Candida Parapsilosis associated rice bodies in the extensor compartment of the wrist--an emerging finding.

Candida parapsilosis has been considered an emerging pathogen with increasing incidence reported in the literature. As a normal commensal of human skin, it is likely that Candida species could gain access to soft tissues of the hand and wrist by direct inoculation, resulting in an infectious tenosynovitis. With the increased prevalence of intravenous drug use (IVDU), users are at increasing risk for musculoskeletal infections including soft tissue abscesses, cellulitis, tenosynovitis, and septic arthritis. Chronic tenosynovitis, with rice body formation in particular, is a comparatively rare musculoskeletal infection. Knowledge of this entity, the related pathogens, imaging findings, and the treatment plan is important not only to the treating clinician, but also to radiologists as the physiological and anatomic consequences can be detrimental to patient recovery.

Intramuscular hemorrhage and fluid extravasation into the anterior compartment secondary to intraosseous resuscitation, the "Nicked-Cortex" sign.

Intraosseous needle access is a reliable method of vascular access used for rapid fluid resuscitation and delivery of medications in certain emergent settings. Fluid extravasation is a possible complication of intraosseous needle access that can lead to compartment syndrome. To our knowledge, imaging findings resulting from this complication have not been described. In this case report, we demonstrate conventional radiograph, computed tomography, and magnetic resonance image findings due to extravasation of resuscitation fluids following the aberrant insertion of an intraosseous needle in an unstable adult trauma patient. We also describe a new radiographic sign associated with this iatrogenic complication, the "Nicked-Cortex" sign.
