USG

Post-injection Gluteal Hematoma (Intramuscular)

CASE–1

Clinical History

Patient presents with painful swelling in the gluteal region following recent intramuscular injection.

Ultrasound Findings

Ultrasound examination of the gluteal region demonstrates a heterogeneous intramuscular collection within the gluteal musculature at the injection site. Internal echogenic clot/debris is seen. No significant internal vascularity is demonstrated on color Doppler imaging. Mild surrounding soft tissue edema may be present. No definite abscess formation is identified.

Report Line

A well-defined heterogeneous intramuscular collection is seen within the gluteal musculature at the site of recent intramuscular injection, measuring approximately ____ × ____ × ____ mm. Internal echogenic debris/clot is present without significant internal vascularity on color Doppler imaging. Mild surrounding soft tissue edema may be noted. The ultrasound features are consistent with a post-injection intramuscular gluteal hematoma. No sonographic evidence of abscess formation is identified.

Impression

Ultrasound features are suggestive of post-injection intramuscular gluteal hematoma.

Key Learning Points

• Recent intramuscular injection history is an important clue.
• Hematoma appears as a heterogeneous intramuscular collection.
• Internal echoes/debris may represent clot material.
• Color Doppler usually shows no internal vascularity.
• Peripheral hyperemia may suggest inflammation or secondary infection.
• Abscess, injection granuloma, seroma, and soft tissue tumor are important differentials.

Recommendation

Clinical correlation is advised. Follow-up ultrasound may be considered if swelling increases, pain persists, fever develops, or secondary infection is suspected.
