Meningiomas are amongst the most common primary brain tumors, accounting for around one third of cases. They usually present with focal neurological deficits, signs of raised intracranial pressure or seizures. Transient global amnesia (TGA) is an uncommon disorder, usually linked with severe emotional or physical stress, migraine variant or vascular risk factors. It is believed to originate from hippocampal dysfunction. We present the case of a 65 year female, who visited our hospital with two episodes of transient amnesia. Both episodes lasted for 4-5 hours with no other focal neurological dysfunction noted. She fit the diagnostic criteria for TGA and seizures were ruled out by a normal sleep-deprived electroencephalogram (EEG). Magnetic Resonance Imaging (MRI) of Brain showed the presence of a right frontal meningioma. We conclude that she suffered from TGA secondary to right frontal meningioma, a rare association of which only a handful of cases have been reported worldwide

AbstractThe presence of magnetic resonance imaging (MRI) abnormalities in patients with transient global amnesia has been an interesting phenomenologic finding. Several theories surround the occurrence of this syndrome, but little is known about its true physiopathology. We present a case of transient global amnesia after cardiac catheterization associated with migraine headache and MRI changes compatible with an ischemic insult. A discussion on potential explanations for this finding is made, as well as a review of the pertinent literature.

Age Range

Valsalva maneuver (VM) precedes frequently transient global amnesia (TGA) and up to 84% of the patients with TGA present hippocampal diffusion-weighted imaging-positive (DWI+) lesions on brain magnetic resonance imaging (MRI). We studied 20 patients with TGA and hippocampal DWI+ lesions. Median age (range) of the patients was 67 (57–80) years and 55% were women. TGA had been preceded by a VM-associated activity in 14 patients (70%), and brain MRI had been performed at a median (range) of 47.5 (42–79) h after TGA. These patients underwent a second MRI after a controlled-induced VM at least 3 months after TGA. This MRI was performed at a median (range) of 46.8 (41–138) h after the controlled-induced VM. None of the patients who reproduced TGA symptoms presented new DWI+ lesions on the second MRI. In patients with a previous episode of TGA, VM cannot elicit TGA in isolation and the interplay of other simultaneous factors is needed.

Spinal Epidural

Spinal epidural abscess (SEA) is a rare disease which is often rapidly progressive. Delayed diagnosis of SEA may lead to serious complications and the clinical findings of SEA are generally nonspecific. Paraspinal abscess should be considered in the presence of local low back tenderness, redness, and pain with fever, particularly in children. In case of delayed diagnosis and treatment, SEA may spread to the epidural space and may cause neurological deficits. Magnetic resonance imaging (MRI) remains the method of choice in the diagnosis of SEA. Treatment of SEA often consists of both medical and surgical therapy including drainage with percutaneous entry, corpectomy, and instrumentation.

Progressive Weakness

A young adult female with restricted water intake during the postpartum period presented with history of progressive weakness, dizziness and tendency to fall with generalized slowing of movement. On examination, patient was anaemic, febrile and stuporous. Investigations revealed hypernatremia, delta waves in electroencephalogram (EEG) and features suggestive of extra-pontine myelinolysis on magnetic resonance imaging (MRI) of brain. After correcting hypernatremia and instituting anti-cholinergic therapy, there was a gradual but steady improvement in neurological symptoms of the patient over a period of one week and the patient was discharged in a conscious, oriented and ambulant state. As such, neuroimaging findings can be crucial in diagnosing hypernatremic encephalopathy in the postpartum period.

Background Isolated body lateropulsion is a possible predominant manifestation of medulla oblongata infarction, and can occur without vestibular and cerebellar symptoms. However, it is relatively rare and challenging to diagnose. Case presentation A 67-year-old woman was admitted to the Harris International Peace Hospital complaining mainly of instability when standing and walking for the previous 8 hours. Based on the neural localization and multiple head magnetic resonance imaging (MRI) examinations, a diagnosis of cerebral infarction (vertebrobasilar system) was made. Consequently, the patient was managed using therapy aimed at preventing platelet aggregation, lowering plasma lipids, stabilizing plaques, protecting mitochondria, and improving circulation and brain function. The patient’s gait improved and she was discharged after 14 days because she was able to walk unaided. The patient was followed up for 6 months and had no noticeable undesirable side effects or signs of neurological deficits. Conclusion The possibility of lateral medulla oblongata infarction should be considered when patients present with isolated body lateropulsion, without other signs or symptoms of brainstem damage.

Global Amnesia

Hippocampal infarction is relatively rare. Many different diseases can mimic hippocampal infarction including transient global amnesia, Alzheimer’s disease, epilepsy, encephalitis, and encephalopathies. An 89-year-old man was transported to our hospital for altered consciousness. Diffusion-weighted magnetic resonance imaging revealed slightly intense signals in the hippocampus with a mildly decreased apparent diffusion coefficient. Serial magnetic resonance imaging revealed features of hippocampal infarction. Symptoms and cognitive function gradually improved with rehabilitation, and he was transferred to a rehabilitation facility on Hospital Day 38. Hippocampal infarction is rare in patients with altered mental status, but should be considered when magnetic resonance imaging shows findings suggestive of this condition. Other differential diseases should be ruled out by serial magnetic resonance imaging and observation of the clinical course.
