Osteitis pubis
From Radipedia
Non-infectious inflammation of the pubis symphasis which can cause abdominal pain.
Imaging shows sclerosis, cystic changes, or rarefaction of the medial portions of the pubic rami (ie, marginal irregularity).
Widening of the cleft usually is measured to greater than 10 mm.
The sacroiliac joints also should be evaluated since laxity of one or both may contribute to pubis symphysis instability.
Positive findings usually are not apparent until 4 weeks after the onset of symptoms.
