Spectrum of Imaging Findings at Chest Radiography, US, CT, and MRI in Multisystem Inflammatory Syndrome in Children...

Area of Science:

• Pediatric radiology
• Infectious disease imaging
• Inflammatory conditions

Background:

• Multisystem inflammatory syndrome in children (MIS-C) is a rare but serious condition following COVID-19.
• Early recognition and diagnosis are crucial for effective management.
• Imaging plays a vital role in identifying the multi-organ involvement characteristic of MIS-C.

Purpose of the Study:

• To describe the spectrum of imaging findings in children with MIS-C.
• To correlate imaging findings with clinical presentation.
• To enhance radiologists' awareness of MIS-C imaging features.

Main Methods:

• Retrospective case series of 35 children diagnosed with MIS-C.
• Review of chest radiography, ultrasound (US), CT, and MRI findings.
• Analysis of thoracic and abdominal imaging features.

Main Results:

• Common thoracic findings included airway inflammation and pulmonary edema.
• Abdominal imaging revealed extensive right iliac fossa inflammatory changes.
• Coronary artery aneurysms were noted in affected children.
• The study identified a constellation of multi-organ imaging abnormalities.

Conclusions:

• MIS-C presents with a distinct pattern of imaging findings across multiple organ systems.
• Radiologists must be aware of these emerging findings for timely diagnosis.
• Comprehensive imaging assessment aids in managing this complex pediatric inflammatory condition.
