Osteomyelitis Os pubis

Imaging for

acute pelvic pain in pregnancy. A 35-year-old woman presents with pubic pain, fever and elevated inflammatory markers. Coronal T2–weighted HASTE image (a) and T2–weighted STIR image (b) show fluid collection (arrow) at the level of the symphisis pubic bone with hyperintensity of the pubic bone (short arrow). Contrast T1-weighted image shows the presence of a thick vascularised wall indicative of an abscess with a small abscess at the level of left pubic bone (short arrow). These findings are in agreement with osteomyelitis

A novel

observation of pubic osteomyelitis due to Streptococcus viridans after dental extraction: a case report. Magnetic resonance imaging scan of the pelvis showing extensive marrow oedema of the left pubic ramus.

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. 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).
