Calf pain while running. Patient heard "pop" Very minimal questionable soft tissue edema in the subcutaneous fat, please correlate with physical exam. No underlying acute or subacute osseous abnormality, however mild cortical thickening along the anterior aspects is likely related to patient's history and running. If there is concern for possible stress fractures, consider follow-up dedicated imaging such as bone scan or MRI, to increase sensitivity.Soft tissues are grossly and additionally intact, other than the distal Achilles, again consider dedicated imaging if there is a concern this distally.
No acute abnormality, see comments above
