Please explain in layman s terms ultrasound of left popliteal fossa & posterior calf?Theres a 4.6x2.3x3.8 cm complex hypoechoic area associated with the distal hamstring, along with the midline posteriorly. The area appears multi-loculated and may represent a hematoma from a hamstring injury. The appearance is not typical of a Barker cyst, due to the position.In addition. at the musculotendinous junction of the distal medial gastrocnemius muscle, there are smaller, hypoechoic area, measuring 8x43x5mm. The appearances are suggestive of a small intramuscular tear, with associated haematoma. The Achilles tendon has heterogeneous hypoechoic areas, with the loss of the normal fibrillary architecture, suggestive of tendinopathic changes of the Achilles.
