(A, B) Pelvic/hip MRI demonstrating slightly increased signal in the left pubis, adjacent to the pubic symphysis, suggesting ostietis pubis or osteomyelitis. Increased signal reveals mainly to the proximal segment of the obturator internus muscle and hereupon to the obturator externus muscle with little fluid collection, and slight edema of the soft tissue, but with no abscess cavities.
