Symphysitis pubica

Osteomyelitis

pubis with bilateral muscle abscesses. Widening of the symphysis. Intra-articular collection extending anteriorly into the soft tissues, with subtle enhancement at the margins of the collection (orange arrow).

Osteomyelitis

pubis with bilateral muscle abscesses. Bilateral collections along the adductor muscles with butterfly morphology and subtle rim enhancement (orange arrows).

Osteomyelitis

pubis with bilateral muscle abscesses. T1. Widening of the symphysis. Low T1 signal intensity in the pubic rami (red arrows) representing bone marrow oedema surrounding the erosions. Soft tissue extension along the adductor muscles (purple arrows).

Osteomyelitis

pubis with bilateral muscle abscesses. T2 PD, TSE, fs. Widening of the symphysis. Bone marrow oedema in the pubic rami (red arrows). Pus in the symphysis pubis, extending along the adductor muscles (purple arrows).

Osteomyelitis

pubis with bilateral muscle abscesses. T1, fs, Gd. Contrast enhancement of the articular surface (blue arrow), both pubic rami (green arrows) and the soft tissues (yellow arrow). Lymph nodes (small white arrows).

Osteomyelitis

pubis with bilateral muscle abscesses. T1, fs, Gd. Bilateral adductor muscle abscesses (black arrows) with rim enhancement (orange arrows). Enhancement of the adjacent muscle tissue (yellow arrows). Enlarged inguinal lymph nodes (small white arrows).
