Summary
A rare case of bilateral pericallosal artery ectasia with stenosis, a condition causing abnormal widening and narrowing of brain arteries, was diagnosed. Definitive diagnosis required conventional cerebral angiography after initial CT and MR imaging.
Area of Science:
- Neuroimaging
- Vascular Neurology
- Radiology
Background:
- Bilateral pericallosal artery ectasia and stenosis is a rare cerebrovascular condition.
- Frontal headache can be a symptom of various intracranial pathologies.
Observation:
- A 49-year-old man presented with frontal headache.
- CT revealed a serpiginous, calcified, contrast-enhancing lesion in the interhemispheric fissure.
Findings:
- Further imaging with MRI and MR angiography was performed.
- Conventional cerebral angiography was ultimately necessary for a definitive diagnosis of bilateral pericallosal artery ectasia with stenosis.
Implications:
- Highlights the importance of conventional angiography in diagnosing complex cerebrovascular abnormalities.
- Contributes to understanding the imaging characteristics of rare arterial conditions affecting the brain.
- Emphasizes the diagnostic challenges in identifying pericallosal artery pathologies.
