Summary
A rare persistent primitive olfactory artery (PPOA) was incidentally found in a patient with vertigo. Computed tomography angiography is valuable for detecting this rare anterior cerebral artery anomaly.
Area of Science:
- Neuroscience
- Vascular Anatomy
- Radiology
Background:
- Persistent primitive olfactory artery (PPOA) is a rare anatomical variation of the anterior cerebral artery.
- Vascular anomalies can present with diverse neurological symptoms or be incidentally discovered.
- Accurate identification of PPOA is crucial for understanding potential associated pathologies.
Observation:
- A 24-year-old woman presented with sudden onset vertigo.
- Computed tomography (CT) angiography revealed a PPOA originating from the terminal right internal carotid artery.
Findings:
- The anomalous artery exhibited a characteristic hairpin turn.
- CT angiography proved effective in identifying this rare PPOA.
Implications:
- PPOA can be easily overlooked due to its rarity.
- CT angiography is a valuable tool for diagnosing PPOA.
- Further monitoring is recommended to assess for potential aneurysm formation.

01:10The Arch of Aorta
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

01:13Radiological Investigation III: Pulmonary Angiogram and PET Scan
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
