Transient global amnesia due to a dominant hemisphere tumor

|May 1, 1977
Summary
Transient global amnesia (TGA) is usually benign. However, this case highlights the importance of investigating TGA for underlying mass lesions, as a brain tumor can mimic TGA symptoms.
Area of Science:
- Neurology
- Neuroscience
- Pathology
Background:
- Transient global amnesia (TGA) is typically considered a benign neurological disorder.
- Its etiology is often presumed to be vascular.
Observation:
- A patient presented with a single episode consistent with TGA.
- Following this episode, the patient developed a progressive dominant hemispheric syndrome.
Findings:
- Neuroradiologic imaging and post-mortem examination indicated a left temporal-parietal mass lesion.
- This lesion was determined to be the cause of the patient's neurological decline.
Implications:
- While TGA is usually benign, this case underscores the necessity of ruling out structural brain lesions.
- Thorough investigation for mass lesions is crucial in patients presenting with TGA, even if symptoms appear transient.
