Computed tomography and ultrasonography in splenic infarction

Area of Science:

• Radiology
• Medical Imaging

Background:

• Splenic infarction diagnosis can be challenging.
• Imaging modalities like CT and US are crucial for evaluation.

Observation:

• CT findings of splenic infarction include diffuse or focal low-density areas.
• Ultrasound typically shows hypoechoic or anechoic splenic regions.
• Artery embolization was the cause in four of the eight patients studied.

Findings:

• CT features can mimic trauma, inflammation, or tumors.
• Classical wedge-shaped defects may be present peripherally.
• Ultrasound-guided biopsy was needed in one case to rule out abscess.

Implications:

• Accurate CT and US interpretation is vital for diagnosing splenic infarction.
• Understanding imaging characteristics aids in differentiating infarction from other splenic pathologies.
• Further research may refine imaging protocols for splenic conditions.
