontaneous intracerebral hemorrhage localized to the fornix.
Findings:
- This case represents the first reported instance of spontaneous fornix hemorrhage causing transient amnesia.
- The fornix is an uncommon site for spontaneous intracerebral bleeding.
Implications:
- Spontaneous fornix hemorrhage should be included in the differential diagnosis for patients presenting with transient amnesia.
- This unique case expands the understanding of potential etiologies for amnesic episodes.

01:13Amnesia
The severity and duration of memory loss vary depending on the type and underlying cause. Amnesia is classified into two main types: retrograde and anterograde.
Retrograde amnesia is marked by the loss of memories formed before the onset of the condition. Patients may recall distant past events but often forget those occurring shortly before the incident.
Anterograde...
