Ultrasound done. US 8/26- Right anterior thigh superficial subcutaneous soft tissues in the region of interest there is a 1.9x1.2 cm heterogenous, finding without visualized internal color doppler flow, this may be related to injection related changes/injection granuloma or a hematoma. Clinical imaging and f/u to complete resolution are recommended to help excluse other etiologies such as pathological lymph node, an infectious/inflammatory process, or an indeterminate small neoplasm. If there is clinical concern and/or this fails to improve a pediatric surgery consultation is recommended. The left anterior thigh superficial subcutaneous soft tissues in the region of interest there is a 1.3 x0.4 cm mostly anechoic finding suspicious for small seroma, liquefied hematoma, and/or injection related changes, clinical follow-up to complete resolution is recommended to help exclude much less likely etiologies.
