A 22 year old college student a cycling enthusiast presented with pain and a nodular stony hard firm swelling in the middle of the anterior third of the right thigh since two months.
The pain started two months back after a period of excessive cycling during a cycling race event; this was followed by a slow growing lesion in the thigh which over a period of two months had become stony hard. Repeated radiographs were normal. Fat planes were maintained. No calcification was noted within the region. An ultrasound examination was done with a 3.5 MHz convex probe.
Rectus femoris compression type intrasubstance tear with chronic hematoma of the muscle belly.
The ultrasound examination reveals a well defined heterogeneous predominantly hypoechoic lesion within the substance of the right rectus femoris muscle. Few hyper echoic strands were noted within it which suggests a fibrous scar. The cystic spaces signify the presence of a seroma.
Tears are most commonly seen in the rectus femoris . It is frequently torn in sports related activities. Tear are of two types:
Distraction tears result when a muscle is abruptly stretched to or above its maximum length.
Compression tears result when a great force is applied to a muscle externally, a crushing injury can occur, called compression tear. Signs of complete rupture are discontinuity of the tendon or muscle.
The quadriceps commonly ruptures transversely at its insertion on the patella.
Healing of partial or complete tears may be seen in various stages.
Immediately after the tear the hematoma is hyper echoic.
Within 12 to 24 hours it starts organizing. In a few weeks it will organize with a seroma in the defect. Ultimate healing is with a fibrous scar which looks hyper echoic.
Surgically unrepaired hematomas develop ossifications seen as hyper reflective regions with posterior acoustic shadowing.
Ultrasound in conjunction with the history and clinical examination can prove to be a simple, non invasive, cost effective, real time, dynamic and effective modality to assess muscle trauma and its various stages of healing.
