case_images: However, plain X-ray imaging (Figure 1) and computed tomography (CT) did not show any fractures, dislocation, or epiphyseal injury.
case_images: Short-TI inversion recovery magnetic resonance imaging. Brachialis muscle was ruptured completely.

case_images: Hence, as we then suspected a soft tissue injury, we performed magnetic resonance imaging (MRI) (Figures 2 and 3) to check for a muscle rupture or an epiphyseal injury.
case_images: T2 magnetic resonance imaging.

case_images: Hence, as we then suspected a soft tissue injury, we performed magnetic resonance imaging (MRI) (Figures 2 and 3) to check for a muscle rupture or an epiphyseal injury.
case_images: Ultrasound examinations (left: one week after the injury; right: two weeks after the injury).

case_images: One week after the injury, ultrasound (US) examinations with broadband (frequency band: 5-17 MHz and 7-12 MHz) small parts of linear array transducers (Figure 4, left) showed scar-like tissues in the area of the brachialis muscle rupture, which were considered as the signs of tissue repair. Subsequent ultrasound examinations were performed over time, and maintenance of continuity was confirmed (Figure 4, right).
