Apply ice It seems like a chronic encapsulated hematoma Get a pediatric surgeon’s opinion Should do a routine CBC and coagulation profile

Ultrasound Report Interpretation Thick-walled: Suggests a chronic process (e.g., organized hematoma, chronic abscess, granuloma). Heteroechoic collection: Means the content of the collection has mixed echogenicity (likely old blood, debris, or fibrous tissue), not just clear fluid. Subcutaneous plane: The collection is superficial, under the skin, and not involving deeper muscles or bones. What This Suggests Given the history of an injection 6 months ago, this is likely a chronic organized hematoma or a post-injection granuloma. If the child has no redness, fever, or tenderness, it might just need monitoring. If the child has redness, warmth, or pain, or if the collection is enlarging, it may need aspiration or surgical drainage. Next Steps Clinical Check: Is the area red, warm, or painful? Is the child walking/crawling normally? Any systemic symptoms (fever, weight loss)? Consider an FNAC or aspiration: If there is doubt, a needle aspiration can confirm the nature of the collection (blood, pus, granuloma). Treatment Decision: If asymptomatic, watchful waiting may be enough. If infected or symptomatic, surgical drainage or antibiotics may be needed.

This needs investigation. Bleeding/ coagulation profile and then decide further course of action

Get CBC, CRP,ESR done

Give vit k
