Iliopsoas bursitis: The role of diagnostic imaging in detection, differential diagnosis and treatment

Iliopsoas bursitis is characterized by distension of the iliopsoas muscle bursa due to synovial fluid and/or hypertrophic synovium. Hip disease is usually associated with it, however, isolated bursitis is also present. Clinically Diagnosing iliopsoas bursitis can be difficult, and imaging is usually required to differentiate iliopsoas bursitis from other inguinal masses such as lymphadenopathy, hernias, and tumors. We present the case of a 45-year-old athletic patient who underwent diagnostic examination for recurrent right hip pain and a recent development (last 3 months) of a bulky right inguinal mass.

A practical guide for planning pelvic bone percutaneous interventions (biopsy, tumour ablation and cementoplasty)

Percutaneous approaches for pelvic bone procedures (bone biopsies, tumour ablation and cementoplasty) are multiple and less well systematised than for the spine or extremities. Among the different imaging techniques that can be used for guidance, computed tomography (CT) scan is the modality of choice because of the complex pelvic anatomy. In specific cases, such as cementoplasty where real-time evaluation is a determinant, a combination of CT and fluoroscopy is highly recommended. The objective of this article is to propose a systematic approach for image-guided pelvic bone procedures, as well as to provide some technical tips. We illustrate the article with multiple examples, and diagrams of the approaches and important structures to avoid to perform these procedures safely.

TEACHING POINTS

• Pelvic bone procedures are safe to perform if anatomical landmarks are recognised. • The safest approach varies depending on the pelvic level. • CT is the modality of choice for guiding pelvic percutaneous procedures. • Fluoroscopy is recommended when real-time monitoring is mandatory. • MRI can also be used for guiding pelvic percutaneous procedures.
